Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to process operators, including the dangers associated with the dealing with of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the wider environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within 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 stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of clean fuels’ legislation has increased the demand for alkylate, which can also be liable 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 well being 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 attacks imperfections in forged metal components that may finally reduce the life of pumps, valves and other equipment and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice significance on the selection of fabric of forged components, significantly in terms of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply whole 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 dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an innovative improvement process, the HMD Kontro HF pump includes a high 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 options
Built into the design of those next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been proven 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 for leakage into the surroundings, and reducing operational risks and the related prices to meet stringent environmental and well being and security targets. Finally, there could be เกจอาร์กอน monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and protection in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer techniques to support and preserve and no supporting methods, the most recent magnetic drive sealless pump technology presents vital safety, cost and operational benefits. Lower end-user installation prices and simplified upkeep requirements, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
