Two tasks were active during the eight quarter of the CNG Acid Gas Removal Process Project. Subtask 1.4.: testing and calibration of the process demonstration-scale triple-point crystallizer equipment and instrumentation; and Subtask 2.5 water removal. Subtask 1.4 was completed. Startup procedure is discussed. Procedures for testing and calibrating the crystallizer components and the integrated system are explained and test results are presented. Problems detected during the tests were corrected. Results of initial test runs are discussed. Subtask 2.5 was completed. Three alternative water removal schemes were examined: (1) conventional absorption/regeneration using dimethyl formamide (DMF) or methyl isobutyl ketone (MIBK), (2) absorption using methanol with subsequent condensation of methanol, and (3) adsorption using molecular sieves. The fate in the CNG Process of remaining trace water was examined. The sparse solubility of water in liquid carbon dioxide is sufficient to cause essentially complete absorption of water by liquid carbon dioxide in the hydrogen sulfide absorber. Water is rejected with the acid gases by crystallization. 19 references, 11 figures, 7 tables.
