Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of operators, including the dangers associated with the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on site and the wider setting ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a mixture 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 security element that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has elevated the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation process poses a selection of critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. pressure gauge น้ำมัน by its nature seeks out and assaults imperfections in solid metal elements that may in the end cut back the life of pumps, valves and different tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of material of forged components, significantly by method of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use in hydrofluoric acid alkylation models and have been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive development course of, the HMD Kontro HF pump includes a high 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 features
Built into the design of those subsequent era pumps are options 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 necessary resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential for leakage into the setting, and decreasing operational dangers and the related costs to satisfy stringent environmental and health and safety goals. Finally, there’s continuous monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection against dry pump working (power management monitor).
With no seals to leak, no seal buffer techniques to support and maintain and no supporting systems, the latest magnetic drive sealless pump technology presents vital security, value and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
