Abstract: The problems in Chlorsorb chlorine adsorption process in a continuous catalytic reforming unit in a refinery were analyzed, where the reforming catalyst surface area declines accelerately, discharge gas cooler outlet corrosion and discharge emission beyond standards occurs. Two kinds of solid dechlorination schemes are discussed, which use the antichlor GL-1 developed by SINOPEC Research Institute of Petroleum Processing for dechlorination of regenerated flue gas. In order to remove the HCl in the discharge gas to eliminate the influence of HCl on corrosion of the unit and avoid the catalyst from contacting with regenerated flue gas with high water content and make the discharge gas in compliant with the new regulations for HCl and non methane hydrocarbons, a solid dechlorination technology instead of Chlorsorb dechlorination process is suggested.
