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.

1, gas welding of purple copper plate: welding purple copper plate is most commonly used for butt joints, lap joints and ding joints are used as little as possible. Gas welding can be used in two kinds of welding wire, one containing deoxidizing elements, such as wire 201, 202; the other is the general purple copper wire and the cutting strip of the parent material, using gas 301 as flux. Gas welding purple copper should be used when the neutral flame. 2, manual arc welding of purple copper: in...
