METHOD FOR COMPRESSING MIXED GAS CONSISTING OF COMBUSTIBLE GAS AND AIR

摘要

A novel method for compressing mixed gas consisting of combustible gas and air without risk of explosion of the mixed gas is described herein. In the novel method, the mixed gas is compressed under coexistence of non-combustible liquid such as water. In one preferred embodiment, a water-sealed compressor as represented by a Nash pump is used for compressing the mixed gas, and water contained in the compressed mixed gas is separated and fed back to the water-sealed compressor to assure existence of sealing water in the compressor.
