Optimization of the sulfur recovery process can be achieved by creating a flexible group in the ROP that limits total elemental sulfur production in the two SRUs to 390 LTPD on a 12-month rolling time period, which is equivalent to the combined total of the current ROP-allowable 12-month rolling time period limits for the two SRUs.

The sulfur recovery from low-concentration nitrogen-diluting SO 2 flue gas is destined to be energy intensive and accompanied by massive CO 2 emissions. In the current context of "carbon neutrality", there appears an urgent need to find new sulfur sources and reduce energy consumption and carbon emissions during the production process.

In general, gas processing plants and oil refineries are required to recover between 95 and 99.99 percent of the total sulfur introduced to the SRU. A conventional 2-stage SRU, …
