There are two main types of cleaning methods for reactors: mechanical cleaning and chemical cleaning. Mechanical cleaning: A high-pressure cleaning device is used to clean the reactor wall and the surface of the stirrer with a high-pressure water stream through the nozzle. Chemical cleaning: The first step is to know the composition of the scale sample in the reactor equipment, preferably by taking a sample and analysing it. After determining the composition of the dirt, do a test and choose a cleaning agent that will not cause corrosion to the equipment metal. Then set up a temporary circulating device on site to circulate the cleaning solution in the equipment to wash away the dirt. (1) First rinse the stirring paddle and kettle walls with an appropriate amount of water and drain. (2) Flush the reactor with solvent through the pressurised device stream. (3) If the cleaning effect is not achieved, add an appropriate amount of solvent to the reactor to warm up and stir the reflux until the cleaning requirement is achieved.Then the solvent is released. (4) Finally, rinse the inner wall of the reactor with a certain amount of solvent and release. The two methods have their advantages and disadvantages, chemical cleaning with less labour, short cleaning time, cleaning thoroughly, but may cause the equipment is corroded; mechanical cleaning will not produce corrosion of equipment, the hard scale can be effectively cleaned, but long, labour-intensive. Therefore, chemical cleaning is used in the softer, thinner dirt, mechanical cleaning is used in the hard, thick dirt conditions. #Pressure Vessels#Storage Tanks http://www.wxnqpv.com

Pressure Vessels Fractionation and Distillation of Petroleum Oil is not only an important source of energy, but also an important raw material for chemical products (such as plastics). Scientists say that there is only a limited amount of oil on the planet and predict that by the end of the 21st century, the planet's oil resources may be exhausted. The search for new sources of energy has therefore become a major trend, including research into 'synthetic oil' or 'synthetic fuel oil' to replace virgin oil. We are all familiar with this part of the story, but there are a number of curious questions that we would like to clarify. 1. Is it true that oil will be depleted in the near future? 2. How is oil produced? 3. petrol is derived from oil, what would cars and planes do without it, and is there a way to make petrol? Oil fractionation The composition of oil is roughly classified as: oily (this is its main part), gum (a viscous semi-solid substance), asphaltene (a dark brown or black brittle solid substance), and carbon (an inorganic carbonaceous substance). Oil contains more than 300 types of hydrocarbons, some with short molecular chains and low boiling points, and some with long molecular chains and high boiling points; therefore, industry uses this difference in boiling points to fractionate oil. In industry, the oil is first heated to between 400°C and 500°C, where it is turned into vapour and then fed into a fractionating tower. The oil vapour rises in the fractionation tower, the higher the position, the lower the temperature, and hydrocarbon gases with different boiling points condense into liquid fractions at different heights. Gaseous fractions with short molecular chains and low boiling points will condense at the upper levels of the fractionation tower, for example Fuel gas and liquefied petroleum gas (mainly propane and butane, which can be used as fuel or as other chemical feedstock). Gasoline (mainly used as fuel for aircraft and vehicles). Light oil (also known as naphtha, it is a mixture of various hydrocarbons (hydrocarbons) and is used to make alkene chemicals such as ethylene and propylene, and benzene chemicals such as toluene and xylene). Paraffin (mainly used for aircraft and household fuel). Gaseous fractions with long molecular chains and high boiling points which condense in the lower part of the fractionation column, e.g. Diesel fuel (mainly used as fuel for buses, heavy vehicles and factories). Fuel oil (mainly used as fuel for ships, factories, power plants). Lubricating oils, wax oils, etc. At the bottom of the fractionator, the viscous residue left behind is heavy oil (in which viscous, high molecular weight hydrocarbons are the main component, also containing gums, asphaltenes and some inorganic substances, the heavy oil can be cracked to produce some oils of small molecular weight, and the final residue is bitumen). The different fractions are collected in the various layers, exported through conduits and separated out of the fractionation column. These fractionation products are all petrochemical raw materials from which many chemical products can be made again. Distillation tower is a tower-type gas-liquid contact device for distillation, using the mixture of components with different volatility, that is, at the same temperature of the components of the different vapour pressure of this nature, so that the liquid phase of the light components (low boiling material) transferred to the gas phase, and the gas phase of the recombination (high boiling material) transferred to the liquid phase, so as to achieve the purpose of separation. The distillation column is also an extremely widely used heat transfer device in petrochemical production. #Pressure Vessels#Distillation Column http://www.wxnqpv.com/

As the continuous high temperature increases the threat to the safe storage of hazardous chemicals, Wuxi Nanquan Pressure Vessel Co., Ltd. strengthens safety protection and does a good job in preventing heat and cooling to prevent fire and explosion accidents! Why is the risk high in high temperature? 1. The temperature rises to increase the volume pressure of hazardous chemicals Thermal expansion and contraction is a general physical phenomenon of objects. If the pressure inside a container increases beyond the limit that the container can withstand, it will cause the container to fail or even blow up. If the container is open, the liquid expansion beyond its capacity will spill over and run, bubble, drip, leak. To prevent this from happening, in addition to taking measures to prevent heat and cool down, the filling coefficients should also be filled according to the regulations. In the case of gases, the coefficient of expansion is greater and the gases are generally filled in cylinders, which are at risk of explosion as the temperature rises and the pressure becomes too high. 2. Increased temperature accelerates oxidative decomposition and spontaneous combustion Influenced by environmental factors such as temperature and humidity, many hazardous chemicals are prone to decomposition when heated, releasing oxygen and even oxygen atoms, which oxidise other substances and give off a lot of heat at the same time. If ventilation is poor, the heat will accumulate and not dissipate, resulting in a rise in temperature, which in turn will accelerate the rate of oxidation and generate more heat, prompting the temperature to continue to rise. Wuxi Nanquan Pressure Vessel Co., Ltd. has done the following measures 1. Strictly control the temperature Set up a water storage roof for the warehouse or set up cooling water pipes on the roof of the warehouse to cool the warehouse when the temperature is above 30 degrees Celsius, so that the temperature in the warehouse is kept below 28 degrees Celsius. In the warehouse roof laying gravel sacks, can enhance the heat insulation performance of the roof, but also the warehouse roof, external walls and window glass painted white, the use of white on the reflection of sunlight, reduce the absorption of radiation heat, to achieve the role of cooling. According to the nature of the goods and packaging, you can pour well water, put ice on the ground in the warehouse, and install air conditioning to cool down the temperature if possible. Some warehouses can open windows in the morning and evening and at night to ventilate and let in cold air, and close doors and windows at noon to prevent hot air from entering. 2. Storage tanks to be cooled The top of the storage tank should be set up with a cooling device, and when the temperature reaches above 30 degrees Celsius, turn on the cooling water pump for spraying and cooling. The storage tank should not be filled too full, the tank is generally only 90% to 95% of the volume, leaving 5% to 10% of the volume space, which can prevent the hazardous chemicals in the tank from burning or exploding due to heat expansion. 3. Strengthen personnel management Personnel managing dangerous chemical warehouses must be trained in safety and qualified by examination, and be licensed to work. The warehouse management personnel should regularly inspect the warehouse and solve problems in time to ensure safety. #Pressure Vessels#Storage Tanks http://www.wxnqpv.com

How to choose the most suitable pressure vessel gas storage tank? The main role of air storage tanks in air compression systems is to ensure a stable air supply. Compressed air in the tank to precipitate water, adjust the pneumatic equipment due to unbalanced air volume and air pressure fluctuations, increase the pressure stability of air equipment, or reserve part of the compressed air, in the event of a compressor failure, so that the user with this part of the compressed air for pneumatic equipment or pneumatic control system for emergency purposes, therefore, the selection of a suitable pressure vessel storage tank, is to protect the entire air system The key link. How to choose the most suitable pressure vessel storage tank? We offer some guidance from 3 aspects: pressure, volume and material. Pressure selection Depending on the pressure of the tank, it can be divided into high pressure tanks, low pressure tanks and atmospheric tanks. Selection of gas storage tank pressure as long as it is greater than or equal to the exhaust pressure of the air compressor, that is, the pressure is 8 kg, the choice of gas storage tank pressure is not less than 8 kg. Volume selection The volume size of the optional storage tank is approximately in the range of 0.3-0.5 of the exhaust volume of the air compressor; if the environmental conditions allow, you can choose a large volume storage tank, which helps to store more compressed air and better pre-distribution of water. Example: If the air compressor exhaust volume is 1 cubic metre per minute and the pressure is 8 kg. According to the formula for selecting a storage tank, the volume of the tank = the exhaust volume of the compressor * 0.3 or the exhaust volume of the compressor * 0.5 range, (not less than one-third or one-fifth of the exhaust volume), the recommended volume of 0.3 cubic meters or 0.2 cubic meters of storage tank; if the subsequent still need to increase the amount of air, the volume of the tank can also be appropriate to enlarge the space, such as the choice of 0.5 cubic meters, or 0.6 cubic metres, or 1 cubic metre, etc. Material selection Depending on the material chosen, gas storage tanks can be divided into carbon steel tanks, low-alloy steel tanks and stainless steel tanks, which are used in conjunction with air compressors, cold dryers, filters and other equipment to form compressed air stations as a power source for industrial production. Most industries choose carbon steel tanks and low-alloy steel tanks (low-alloy steel tanks have higher yield strength and toughness than carbon steel tanks and are relatively more expensive); stainless steel tanks are mainly used in the food industry, medical and pharmaceutical, chemical industry, microelectronics and other equipment and machine industries that require high overall performance (corrosion resistance and formability). Users can choose according to the actual situation.

Pressure vessels are enclosed equipment loaded with liquids and gases and subject to high pressures, or with fluids inside that can form pressures, as well as equipment subject to external pressure, etc. Corrosion, cracking, breakage, erosion and physical damage are the most obvious forms of failure of pressure vessels. Pressure vessels and accessories are often subject to major catastrophic accidents due to corrosion, deterioration, alteration and cracking of materials, most of which are caused by corrosion. A complete structure of the pressure vessel, often due to the use of the process of neglecting the corrosion problem and caused by the application period decline or damage failure, causing safety accidents, in the specific operation must be profoundly aware of the use of scientific strategies to prevent. The main influencing factors of corrosion in pressure vessels 1. External environmental reasons The internal and external environment of the pressure vessel will directly affect its anti-corrosion performance. Pressure vessels carry more types of reagents, containing many material costs, will inevitably be mixed with a small amount of corrosive materials, such as acidic materials, alkaline materials, etc., these components are very likely to lead to pressure vessels corrosion phenomenon. External environmental causes of corrosion on the pressure vessel is a variety of forms of impact, one, the pressure vessel in the application of corrosion, the rise in internal pressure will play an obvious catalytic effect, accelerate the corrosion reaction, and then worsen the corrosion problem. Second, the temperature in the pressure vessel will accelerate the reaction rate, the temperature rises, ion flow rapidly, the internal temperature rises every 10 ℃, the chemical reaction rate will accelerate 2 times to 3 times. Third, the internal acid and alkali environment will catalyse the rate of corrosion reaction, acid and alkali environment is not the same, the internal ion content will be different. 2. Material characteristics factors Pressure vessel material characteristics greatly affect and determine the level of corrosion resistance of the pressure vessel. First, the corrosion rate will be subject to surface metal substance crystal structure density and oxidation interference, the greater the crystal structure density, the rougher the surface, the greater the crystal pore slit, the service material is more likely to deep, the more likely to appear corrosion reaction. Second, in the use of pressure vessels, if the content added to the pressure is too large and internal calcination and other phenomena, when the internal pressure is very strong, are likely to lead to changes in the pressure vessel, and then cause corrosion reactions, if the internal H2S at this time, the container is very likely to corrosive damage. Thirdly, if the pressure vessel material composition, will accelerate the electrochemical corrosion reaction rate. In the composition of the mixed pressure vessel, very easy to meet the original battery reaction to read, if the internal appearance of inert materials, then it will accelerate the rate of metal corrosion.

packed tower tower type selection of general principles. Tower packing is the core component of the packed tower, which provides an effective phase interface for heat and mass transfer between the two phases of gas and liquid, only the excellent performance of the tower packing and then supplemented by the ideal tower parts, is expected to constitute a technically advanced packed tower. The following situations are given priority to packed towers. In the case of a high degree of separation requirements, because some new fillers have high mass transfer efficiency, so new fillers can be used to reduce the height of the tower. For the distillation and separation of heat-sensitive materials, as the new filler holds less liquid, the pressure drop is small, so the packed tower under vacuum operation can be preferred. With corrosive materials, packed towers can be used. Because the packed tower can be used non-metallic materials, such as ceramics, plastics, etc.. Easy to foam materials, it is appropriate to use packed tower. 2, packed tower filler selection. Geometric characteristics of the filler data mainly include specific surface area, void ratio, packing factor, etc., is to evaluate the performance of the basic parameters of the filler. ① surface area The packing surface area per unit volume of packing is called the specific surface area, expressed in a, its unit is m2/m3. the larger the specific surface area of the packing, the greater the gas-liquid transfer area provided. Therefore, the specific surface area is an important indicator to evaluate the performance of the filler. ②Vacancy rate The volume of voids in the unit volume of filler is called the void ratio, expressed as ε, and its unit is m3/m3, or expressed as %. The larger the void ratio of the filler, the greater the ability of the gas to pass and the lower the pressure. Therefore, the void ratio is another important indicator to evaluate the performance of the filler. ③Filler factor The specific surface area of the filler and the cubic ratio of the void rate, that is, a ∕ ε3, known as the packing factor, to Ф, its unit is 1/m. It indicates the fluid mechanical properties of the filler, Ф value is smaller, indicating that the smaller the resistance to flow. 3, the filler performance is usually based on efficiency, flux and pressure drop three elements to measure. Under the same operating conditions, the larger the specific surface area of the filler, the more uniform distribution of gas and liquid, the better the wetting performance of the surface, the higher the mass transfer efficiency. The larger the void ratio of the packing, the more open the structure, the higher the flux and the lower the pressure drop.

Many customers confuse reaction kettles with stirred tanks, but in fact there is no clear demarcation point between these two types of equipment, as reaction kettles can also be called stirred tanks, and some stirred tanks can also be called reaction kettles. Both reaction kettles and stirred tanks are containers used for stirring and mixing. The structure of reaction kettles is designed to be closed, while stirred tanks can be designed as open lid tanks or as closed form tanks. Difference between stirred tank and reactor. 1 Structure: The upper cover of a reactor is either a head structure or a conical structure; the upper cover of a stirred tank can be a flat cover structure or a head structure. 2 Sealing: The seal of the reactor is high and mechanical seal is required; the seal of the mixing tank is made into mechanical seal or packing seal according to the requirements. 3 Cost: The structure of the reactor is more complex and the cost is higher; the structure of the stirred tank is simpler and the cost is relatively low. 4 Operation observation: The reactor needs the assistance of accessories such as sight glass, pressure gauge and liquid level meter to observe the material inside the tank; the open cover type stirred tank can observe the material inside the tank by opening the cover or the population. Reaction kettles and mixing tanks are similar in shape and structure, both can heat, stir and keep warm the material, and are installed in the same way, both can be used in the production line for mixing of liquid and liquid-solid. There are more types of stainless steel mixing tanks, including single-layer mixing tanks, double-layer mixing tanks, thermal insulation mixing tanks, vacuum-type mixing tanks, pressure-type mixing tanks, most of the reaction kettles refer to tanks that need to be vacuumed or work under a certain pressure, so the reaction kettle can be a type of mixing tank.

Detailed classification of pressure vessels according to their use Pressure vessels are sealed vessels that are subjected to gas or liquid pressure internally or externally and have high requirements for safety. Pressure vessels are mainly cylindrical, a few are spherical or other shapes. Cylindrical pressure vessels are usually composed of cylinder, head, receiver, flange and other parts and components, the higher the working pressure of the pressure vessel, the thicker the wall of the cylinder should be. According to the role of the process can be subdivided into four main categories. 1, storage pressure vessels (C, of which the spherical tank for B): mainly for storage, holding gas, liquid, liquefied gas and other media pressure vessels, such as various types of storage tanks. 2, reaction pressure vessel (R): mainly used to complete the physical and chemical reaction of the medium pressure vessel. Such as reactor, reactor kettle, decomposition pot, vulcanization tank, decomposition tower, polymerization tower, autoclave, ultra-high pressure kettle, synthesis tower, transformation furnace, cooking pot, steam ball, autoclave, gas generator, etc. 3, heat exchange pressure vessel (E): mainly for the completion of the medium of heat exchange pressure vessel. Such as shell and tube waste heat boiler, heat exchanger, cooler, condenser, evaporator, heater, disinfection pot, dyer, drying cylinder, steam frying pan, preheating pot, solvent preheater, steam pot, steam off machine, electric steam generator, gas generator water jacket, etc. 4, separation pressure vessel (S): mainly used to complete the medium of fluid pressure balance buffer and gas purification and separation of pressure vessels. Such as separator, filter, oil collector, buffer, scrubber, absorption tower, copper washing tower, drying tower, steam tower, sub-vapor cylinder, deaerator, etc. #Pressure Vessels#Distillation Column http://www.wxnqpv.com/
