Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, including the risks associated with the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on web site and the wider environment should leaks happen.
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 important safety component that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential risks
The HF alkylation process poses a number of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. เกจวัดแรงดัน by its nature seeks out and attacks imperfections in solid steel components that can ultimately scale back the life of pumps, valves and other tools and worse still, 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 in terms of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide complete 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 items and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and utilizing an progressive 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 features
Built into the design of those subsequent era pumps are options which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been proven to offer 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 chance of leakage into the setting, and lowering operational risks and the related costs to meet stringent environmental and well being and safety goals. Finally, there’s continuous monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and safety against dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to help and keep and no supporting techniques, the latest magnetic drive sealless pump expertise offers important safety, value and operational advantages. Lower end-user set up costs and simplified upkeep requirements, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
