Policy support for biogas purification

Untreated biogas has high methane content and low purification cost. This is mainly due to the increase of energy production, and the total cost is related to higher energy level. The cost can be reduced by improving efficiency (reducing energy consumption per unit output) and using raw biogas with high calorific value to reduce actual energy consumption.

The amount of circulating nitrogen required for a liqued air separation plant

The liqued air separation plant cooling capacity is cooled between the air compressor and the nitrogen compressor, resulting in a significant reduction in energy consumption and a 50% saving in energy consumption. At the same time the introduction of liqued air separation plant cold capacity eliminates the chiller, expander, but increases the cold balance of the liquefier, in the heat transfer calculation is more difficult in low temperature conditions, the performance of the fluid changes more ...
