Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to course of operators, together with the risks associated with the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the broader setting ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a critical security part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ laws has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential risks
The HF alkylation process poses a variety of critical environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in cast metal elements that will finally reduce the life of pumps, valves and other gear and worse still, end in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of material of solid parts, particularly by method of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation items and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and utilizing an progressive development process, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new methods of Non-Destructive Examination (NDE).

Built into the design of these next technology pumps are options which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential for leakage into the environment, and reducing operational risks and the associated costs to meet stringent environmental and well being and safety targets. Finally, there’s continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer techniques to assist and keep and no supporting techniques, the latest magnetic drive sealless pump know-how offers important safety, price and operational advantages. Lower end-user installation prices and simplified upkeep necessities, make it an effective whole-life proposition in comparison with conventional mechanically sealed pumps.
