Question: What is the sulfur separation process for sulfur production? Answer: In the sulfur production method using sulfur separation, two-thirds of the acidic gases are introduced into the combustion furnace, with the amount of air supplied being sufficient for the complete combustion of H2S and hydrocarbons. This stream is then mixed with two-thirds of the acidic gas in front of the primary converter, where, under the action of a catalyst, H2S and SO2 react to form S.
The sulfur production method using sulfur separation involves introducing one-third of the acidic gas into the combustion furnace, with the amount of air supplied being sufficient for the complete combustion of H2S and hydrocarbons. This gas is then mixed with two-thirds of the remaining acidic gas before the primary converter; under the action of a catalyst, H2S reacts with SO2 to produce S.
The partial combustion method for sulfur production involves burning all of the acidic gases

The reaction in the combustion furnace of the fractional sulfur production process occurs on a 100% stoichiometric basis; that is, all of the hydrogen sulfide in the acidic gas is burned to form sulfur dioxide, with no sulfur being produced

One-third of the acidic gas is fed into the combustion furnace, where air is added to cause it to burn and produce sulfur dioxide; the remaining two-thirds of the acidic gas takes a bypass route, passing around the combustion chamber, and then merges with the gases produced after combustion to enter the catalytic bed for reaction. This system can handle acidic gas containing approximately 35% hydrogen sulfide, and it employs a three-stage conversion and three-stage condensation process flow.

This system can handle acidic gas containing approximately 35% hydrogen sulfide, and it employs a three-stage conversion and three-stage condensation process flow.
This process can be used when the concentration of acidic gas H2S is below 50% but above 15%. (1) The typical split-flow process is as follows: 1/3 of the acid gas volume, along with the measured amount of air, enters the combustion furnace where H2S is completely converted into SO2. This gas stream then passes through a waste heat boiler and mixes with the remaining 2/3 of the acid gas before entering the catalytic conversion reactor. In this process, sulfur is entirely generated within the catalytic section. (2) Unconventional diversion process: When the amount of acid gas entering the combustion furnace is more than 1/3, some sulfur is generated within the combustion furnace.
