Abstract

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.

CNG acid gas removal process. Final technical report

Technical Report Auyang, L; Liu, Y

Work under Contract DE-AC21-80MC14399 comprised four tasks designed to advance development of the CNG acid gas removal process: Task 1 - development of a modified carbon dioxide triple-point crystallizer, Task 2 - acquisition of basic process data, Task 3 - extension of the process to low carbon dioxide content crude gases, and Task 4 - fate of trace contaminants in the CNG process. Task 2 covered crystallizer operation and data acquisition, other process data acquisition unrelated to the crystallizer, and process design studies. Task 2 is comprised of five subtasks.

Two tasks were active during the ninth quarter of the CNG acid gas removal project: Subtask 1.4, calibration of instruments and elimination of equipment difficulties for the process development-scale triple-point crystallizer; and Subtask 2.1, acquisition of crystallizer rate and mechanical slurry handling data. Within Subtask 1.4, slurry pumping difficulties were resolved by extending the flash zone (longer flash vessel), and by placing a coarse filter over the slurry outlet port to exclude large particles from the slurry pump suction line. The slurry pump is a 0.5-inch ECO gear pump. Successful slurry pumping permitted a solid bed several feet tall tomore »« less

Four tasks were active: design and construction of a bench-scale triple-point crystallizer; equilibrium data acquisition, crystallizer separation factors for several sulfur-containing molecules and trace contaminants, and slurry pumping. A new design for the CNG crystallizer has been completed. A control scheme was devised for the new design. Equipment sizing, selection, and procurement is in progress. Equilibrium data acquisition has been completed. Five component vapor-liquid equilibrium data for gas mixtures representative of BCR Bi-Gas and Exxon catalytic gasifier crude gases were measured. The experimental data agree very well with the equilibrium data estimated by computer calculations. Separation factors were determined formore »« less

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 formationmore »« less

During the second quarter of the CNG Acid Gas Removal Project, 4 subtasks were active. Within Subtask 1.1, melter design studies were performed to identify methods of improving melting rates in the CNG crystallizer. Greatly enhanced melting rates are thought possible with a melter configuration that excludes liquid carbon dioxide from the melting region and allows more intimate contact of the vapor and solid carbon dioxide. Also within Subtask 1.1, a review of triple-point desalination process literature was completed. Within Subtask 2.2, reconstruction and testing of the vapor-liquid solid equilibrium apparatus is nearly complete. Test operation with the carbon dioxidemore »« less
