Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to course of operators, including the dangers associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the broader setting should leaks happen.
The course of

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 important safety element that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential risks

The HF alkylation process poses a variety of severe environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in solid steel elements that can ultimately cut back the life of pumps, valves and other gear and worse still, result in product leakage. pressure gauge octa -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of material of cast elements, notably in terms of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use 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 close collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and using an innovative growth process, the HMD Kontro HF pump includes a excessive 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 options

Built into the design of these subsequent generation pumps are options which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been confirmed to supply the necessary 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 surroundings, and lowering operational dangers and the associated costs to meet stringent environmental and health and safety objectives. Finally, there’s continuous monitoring to ensure a dependable sealless pump performance which includes leak detection instrumentation and protection towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting techniques, the newest magnetic drive sealless pump technology presents significant security, value and operational advantages. digital pressure gauge -user installation costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
