Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, including the risks related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant tools, the people who work on web site and the broader 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 supply alkylate. A high-octane additive, alkylate is a important security part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ laws has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
เกจวัดแรงดัน poses numerous severe environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in forged steel components that may ultimately scale back the life 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 importance on the choice of material of cast components, significantly in terms of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids such as HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation units and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an innovative growth course of, the HMD Kontro HF pump includes a excessive 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 features
Built into the design of those next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been confirmed to offer the required resistance to corrosion and also meets NDE necessities 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 environment, and decreasing operational risks and the related prices to meet stringent environmental and well being and security objectives. Finally, there’s continuous monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump operating (power control monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the most recent magnetic drive sealless pump expertise presents important security, value and operational advantages. Lower end-user installation costs and simplified upkeep necessities, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
