Advantages of the nitrogen cycle process of liquid air separation plant

Generally, the main reason for the vibration of piston type oxygen compressor is the action of alternating load. There are two kinds of alternating loads: one is the unbalanced inertia force, the other is the interference force caused by the strong gas pressure pulse in the gas pipeline caused by the discontinuous gas supply of the compressor. The vibration caused by unbalanced inertia force can be eliminated and reduced from the structure of the machine itself. The specific methods are as follows: reasonably arrange the crank stagger angle; properly select the mass configuration of reciprocating parts. In addition, the basic design and manufacturing process of the compressor should also strictly comply with the technical specifications. For the vibration caused by air flow pressure pulse, a buffer can be installed near the cylinder exhaust pipe nozzle; the appropriate installation position of orifice plate should be selected on the gas flow channel; the shock absorber should be

Biogas purification is the removal of impurity components from biogas to make high quality CH4 with high methane content, calorific value and impurity gas components that meet the requirements of natural gas standards. The biogas produced by the anaerobic fermentation process contains approximately 55% CH4 and 45% CO2, as well as small amounts of H2S, H2O and other gaseous components, which can be increased to over 95% by separation and purificat...
