Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of operators, together with the risks associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on site and the broader surroundings ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a important safety element 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’ legislation has increased the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential risks
The HF alkylation process poses a selection of severe environmental and health and security risks 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 solid steel components that will finally reduce the lifetime of pumps, valves and other equipment and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great importance on the choice of material of solid components, particularly in phrases of the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed to be used in hydrofluoric acid alkylation models and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and utilizing an revolutionary improvement 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).
Specialist design features
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been proven to supply the mandatory resistance to corrosion and also 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 setting, and lowering operational risks and the related prices to meet stringent environmental and well being and security goals. Finally, there’s steady monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer systems to support and maintain and no supporting techniques, the latest magnetic drive sealless pump technology provides important safety, value and operational benefits. เกจวัดแรงดันแก๊สอาร์กอน -user set up costs and simplified maintenance necessities, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
