Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to process operators, including the risks related to the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on web site and the broader setting ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a crucial safety element that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of poses a variety of serious environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in cast metal elements that can finally reduce the lifetime of pumps, valves and other gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of fabric of cast components, notably when it comes to the pump casing and impeller.
Designed for resistance against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed to be used in hydrofluoric acid alkylation units and have been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and utilizing an progressive improvement course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent technology pumps are options which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been proven to supply the required resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential for leakage into the environment, and reducing operational dangers and the related prices to satisfy stringent environmental and health and security goals. Finally, there could be continuous monitoring to ensure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer techniques to assist and maintain and no supporting methods, the newest magnetic drive sealless pump expertise presents vital security, value and operational benefits. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
