Hydrogen consumption range and adjustment methods for sulfur recovery hydrogenation reaction
Thread Content
I would like to ask if any expert knows what the factors that influence the hydrogen consumption in the hydrogenation reaction of sulfur recovery units are, and what the basis for such adjustments is I would appreciate your advice.

Flow regulation can be combined with the results of analytical tests, or with online analyzers for measuring hydrogen content in exhaust gases. This value is relatively fixed; it is usually adjusted very rarely. The basis for adjustment is ultimately the hydrogen content in the exhaust gases; this is generally determined by analyzing the content at the outlet of the quench tower, with the typical control range being 2–4% (v).
The process gas enters the hydrogenation reactor from the inlet air heat exchanger of the catcher, then goes to the quench tower and subsequently to the absorption tower
