1. Remove chlorine from the reformed hydrogen； 2. Prevent chlorine from corroding subsequent equipment, which could lead to accidents such as the formation of ammonium chloride that blocks pipes.
On the one hand, to prevent rate corrosion during the lifting process； On the other hand, it improved the purity of reduced hydrogen.
Remove chlorine from hydrogen to prevent corrosion of pipelines in downstream equipment. The format for the weekly question can follow that of other sections in the Petrochemical Region; the main activities in the region are listed below.
Remove chlorine from hydrogen to improve purity
Remove chlorine to reduce chlorine-induced corrosion and ammonium salt clogging in subsequent hydrogenation units
The destination of the reformed hydrogen is generally the users (such as regeneration and boosting units, pretreatment units, isomerization units, etc.), with the main destination still being hydrogen purification units. Therefore, I believe that the dechlorination of reformed hydrogen is not aimed at purification, but rather at reducing corrosion in downstream pipelines and equipment. It is also related to the requirements placed on the chlorine content in the feedstock by the catalysts used in hydrogen purification units, that is, to protect the PSA catalysts
Removes hydrogen chloride, protects subsequent heat exchangers and other equipment, and reduces chlorine corrosion and ammonium salt clogging in the subsequent hydrogenation units
