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, extremely corrosive fluid which poses a possible hazard to plant gear, the individuals who work on site and the wider environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a crucial safety part that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ laws has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
เกจวัดแรงดันน้ำราคา of poses a selection of serious environmental and well being and security 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 metal components that may ultimately reduce the life of pumps, valves and different equipment and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great importance on the selection of material of solid elements, notably when it comes to the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly designed for use in hydrofluoric acid alkylation items and have 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 know-how and HMD Kontro, and using 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 using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent technology pumps are options which meet operator-specific wants for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been confirmed to supply the required resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the risk of leakage into the environment, and decreasing operational dangers and the associated costs to satisfy stringent environmental and well being and security objectives. Finally, there might be steady monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and safety against dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting systems, the latest magnetic drive sealless pump know-how provides significant safety, value and operational benefits. Lower end-user set up costs and simplified maintenance requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
