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. The PuriSorb series of chloride guard catalysts are used in typical application of chloride (HCl) and Halogenate removal from feedstock in Refinery and Petrochemical applications.
Chempack provide specialty promoted alumina chloride guard adsorbents with excellent performance in overcoming green oil formation, corrosion and fouling problems, the serial chloride guard adsorbents has very high chloride pick-up upto 25% wt/wt, which is typically used in chloride removal in Catalytic Reforming / CCR units, reforming unit of H2 plant, upstream of ZnO Sulfur Removal Bed and other high chloride content streams in refinery to avoid corrosion/fouling of downstream equipments/ vessels.
