Describe

Plant capacity: 1000~3×10⁴Nm³/h（LNG）

Technical characteristics:

Using one segment isothermal bed of methanation technology, the entire process is very short, process gas goes through the reactor at one time and no circulating gas or recycle compressor, the plant achieve minimization of investment and maximization of profit, and have low cost and save energy. The investment of methanation section is reduced 30% compared with the foreign technology.

Application scope:

Coke oven gas、coal gasification gas and synthesis gas including CO,CO₂ and H₂
