Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to course of operators, together with the risks associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant tools, the individuals who work on web site and the broader surroundings ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. เกจวัดแรงดัน300psi -octane additive, alkylate is a important security part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential risks
The HF alkylation course of poses numerous critical environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in cast metallic parts that can ultimately cut back the life of pumps, valves and different gear and worse still, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of fabric of forged parts, particularly when it comes to the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed to be used in hydrofluoric acid alkylation models 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 technology and HMD Kontro, and utilizing an innovative development process, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next generation pumps are features which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to supply the mandatory 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 potential for leakage into the setting, and decreasing operational risks and the related costs to satisfy stringent environmental and health and safety objectives. Finally, there could be continuous monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to assist and maintain and no supporting methods, the newest magnetic drive sealless pump know-how presents vital security, price and operational benefits. Lower end-user set up costs and simplified upkeep necessities, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
