Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, including the risks associated with the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on web site and the broader surroundings should leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a crucial security element that offsets the high vapour pressure 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 can also be answerable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential risks
The HF alkylation process poses a variety of serious environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF launch. เกจวัดco2 by its nature seeks out and assaults imperfections in forged steel components that may ultimately cut back the lifetime of pumps, valves and other gear and worse nonetheless, 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 fabric of cast elements, significantly by means of the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed to be used in hydrofluoric acid alkylation models and have been developed in response to the challenges of dealing with 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 revolutionary development course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent era pumps are options 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 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 risk of leakage into the environment, and lowering operational risks and the associated prices to meet stringent environmental and well being and security goals. Finally, there is steady monitoring to ensure a dependable sealless pump efficiency which includes leak detection instrumentation and protection in opposition to dry pump working (power control monitor).
With no seals to leak, no seal buffer systems to help and preserve and no supporting methods, the latest magnetic drive sealless pump expertise presents significant security, cost and operational benefits. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
