Air compressor in the chemical plant core role analysis
as a key equipment in chemical production, air compressor provides stable air source and pressure support through compressed air, and plays an irreplaceable role in process flow, equipment drive, gas treatment and safety guarantee. Its core functions can be summarized as follows:
1. Process Core Power Source
Chemical reaction pressurization
In the production of synthetic ammonia, methanol and polyethylene, the air compressor provides a high-pressure environment for the reactor. For example, ammonia synthesis needs to pressurize nitrogen and hydrogen to 15-30MPa, and the compressor ensures that the gas reaches the reaction threshold through multi-stage compression, which significantly improves the reaction rate and product yield.
Gas separation and purification
In the air separation device, the compressor compresses the air and cools it, and uses molecular sieve adsorption technology to separate oxygen, nitrogen and other components. In the field of natural gas processing, the compressor realizes carbon dioxide removal and methane purification through pressurization to meet the purity requirements of industrial grade gas.
the refrigeration system drives
the storage of chemical raw materials, and the compressor drives the refrigerant cycle to maintain the low temperature environment of the warehouse. For example, ethylene storage requires a low temperature below -100 ℃, and the compressor realizes the refrigerant phase change through the compression-expansion cycle to ensure the stability of the raw material.
2. Equipment Operation Foundation Support
the pneumatic control system
provides power for pneumatic valves, regulating valves and actuators to achieve precise control of process parameters. In the continuous production device, the compressor guarantees the stable gas supply of 0.4-0.7MPa for the pneumatic instrument and ensures the real-time adjustment of temperature, pressure and other parameters.
Pneumatic tools drive
pneumatic drills, spray guns and wrenches and other equipment to improve maintenance and production efficiency. Compared with electric tools, pneumatic equipment has the advantages of explosion-proof and lightweight, and is suitable for flammable and explosive chemical environment.
3. gas treatment and recycling
Remote gas transportation
In the long-distance natural gas pipeline, compressor stations are arranged at intervals, and the multi-stage pressurization overcomes the pipeline resistance to ensure that the gas is transported to the user end thousands of kilometers away.
Exhaust gas recovery booster
compresses the catalytic cracking tail gas and other exhaust gas back to the reaction system to recover high-value components such as ethylene and propylene, so as to realize resource recycling and reduce emissions.
4. safety and environmental protection key guarantee
Unit start-stop safety control
During the start-up phase, the compressor delivers nitrogen for pipeline replacement to eliminate air and other impurities to avoid explosion risk; during shutdown, the system pressure is safely released to prevent equipment overpressure damage.
High-risk environment ventilation guarantee
In flammable and explosive workshops, compressors drive axial fans to maintain air circulation, control the concentration of combustible gases, and reduce the risk of explosion.
Conclusion
By providing stable air source and pressure control, the air compressor becomes the "dynamic thread" of the production system of the chemical plant ". Its role runs through the whole process from raw material processing to product storage, which not only ensures the efficient operation of the process, but also ensures production safety and environmental compliance. With the development of technology, innovative applications such as frequency conversion energy saving and heat recovery are further enhancing the comprehensive value of air compressors in the chemical industry.
Granklin 37kw air compressor equipment parameters? 37kw air compressor is a very popular machine sold by Granklin Group, which is 37kW in line with the scenes used by most small and medium-sized enterprises. It is enough to purchase 2 37kW water-lubricated air compressors, one for each and two sets of water-lubricated air compressors.
View detailsThe oil content standard of screw air compressor is usually stipulated by relevant international, national or industry standards. Generally speaking, for oil-injected screw air compressors, the oil content of compressed air is not more than 3ppm (I .e. the oil content per cubic meter of compressed air is not more than 3 mg)
There are some significant differences in the design and operation of oil-injected and oil-free compressors, which are mainly reflected in the lubrication method, the use effect and the applicable environment.
For the question of whether the 2 cubic compressed air storage tank needs to be reported, the answer depends on the design pressure of the storage tank and other relevant factors. If the design pressure of the gas storage tank is greater than 1kg (or 0.1 MPa), it needs to be reported according to relevant regulations.
The air compressor outlet pressure setting range usually varies according to the use scenario and demand. The following are some common air compressor outlet pressure setting range and professional terms explanation: general industrial use: outlet pressure setting range is usually 6 ~ 8b
The maintenance cycle of the screw air compressor usually depends on the use of the equipment and the manufacturer's recommendations. Generally speaking, the maintenance cycle of the screw air compressor can consider the following aspects: Operating hours: Many manufacturers recommend running the equipment for a certain number of hours
As an important industrial equipment, air compressor has a wide range of application scenarios. The following is a description of the use scenario of the air compressor, which is classified and summarized according to different industries and applications: 1. Industrial manufacturing Pneumatic tool Power source: In industrial manufacturing
Oil-free compressed air refers to compressed air that does not add any oil lubrication during the compression process using an air compressor. According to ISO8573 standards, oil-free compressed air must meet certain requirements, that is, the oil content must be less than 0.01 mg/m & sup3;, up
A large amount of compressed air is required in the semiconductor manufacturing process, which is mainly due to the necessity of compressed air in many key process steps. The following is a detailed analysis of the reasons: 1. process control semiconductor production involves many sophisticated process steps, such as lithography, engraving.
In industrial production, compressed air is an important power source, and its pressure stability is directly related to production efficiency and equipment safety. So, how much of the compressed air pressure in the factory is normal? It actually depends on the specific application scenarios and equipment requirements. generally come
