Contents Notes
The report gives results of an examination of various methods of solvent regeneration in an acid gas removal system (AGRS) coupled to a fluidized-bed coal gasifier. (Earlier research on acid gas removal using refrigerated methanol had shown that, when a high purity gas is desired as a product gas, the most critical step i the process is solvent regeneration.) The composition of the absorber exit gas stream (the sweet gas) obtained from each system configuration studied was used as a basis for comparing the various schemes. For the systems studied, the ability of the acid gas removal system to produce a conditioned gas with low levels of Hb2sS and COb2s was found to be governed primarily by the purity of the solvent entering the absorber, and thus by regeneration conditions. These results are believed to be general for refrigerated methanol systems and, together with mathematical models developed as a part of the project, can provide a basis for selecting an optimum configuration for an acid gas removal system. The fate of the various trace compounds produced in the gasifier was determined, and a design method for predicting the exit stream in which these compounds leave the AGRS was proposed.
