Comparison of process options for sulfur recovery.
Thread Content
Please share your opinions on which sulfur recovery process is the best choice to use in conjunction with space furnaces, low-temperature methanol washing, and liquid nitrogen washing processes As well as their respective advantages and disadvantages, thank you. Urgent need!

Reply 1# guowei00007: The conditions specified by the original poster are too limited to allow for the recommendation of a suitable process solution. The H2S content in the acidic gas, along with the sulfur production volume, should be presented together to facilitate the selection of process options. If the sulfur production is low (generally, less than 20 tons per day), LO-CAT can be chosen; this process operates at normal temperature and pressure, with the H2S content in the exhaust gases typically being less than 4 PPm, which meets all regulatory requirements. However, the catalysts used are entirely imported, which increases the operating costs and makes the option uneconomical when sulfur production is high. If the H2S content in the acidic gas is high and sulfur production is significant, processes such as Super Claus or SCOT can be chosen; in China, the SSR sulfur recovery process is also a suitable option. Therefore, please provide more details on the acidic gas conditions; otherwise, it will be impossible for everyone to choose a suitable process scheme. ,
