Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, 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 application which poses specific challenges to course of operators, together with the risks associated with the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on site and the wider environment 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 supply alkylate. pressure gauge ด้าน ดูด -octane additive, alkylate is a important safety part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of 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. HF acid by its nature seeks out and attacks imperfections in solid metal parts that may in the end reduce the life of pumps, valves and different tools and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the selection of fabric of cast components, notably by method of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation items and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and utilizing an revolutionary 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 tested using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been confirmed to supply the necessary resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the surroundings, and decreasing operational dangers and the related costs to meet stringent environmental and well being and safety targets. Finally, there is continuous monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and safety towards dry pump running (power control monitor).
With no seals to leak, no seal buffer systems to support and keep and no supporting systems, the most recent magnetic drive sealless pump expertise offers important security, price and operational advantages. Lower end-user installation prices and simplified maintenance necessities, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
