Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of 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 website and the broader surroundings ought to leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a critical safety component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ laws has increased the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential dangers
The HF alkylation process poses numerous critical environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in forged metallic components that will ultimately reduce the life of pumps, valves and different equipment and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of material of cast components, significantly when it comes to the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide 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 were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an progressive growth course of, the HMD Kontro HF pump features 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 these subsequent era pumps are features which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been confirmed to offer the required resistance to corrosion and likewise meets NDE necessities 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 setting, and reducing operational risks and the related costs to meet stringent environmental and well being and safety targets. Finally, there’s steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety against dry pump running (power control monitor).
With เกจวัดแรงดันไนโตรเจนราคา to leak, no seal buffer techniques to support and keep and no supporting techniques, the newest magnetic drive sealless pump know-how presents significant security, value and operational advantages. Lower end-user installation prices and simplified upkeep requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
