CNG acid gas removal process. Technical progress report No. 7, 1 May-31 July 1982
Two tasks were active during the seventh quarter of the CNG Acid Gas Removal project: Subtask 1.3 - design and construction of a bench-scale triple-point crystallizer; and Subtask 2.5 - water removal. Subtask 1.3 was completed; crystallizer design and construction is summarized. Within Subtask 2.5, water removal, the likelihood of hydrate formation in the CNG acid gas removal process has been examined. Calculation of hydrate formation conditions for a five component, water saturated, crude coal gasifier gas at 1156 psia indicate hydrate formation is possible at about 9 to 10/sup 0/C. The influence of various trace contaminants on hydrate formation is difficult to predict; most likely, the hydrate formation temperature is lowered by the presence of water soluble contaminaants such as ammonia. 13 references, 10 figures, 9 tables.
