Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, including the risks associated with the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant tools, the people who work on site and the wider setting ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a important security element that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential dangers
The HF alkylation process poses numerous critical environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in cast metal parts that can finally scale back the lifetime of pumps, valves and different tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of material of forged elements, particularly in terms of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed to be used in hydrofluoric acid alkylation units and have 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 know-how and HMD Kontro, and using an revolutionary 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 strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent technology pumps are features which meet operator-specific wants for the HF alkylation process. เกจวัดแรงอัดกระบอกสูบ include a pump casing in Alloy C22 materials, which has been proven to offer 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 surroundings, and reducing operational risks and the associated prices to meet stringent environmental and well being and security objectives. Finally, there could be steady monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer systems to help and preserve and no supporting systems, the newest magnetic drive sealless pump expertise offers important safety, value and operational advantages. Lower end-user installation prices and simplified upkeep requirements, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
