Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, together with the risks related to the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on site and the wider surroundings ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important safety element that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which can also be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential dangers
The HF alkylation process poses a number of critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in solid metal components that may finally reduce the life of pumps, valves and other gear and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great significance on the selection of fabric of solid elements, significantly in phrases of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation items and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an revolutionary development process, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent era pumps are features which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply the required resistance to corrosion and likewise 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 surroundings, and lowering operational dangers and the associated costs to meet stringent environmental and well being and security goals. Finally, there is steady monitoring to ensure a reliable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to support and maintain and no supporting methods, the latest magnetic drive sealless pump know-how presents significant safety, price and operational benefits. Lower end-user set up prices and simplified upkeep necessities, make it an efficient whole-life proposition compared to conventional mechanically sealed pumps.
