API RP 751 - Safe Operation of Hydrofluoric Acid Alkylation Units

Explore this topic

API RP 751, Safe Operation of Hydrofluoric Acid Alkylation Units, is a recommended practice developed and published by the American Petroleum Institute (API) that provides guidance to refinery operators on the safe operation of hydrofluoric acid (HF) alkylation units, which are key refinery assets used in the production of cleaner transportation fuels required to meet today’s more stringent environmental standards. This RP was originally published in 1992, and the most recent 5th Edition was released in August of 2021.  

API RP 751 includes recommendations (“should”) and certain requirements (“shall”) on hazards management, operating procedures, worker procedures, material inspection and maintenance, transportation and inventory control, relief and utility systems, and risk mitigation. Moreover, the document provides additional information on the elements of a comprehensive HF audit, HF exposure limits, and corrosion & materials considerations specific to HF alkylation units.
