Non-destructive refined nitrogen purification device (reference case)
Biogas concentration technology
In this technology, methane（CH4）-rich biogas is pressurized by a compressor, and after desulfurization treatment, the impurity gas is removed by pressure swing adsorption technology to obtain concentrated high-purity methane gas.
The process flow is simple and reasonable, and the operation is convenient
Large processing scale, high yield and high product purity
The domestic leading technical level
