Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to process operators, together with the risks associated with the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on website and the wider environment should 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 provide alkylate. A high-octane additive, alkylate is a critical security part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential dangers
The HF alkylation process poses a variety of serious environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in cast metal components that may ultimately reduce the life of pumps, valves and different equipment and worse nonetheless, lead to 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 material of solid elements, significantly in phrases of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation units 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 utilizing an innovative development course of, the HMD Kontro HF pump contains 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 options
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and in addition meets NDE necessities 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 lowering operational dangers and the related prices to fulfill stringent environmental and well being and safety objectives. Finally, there might be เกจวัดแรงดันปั๊มลมpuma monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and safety against dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to assist and preserve and no supporting techniques, the latest magnetic drive sealless pump technology presents important security, cost and operational advantages. Lower end-user set up prices and simplified upkeep requirements, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
