Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, including the risks associated with the dealing with of a deadly, highly corrosive fluid which poses a possible hazard to plant equipment, the people who work on web site and the wider environment ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important security component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ laws has elevated the demand for alkylate, which can additionally be responsible for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential dangers
The HF alkylation process poses numerous severe environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in solid metal parts that will finally reduce the lifetime of pumps, valves and different tools and worse still, end in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations great significance on the choice of fabric of forged parts, particularly in phrases of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed for use 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 shut collaboration between UOP Honeywell, the leading licensor of HF alkylation technology and HMD Kontro, and using an revolutionary development process, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using เครื่องมือที่ใช้วัดความดันคือ of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these next generation pumps are features which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to supply the required resistance to corrosion and in addition meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the risk of leakage into the surroundings, and lowering operational risks and the related costs to meet stringent environmental and health and safety targets. Finally, there’s continuous monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and safety against dry pump running (power management monitor).
With no seals to leak, no seal buffer systems to help and keep and no supporting techniques, the latest magnetic drive sealless pump technology provides important security, value and operational benefits. Lower end-user set up prices and simplified upkeep requirements, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
