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.
Application
ACR-1 is an outstanding Ca/Zn adsorbent most commonly used in adsorbing hydrogen chloride from reformer hydrogen off-gases, natural gas, naphtha, and light liquid hydrocarbons in low-temperature range applications. It can provide more than 15% chloride pick-up capacity at 30℃, and its chloride pick-up capacity rises with operating temperature in the range of -5℃ to 200℃.
ACR-2 is an alkali metal chloride adsorbent most commonly used in adsorbing hydrogen chloride from reformer hydrogen off-gases, synthesis-gas,natural gas, naphtha and light liquid hydrocarbons in wide temperature range applications(ambient up to 400℃), the chloride pick-up capacity increased while operating temperature changes, the lab scale pilot test show the capacity is up to 50%.
This product utilities activated alumina as carrier with varying levels of Na2O promoter impregnation. The product’s primary method of removal is both chemisorption and absorption. It utilises the high service area of the alumina to absorb the HCl compound, but it also utilises promotion to react with the HCl.
