Chloride & Halogen Removal
The presence of chloride in refinery streams typically comes from the crude oil and the catalytic reforming unit. In common, the form is inorginic chloride but sometimes certain crude oil do contain species of organic chlorides can not be removed in the desalter easily. The most common source of chloride comes from the catalytic reforming unit which is injected with cloride on to the catalyst for optimal conversion and selectivity.The effects of chloride in downstream operations can cause corrosion of the steel equipments like pipes and prossure drop problems.
Chloride adsorbent are widely used in oil refinery, petrochemical, ammonia, natural gas, coal chemical plants to protect the downstream catalyst, pipe and equipment.
