Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses particular challenges to process operators, including the risks related to the handling of a deadly, highly corrosive fluid which poses a possible hazard to plant tools, the people who work on site and the wider surroundings ought to leaks happen.
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important security component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
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 related HF launch. HF acid by its nature seeks out and assaults imperfections in solid metallic parts that may finally cut back the life of pumps, valves and other tools 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 importance on the choice of fabric of forged components, notably in phrases of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids corresponding to 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 for use in hydrofluoric acid alkylation units and were 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 expertise and HMD Kontro, and utilizing an revolutionary development course of, the HMD Kontro HF pump includes a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 supplies, which has been proven to offer the mandatory resistance to corrosion and in addition 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 decreasing operational risks and the associated costs to meet stringent environmental and health and safety targets. Finally, there is xp2i monitoring to ensure a reliable sealless pump performance which incorporates leak detection instrumentation and protection towards dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to assist and preserve and no supporting systems, the newest magnetic drive sealless pump technology provides important safety, cost and operational advantages. Lower end-user installation costs and simplified maintenance necessities, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
