Essential for industrial hydrogenation - hydrogen compressor


In recent years, due to the rapid development of petrochemical industry, advanced new hydrogenation process is widely used in petroleum refining industry, which requires the machinery industry to provide complete sets of hydrogenation equipment, and hydrogen compressor is one of them.


Oil Free Hydrogen Compressor

1、 Hydrogen compressor classification


According to the working principle and internal structure, the compressor can be divided into mechanical compressor and non mechanical compressor. Mechanical compressors are divided into liquid driven compressors, diaphragm compressors, linear compressors and ionic liquid compressors; Non mechanical compressors are divided into four categories: cryogenic liquid pump, metal hydride compressor, electrochemical hydrogen compressor and adsorption compressor.


Because hydrogen has the characteristics of low density and small volume energy density, the hydrogen compressor must have the characteristics of large pressure bearing, large flow, safety and good sealing. While preventing hydrogen embrittlement, it should pursue less energy loss as much as possible. At present, liquid driven compressor and diaphragm compressor are widely used in domestic hydrogenation stations.


2、 Working principle of hydrogen compressor


The structure of hydrogen compressor is complex. The more important components include cast iron cylinder, cast iron cylinder liner, cast iron cylinder head, cast iron crankshaft, connecting rod, crosshead (including crosshead slide), packing, piston (including piston ring), oil scraper ring, stainless steel piston connecting rod, stainless steel air valve, etc. in addition, there are some auxiliary equipment, such as gas filter, buffer, lubricating oil pipeline, etc. Like other reciprocating compressors, hydrogen compressors include three processes: suction, compression and exhaust. Driven by the motor, the crankshaft drives the crosshead, piston connecting rod and piston to move back and forth in the cylinder. The gas is compressed by the piston and finally discharged through the air valve.


3、 Application of hydrogen compressor


1. In the chlor alkali industry, the main function of hydrogen compressor is to cool and purify the high-temperature wet hydrogen from the electrolysis process, pressurize the transmission, maintain the stable pressure of the hydrogen system, and ensure the safe and stable operation of the electrolytic cell.


2. At present, the huge environmental pressure and the gradual depletion of fossil fuels and traditional energy make countries all over the world actively seek new clean energy. Hydrogen energy and hydrogen fuel cell have attracted more and more attention all over the world because of their good environmental protection performance, high energy conversion efficiency and certain economy. In order to promote the development of hydrogen energy, the improvement of hydrogen energy infrastructure is essential. Hydrogen compressor is one of the three core and key monomer equipment required for the construction of hydrogenation station.
