| Abstract: | Considerable attention has been devoted to a higher rate of the sulfur recovery rate and less emission of SO2 in the field of sulfur recovery and tail gas treatment. Using specially developed hydrogenation catalyst, the newly developed low temperature SCOT technology with optimization design on the units has improved operational stability and flexibility so as to save much capital cost and energy and reduce consumption. Compared to traditional processes, this SCOT technology has a far more promising prospect of development in tail gas approach. |
