How to improve the economic efficiency of oxygen generator operation in air separation equipment

What are the key points for daily maintenance of air compressors in the operation system of air separation equipment?

What factors are related to the cooling capacity of the expander

The raw air is compressed to about 0.52Mpa by the air compressor after filtering out dust and impurities, and then cooled to about 10℃ by the refrigerant glycol aqueous solution or Freon, and then enters the purification system to purify and remove water, carbon dioxide and other impurities in the air. Part of the raw material air enters the lower tower via the second raw material air pipeline, another part is liquefied into liquid air via the liquefier and enters the lower tower via the liquid ...

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...

  It is recommended to degrease aluminium parts (pressure vessels, valves, pipelines) with perchloroethylene or trichloroethylene solvents, and carbon tetrachloride (CC14) solvents are strictly prohibited. The solvent must be oil-free and degreased, and decomposed solutions are not allowed. Organic solutions are not suitable for assemblies with rubber, plastic or organic coatings. Organic solvents are toxic and flammable and should be used with care.   In addition t...
