Magnetic drive sealless pumps that includes new applied sciences, specifically designed to be used in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to process operators, including the dangers related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the wider environment should leaks occur.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. เครื่องมือที่ใช้วัดความดันเลือด -octane additive, alkylate is a critical safety part that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ laws has increased the demand for alkylate, which can also be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential dangers
The HF alkylation process poses a number of severe environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in solid steel parts that can finally reduce the life of pumps, valves and other gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the selection of fabric of solid elements, significantly when it comes to the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids such as HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation units and had 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 know-how and HMD Kontro, and using an progressive growth course of, the HMD Kontro HF pump contains 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 those subsequent generation pumps are options which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been confirmed to supply the required 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 potential for leakage into the surroundings, and reducing operational risks and the related prices to satisfy stringent environmental and well being and security targets. Finally, there is steady monitoring to make sure a reliable sealless pump efficiency which includes leak detection instrumentation and safety towards dry pump running (power management monitor).
With no seals to leak, no seal buffer techniques to support and keep and no supporting methods, the newest magnetic drive sealless pump know-how provides significant security, cost and operational benefits. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
