The report gives results of an evaluation of two mobile pilot-plant scrubbers (one alkaline, the other Stretford) for removing reduced sulfur compounds from the offgas of an in-situ retort at Geokinetics. The alkaline scrubber had a tray tower and a venturi contactor used alternately with NaOH, KOH, and NH4OH to investigate the effects of scrubbing chemical, chemical concentration, and residence time on removal efficiency and H2S selectivity. The Stretford plant employed a venturi contactor (near the end of the test, a packed-tower contactor was added downstream of the venturi). A computer model of the alkaline scrubber, based on the penetration theory, was developed and agrees well with the observed performance. Based on this model, it appears possible to design an alkaline scrubber system that can achieve 95% H2S removal at a selectivity of 37.
