The HF alkylation process is an important part of modern refinery gasoline production. This program, “HF Alkylation Process Technology,” has been developed by Refining Process Services to provide an in-depth yet practical review of HF Alkylation Unit Operation. The speakers will cover topics ranging from the basic process principles through items of current interest such as operations troubleshooting and methods of HF detection and leak mitigation. Key process variables such as feedstock quality, reaction conditions, and catalyst composition will be discussed. Various unit configurations by both UOP and Phillips Petroleum licensors will be reviewed and control of the unit to meet product specifications will be taught. A thorough understanding of these principles is required for safe and reliable operation of the HF alkylation unit.

Program participants will have the opportunity to obtain a broad working knowledge of the HF alkylation process including some history of the process and important metallurgy and corrosion aspects. Participants will be invited to submit questions for discussion during the program.
