The presence of chloride in refinery streams typically has two sources: crude oil and the catalytic reforming unit. While less common, certain crude oil assays do contain species of organic chlorides that are not removed in the desalter. The most common source of chloride, however, is the catalytic reforming unit. These units utilize metal and acid functionality, with chloride injected and adsorbed onto the catalyst to provide the acid function necessary for optimal conversion and selectivity.
This chloride is not permanently bound to the support and is therefore sent out with all product streams. Effects of chloride in downstream operations can be:
A fixed bed of PURASPEC chloride absorbent is the best solution for this problem. We offer products for the removal of inorganic and organic chloride; levels which can vary depending on the chloride source among other factors. Johnson Matthey can provide a tailored solution that is specific to the application and offers technology packages beyond just the material where requested.
Performance is key when it comes to chloride guard materials. Poor materials will result in the formation of debilitating factors such as the formation of organic chlorides or green oils. These will result in premature outages of very expensive pieces of equipment and deration of valuable refinery processes. PURASPEC materials have been formulated to provide the best protection against these undesired products, giving the user peace of mind that they are doing the most that they can to maximize profitability and reliability within their plant.
