Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, particularly designed to be used in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, together with the risks related to the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on web site and the wider setting ought to leaks happen.
The process

HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important security component that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ laws has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
pressure gauge ด้าน ดูด poses a quantity of critical 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 attacks imperfections in solid metallic components that can in the end scale back the lifetime of pumps, valves and other tools and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of material of forged components, notably in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation items and were 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 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 using new methods of Non-Destructive Examination (NDE).
Specialist design options

Built into the design of those next generation pumps are options which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to offer the necessary resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the chance of leakage into the surroundings, and reducing operational risks and the related prices to satisfy stringent environmental and health and safety targets. Finally, there is steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety towards dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to help and keep and no supporting methods, the latest magnetic drive sealless pump expertise presents important security, cost and operational benefits. Lower end-user set up costs and simplified upkeep necessities, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
