Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of operators, including the risks associated with the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on web site and the broader surroundings should leaks occur.
The course of
HF Alkylation combines olefins (primarily a combination 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 excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential risks
The HF alkylation process poses a variety of serious environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in cast metal elements that will finally scale back the life of pumps, valves and different gear and worse nonetheless, result in product leakage. เกจวัดแรงดันสูง -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places great significance on the selection of material of cast elements, particularly in terms of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and utilizing an innovative 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 utilizing new methods of Non-Destructive Examination (NDE).

Built into the design of these next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the risk of leakage into the surroundings, and decreasing operational risks and the related costs to fulfill stringent environmental and health and security goals. Finally, there’s continuous monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and safety towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting systems, the newest magnetic drive sealless pump expertise provides vital safety, value and operational advantages. Lower end-user installation prices and simplified maintenance requirements, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
