Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, including the dangers related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on site and the wider setting should leaks occur.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important safety element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ laws has increased the demand for alkylate, which can additionally be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation course of poses a selection of critical environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. เกจวัดco2 by its nature seeks out and attacks imperfections in solid metallic parts that can finally cut back the life of pumps, valves and other gear and worse still, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the selection of fabric of solid parts, particularly in phrases of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed to be used in hydrofluoric acid alkylation items and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation expertise 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 methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent era pumps are features which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 supplies, which has been confirmed to supply the required 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 potential for leakage into the surroundings, and lowering operational dangers and the related prices to fulfill stringent environmental and well being and security goals. Finally, there is continuous monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting techniques, the latest magnetic drive sealless pump expertise presents significant safety, value and operational advantages. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
