Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to process operators, including the risks related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, 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 produce alkylate. A high-octane additive, alkylate is a crucial security component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. 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 modern automobiles.
Potential dangers
The HF alkylation process poses a number of severe environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in forged metallic parts that can in the end reduce the lifetime of pumps, valves and different gear and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the selection of fabric of solid parts, particularly by means of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids similar to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed for use in hydrofluoric acid alkylation models and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and utilizing an revolutionary improvement course of, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing เกจ์วัดความดัน of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these next generation pumps are options which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the necessary resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the setting, and lowering operational dangers and the related costs to satisfy stringent environmental and health and safety targets. Finally, there’s steady monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection towards dry pump operating (power management monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting systems, the most recent magnetic drive sealless pump expertise provides vital safety, value and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition in comparison with conventional mechanically sealed pumps.
