Hong Kong and Tokyo, Japan – March 20, 2017 – BASF developed a new technology for tail gas treatment and will present it at GASTECH in Japan, for the first time in public. This latest addition to BASF’s gas treatment portfolio, marketed under the brand OASE® yellow T, can boost the performance of the overall sulfur removal unit (SRU) in refineries. OASE yellow T significantly decreases the sulfur emissions from tail gas treatment units and lowers operational expenditure due to the reduced amine circulation rates and reboiler duties. This new technology allows an increase in the overall throughput and, therefore, the capacity of the SRU system in place. OASE yellow T can be implemented into a running tail gas treatment unit, and does not require any change of existing equipment.
The tail gas treatment process converts sulfur dioxide contained in the tail gas from the Claus process into hydrogen sulfide, which will be absorbed by the amine solution, and returns it to the Claus process, thereby achieving a high rate of sulfur recovery.
