Conditioning Coal Gas with Refrigerated Methanol in a System of Packed Columns

摘要

The paper discusses potential difficulties in the operation of acid gas removal systems gases produced from coal, based on experience with pilot-scale unit operation. The pilot plant has been used to condition gases produced from subbituminous coal, devolatilized char, peat, and lignite. The solvent used in the acid gas removal system has been refrigerated methyl alcohol. Data from this study document accumulation of hydrocarbons, sulfur and nitrogen compounds, and mercury in the circulating solvent.
