Abstract
The paper discusses the use of EPA's mobile wet scrubber on a 200-acfm slipstream of Geokinetics' retort offgas to investigate the H2S removal efficiency and selectivity (percent H2S removal/percent CO2 removal) as a function of liquid/gas contact time, alkaline solution OH(minus) concentration, and the specific scrubbing chemical. A venturi and spray tower were used to produce contact times of about 0.003 and 0.2 second, respectively. Three alkaline solutions (NaOH, KOH, and NH4OH) were employed on each contactor at various concentrations for a total of 22 runs. To analyze these results and provide design criteria for future alkaline scrubbers a sophisticated computer model employing the penetration theory for liquid-phase mass transfer was developed.
