Low Temperature Shift Catalyst

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. 

Is the B217 LTS catalyst self-guarding, or is a Chloride & Sulfur Guard needed?

 Low temperature shift(LTS) catalyst B217 catalyst is used for CO conversion process in the syngas productions of ammonia plant, same as HTS catalyst.  ●Self-guard catalyst: Yes it is. Chloride & Sulfur guard is not needed to load of the top of low temperature shift(LTS) catalyst B217. It can remove trace chloride and sulfur during the running. ●Chloride&sulfur guard: It is guard catalyst(5%-10%) of some brands, to protect the main LTS catalyst for reaction. If customers want to keep the same loading mode of previous brands, we can supply chloride and sulfur guard also.
