Can the process gas air compressor use Granklin water to lubricate the air compressor?

Can the process gas air compressor use the water lubricated air compressor produced by Granklin Group?

The compressed gas used in different petroleum and chemical fields is different. Realistically speaking, not every kind of gas is suitable for the use of water lubricated air compressor, in the oil-free air compressor is currently the best use of water lubricated air compressor, but the different characteristics of the gas determines whether the appropriate use.

In the petroleum and chemical industries, due to the different types of petroleum and chemical production and process reactions, the fluids transported by the compressor are very different. These fluids range from non-corrosive to highly corrosive; from non-toxic to highly toxic; and highly volatile, flammable and explosive gases. Exhaust pressure from low pressure gas. The pressure sound Pd is less than 0.2MPa (gauge pressure), and the exhaust end pressure is above I000MPa MPa (gauge pressure). Therefore, the form of the compressor is also various.

petroleum, chemical industry with air compressor refers to the petroleum, chemical process in the transport of various gases used in the compressor and in the process outside the transport of various gases with the compressor. In the petroleum and chemical process, the compressor for transporting various gases is actually not much different from the compressor for transporting various gases outside the process. The main difference between them lies in the chemical compressor, which is different in materials and design, mainly to prevent corrosion and adapt to the characteristics of the chemical process.

The compressor is very complex in structure, sealing form and material application, and has high requirements and difficulties in operation, maintenance technology, maintenance and management. The normal operation of the compressor is the key to ensure production, if the compressor fails. It will affect normal production, and even cause semi-stop production, full stop production or cause safety and equipment accidents. Therefore, the maintenance and repair of the compressor occupies an extremely important position in the chemical production process.

In recent years, with the development of petroleum and chemical industries, petroleum and chemical compressors are developing in the direction of high speed, high capacity, corrosion resistance, durability and standardization. There is also a need to develop various types of compressors for conveying special gases. Therefore, there are many problems to be discussed in the design of the compressor. Such as in the gas characteristics of the compressor. Special requirements for sealing, materials, structure and manufacturing processing of the same topic, transmission mode. Maintenance and safety aspects, etc.

With the development of high technology and the deepening of energy-saving transformation of old factories, the production process of China's petroleum and chemical industries will develop towards serialization and large-scale. High quality and low consumption of products are the main goals of enterprises, which requires long-term, safe and economic operation of chemical production. Therefore, the applicability and reliability of petroleum and chemical compressors are particularly important.

The special requirements of petroleum and chemical production for compressors are roughly the following.

(1) can adapt to the needs of chemical process

compressor in the chemical production process, in addition to the role of gas transport. It also provides the necessary transport (pumping) of material to the system. If you want the compressor to be stable and balanced in the chemical reaction process. and meet the pressure required for chemical reactions. It is required that the displacement of the compressor is relatively stable. Once the production fluctuation is affected by some factors, the pressure and outlet pressure of the compressor can also change accordingly to meet the requirements of the process.

(2) Corrosion resistance

most of the media transported by petroleum and chemical compressors, including raw materials and intermediate products, are corrosive. If the material of the compressor is improperly selected, the parts will be corroded and failed when the compressor is running, that is, it cannot continue to work.

For some gas media, if there is no suitable corrosion-resistant metal material, non-metallic materials can be used. In the selection of materials, it is necessary to take into account its corrosion resistance, but also its mechanical properties, cutting performance and price.

(3) Reliable operation

the reliable operation of chemical compressors includes two aspects: long-term operation without failure and various parameters in operation are stable and reliable, which are very important to chemical production. If the compressor often fails, it will not only cause frequent shutdown, affect economic benefits, and sometimes cause safety accidents in the chemical system. For example, the delivery of nitrogen as an isolation system suddenly stops during operation, which may cause violent reaction, overheating, high temperature, and even explosion, causing a fire. The fluctuation of the compressor speed will cause the fluctuation of the exhaust volume and the compressor outlet pressure, so that the chemical production can not operate normally, the reaction is affected, and even the quality of the produced products is reduced or scrapped.

(4) Environmental protection, no leakage

most of the gas media transported by compressors for petroleum and chemical industries are flammable, explosive, toxic and harmful. If these gaseous media leak into the atmosphere from the compressor, it may cause fire or environmental pollution and harm the human body. Some gas media are expensive, and leakage will cause great waste. Therefore, the chemical compressor requires no leakage, which requires the compressor sealing, daily maintenance, maintenance quality work. The selection of good sealing material and reasonable sealing structure can make the shaft seal leak-free; in the process of operation, daily maintenance and overhaul, it is also an effective means to prevent leakage according to the management regulations (process operation procedures and maintenance procedures).

It can be seen from the requirements of petroleum and chemical industry in medicine that it is very strict. There are not many series of process gas air compressors that can meet this kind of requirements. Among the series of argon air compressors, oxygen air compressors, nitrogen air compressors, etc., the water-lubricated oil-free air compressors of Shanghai Grankering Group fully meet the usage scenarios of this series.
