Lower costs for converting alkylation units from hydrofluoric to sulfuric acid

For petroleum refineries, the cost of converting hydrofluoric-acid-based alkylation units to the relatively safer sulfuric-acid-based alkylation process (diagram) has been cost-prohibitive and has lacked specific economic benefits. Now, DuPont (Wilmington, Del.; www.dupont.com) has developed a low-cost approach to converting existing…
