Cost of biogas purification

Centrifugal compressor, sometimes suddenly produce strong vibration in the production process, gas medium flow and pressure also appear substantial pulsation, and accompanied by periodic dull "call" sound, as well as airflow fluctuations in the network caused by "huffing" "huffing" strong noise, this phenomenon is known as the centrifugal compressor wheezing conditions in small air separation unit. According to the prod...

The liquid air separation plant includes the lower tower, upper tower, condensing evaporator, argon system, main heat exchanger, subcooler, liquefier and is placed in a separate cold box. After distillation in the lower tower, high purity nitrogen is obtained at the top of the lower tower, which is reheated by the main heat exchanger and then exits the cold box and goes to the nitrogen circulation system to recover the cold from the liquid air separation plant to make liquid nitrogen. The lower ...
