Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to process operators, including the risks related to the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the wider surroundings ought to leaks occur.
The course of
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 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 unpolluted fuels’ legislation has elevated the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential dangers
The HF alkylation process poses a quantity of severe environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in forged steel parts that may in the end reduce the life of pumps, valves and other gear and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of fabric of solid elements, significantly in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply 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 shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive development process, the HMD Kontro HF pump includes a high 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 options
Built into the design of these subsequent technology pumps are options which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been confirmed to offer the mandatory 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 possibility of leakage into the surroundings, and decreasing operational risks and the related prices to fulfill stringent environmental and health and safety targets. Finally, there’ เกจวัดแก๊สlpg monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and protection towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting methods, the latest 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 comparison with conventional mechanically sealed pumps.
