What is the allowable Chloride and Sulfur content in the LTS feed gas?
Both low temperature shift and high temperature shift catalysts are used for CO conversion process, working in series reactors of ammonia plant.
●Chloride content of LTS feed gas: Lower than 0.1 ppm. Normally, the sulfur content at CO conversion stage is quite low.
●Sulfur content of LTS feed gas: Lower than 1 ppm. Normally, the chloride in this stage usually comes from vapor.
