PURPOSE: An apparatus for dehydrating and refining methane gas is provided to recover the concentrated methane gas with high purity by refining and removing condensed water and other impurities included in digestion gas. CONSTITUTION: An apparatus for dehydrating and refining methane gas with an anaerobic digestion mode includes a compressor(100) dehydrating and refining digestion gas, a first and a second condensers(200a,200b), an expansion valve(300), an evaporator(400), and a gas storage tank(500). The refrigerant compacted through the compressor is flowed into the first condenser via a first flow path(1) and a second flow path(2). The refrigerant liquefied is flowed into the second condenser via a fourth flow path(4). The flow paths are connected by 3 way valves(10,20). |
