Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses explicit challenges to course of operators, including the dangers associated with the handling of a deadly, highly corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on website and the wider surroundings 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 important security component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ laws has increased the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential dangers
The HF alkylation process poses numerous serious environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in cast steel parts that will in the end reduce the lifetime of pumps, valves and different gear and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of fabric of cast parts, significantly by method of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. เกจวัดแรงดันน้ำดิจิตอล featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation items and had been 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 expertise and HMD Kontro, and utilizing an innovative development process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent generation pumps are options which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been confirmed to offer the mandatory 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 possibility of leakage into the environment, and decreasing operational dangers and the related prices to fulfill stringent environmental and well being and security targets. Finally, there might be continuous monitoring to ensure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety against dry pump operating (power management monitor).
With no seals to leak, no seal buffer techniques to assist and keep and no supporting methods, the latest magnetic drive sealless pump know-how offers important security, cost and operational benefits. Lower end-user installation prices and simplified upkeep requirements, make it an efficient whole-life proposition in comparison with standard mechanically sealed pumps.
