How to calculate SO2 in coke oven flue gas

Based on the determination of hydrogen sulfide content in gas

It mainly involves calculating the amount of hydrogen sulfide converted to sulfur dioxide

I’ll try to answer: generally, hydrogen sulfide in gas is easy to measure, while organic sulfur is difficult to determine due to the variety of organic sulfur compounds. Since we have a methanol production process using coke oven gas, one of the steps in dry desulfurization is the hydrogenation of organic sulfur. By measuring the hydrogen sulfide content in the gas after hydrogenation of iron and molybdenum, it is possible to determine how much sulfur dioxide can be generated when the organic sulfur in the gas is burned back in the furnace. Additionally, the volume of coke oven gas increases by 6-7 times after combustion, and the sulfur dioxide content in the flue gases can be calculated using the molecular weights of hydrogen sulfide and sulfur dioxide. Just my opinion. As an additional note, if there is a leak in the coke oven, the sulfur content in the flue gas will be much higher.
