Excessive hydrogen sulfide levels in the purified dry gas from coking process
Thread Content
Before desulfurization, the dry gas volume was 9,000 standard cubic meters, and the dry gas temperature was 26 degrees. The circulation rate of the lean liquid was 60 tons, with a concentration of 28%. The sulfide content in the lean liquid was 600 ppm, and its temperature was 34 degrees. The pressure in the desulfurization tower was 10 kilograms; the pressures before and after the tower remained stable, as did the liquid level and the concentration of the lean amine solution. I hope an expert can analyze why the hydrogen sulfide level in the dry gas is 30% above the limit. What could be the cause? ? ? Thank you
What is the ratio of liquid volume to dry gas volume for the operator? We also often exceed the limit here, thank you
What is the ratio of the amount of lean liquid to the amount of dry gas?
