Control the air volume entering the sulfur production combustion furnace so that the H2S/SO2 ratio in the process gas at the outlet of the three-stage condenser is 2/1.
How is the sulfur recovery ratio control system adjusted? Air-to-fuel ratio control target: Control the air volume entering the sulfur production combustion chamber so that the H2S/SO2 ratio in the process gas at the outlet of the three-stage condenser is 2/1.
I really don’t know about this; please provide some information
Through automatic control of the air-to-gas ratio, the stability of the H2S/SO2 ratio is significantly improved, providing optimal reaction conditions for sulfur production burners and reaction converters. This enhances the conversion rate, reduces the sulfur content in the exhaust gases, lessens the load on the hydrogenation unit in the exhaust gas treatment process, and lowers the sulfur content in the purified exhaust gas at the outlet of the absorption tower. As a result, the total amount of sulfur emitted into the atmosphere by the facility is reduced.
Convert as much of the sulfur in acidic gases as possible into sulfur, and minimize the amount of sulfur released into the atmosphere
How is the sulfur recovery ratio control system adjusted? Answer: By utilizing the HCHACS control software platform and the proprietary technology for controlling the H2S/SO2 ratio, algorithms are provided from the perspectives of process analysis and system identification. Advanced control strategies are employed to design primary/secondary air distribution controllers, which work in conjunction with the DCS to regulate the air distribution volume. This approach helps to eliminate the effects of factors such as non-linearity, large time lags, and variations in the amount of acidic gases on the H2S/SO2 ratio, thereby improving the stability of this ratio and bringing it as close as possible to 2:1.

Generally, the air supply is adjusted according to the amount of acidic gas. When the furnace tip temperature is low and the value read by the ratio analyzer is small, it is possible to increase the air supply to the middle section； When the burner temperature is high and the ratio is large, the air supply to the middle section can be reduced.
A control system that achieves a certain proportional relationship between two or more parameters is called a ratio control system. A system that typically maintains a certain proportional relationship between the flow rates of two or more materials is called a flow ratio control system. Ratio control systems can be classified into: open-loop ratio control systems, single closed-loop ratio control systems, double closed-loop ratio control systems, variable ratio control systems, and systems that combine cascade control with ratio control.
