520 _aTranscripción del resumen presentado por el autor, en inglés: Environmental regulations controlling the amount of H2S emissions require the Aquila Navasota Gas Plant to treat the acid gas from the main amine-treating unit to meet standard specifications. Originally, a batch process was installed to remove a portion of the H2S, bypassing the remaining gas, to meet the specifications. Operating cost of this batch process increased as the H2S content increased and became excessive. This required Aquila to investigate alternative processes. Process evaluations were requested from several sources and a large variance in unit designs was found. Due to the unique nature of the feed gas, 96+% CO2 and < 1000 ppm H2S at 10 psig, conventional design technology for amines required a higher circulation rate and excessive CO2 absorption. Since the recovered H2S would be sent to a flare, fuel consumption would be higher with the excess CO2. One design, provided by Huntsman Corporation, was found to offer the lowest capital investment along with lower operating cost. This design utilized specific design parameters in the absorber that allowed the circulation rate to be less than one-third of the other designs. Unit operating parameters will be reviewed and have been within original estimates. Design also allows for a wide range of operating conditions without much change in treated specifications. Design and operating characteristics will be reviewed.
