Abstract： |
Production of methane from land-filled garbage gas and its apparatus are disclosed. It is carried out by pressing the abstracted land-filled garbage gas, freezing drying, multi-stage filtering, pretreatment process of adsorption drying, high-pressure adsorbing, co-current pressure equalizing, constant-pressure recovering, and pressure varied adsorption circulating. The apparatus consists of compressors connected orderly, freezing direr, filter, drying tower and pressure varied adsorption circulating system with 2-6 parallel adsorbing columns. Its advantages include simple apparatus and operation, low cost and good flexibility. |
