Three tasks were active during the fifth quarter of the CNG Acid Gas Removal project: Subtask 1.3 design and construction of a bench-scale triple-point crystallizer; Subtask 2.4 slurry pumping; and Task 4 fate of trace components. Within Subtask 1.3, safety considerations for the present CNG triple-point crystallizer system are summarized. These include: (1) building safety features, (2) crystallizer safety features, and (3) personnel safety features. Within Subtask 2.4, the minimum net positive suction head required for a MicroPump gear pump to successfully pump slurries of solid carbon dioxide in an organic liquid carrier solvent has been determined. Task 4, determination of the fate of trace contaminants in the CNG acid gas removal process, is complete. Trace contaminants anticipated in the crude gas entering acid gas removal are removed to acceptably low levels by the CNG process and rejected with the acid gases. With the possible exception of benzene, no recycle loops or accumulation of contaminants occur in the CNG process. Combinations of feed gas pressure and benzene contamination which may cause deposition of solid benzene are defined. 21 references, 10 figures, 6 tables.
