High gravity coal gas lock purification technology
Coal lock gas "refers to the gas containing dust and tar released by the coal lock during the coal pressure gasification process. Under normal pressure, it needs to be pressurized by a compressor before entering subsequent processes. The tar dust content in the gas from the gas cabinet of Xinjiang Guanghui New Energy Co., Ltd. exceeds 1000mg/m ³, causing the compressor to be blocked and unable to operate normally. Coal lock gas can only be used to light sky lanterns, resulting in environmental pollution and resource waste.
The high gravity wet dust removal technology uses gasification circulating water as the purification medium, with a liquid consumption of only 8m ³/h. The tar dust content in coal lock gas is about 500-1000mg/m ³. After being purified by supergravity wet method, the tar dust content in the gas is around 20-80mg/m ³, and the purification rate can reach over 90%. The annual recovery of gas is 230 million m ³. The working cycle of the compressor has been increased from 5 days to over 6 months, and the purification effect is good. Solved the industry problem of environmental pollution and resource waste caused by the combustion emissions of coal lock gas torches.
The promotion and application of this technology in the Xinjiang Xintian Coal Chemical Coal to Natural Gas Project has good prospects for industrial application.
