Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application 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 people who work on website and the broader setting should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important security part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ laws has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
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 related HF release. HF acid by its nature seeks out and attacks imperfections in forged steel components that may in the end reduce the life of pumps, valves and other tools and worse still, result in product leakage. เกจวัดแรงดันลมคือ -prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice significance on the choice of material of forged parts, particularly in phrases of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids similar to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed for use 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 shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and utilizing an progressive development course of, 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 strategies of Non-Destructive Examination (NDE).
Built into the design of these next generation pumps are features which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and also meets NDE requirements 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 lowering operational risks and the associated costs to meet stringent environmental and health and security objectives. Finally, there is continuous monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and safety against dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting methods, the newest magnetic drive sealless pump know-how offers important safety, value and operational benefits. Lower end-user set up prices and simplified upkeep necessities, make it an efficient whole-life proposition compared to conventional mechanically sealed pumps.
