Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, particularly designed for use 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 utility which poses explicit challenges to process operators, including the risks associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the people 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 provide alkylate. A high-octane additive, alkylate is a critical safety part that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ legislation has increased the demand for alkylate, which can also be responsible for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential dangers
The HF alkylation process poses a quantity of severe environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in forged 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 places great importance on the selection of material of cast parts, notably when it comes to the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use in hydrofluoric acid alkylation models and were 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 expertise and HMD Kontro, and using an revolutionary improvement 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 strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent technology pumps are options which meet operator-specific wants for the HF alkylation course of. เกจวัดco2 include a pump casing in Alloy C22 materials, which has been proven to supply the necessary resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the environment, and decreasing operational risks and the associated prices to meet stringent environmental and health and security objectives. Finally, there’s steady monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and protection against dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting systems, the latest magnetic drive sealless pump expertise offers vital safety, value and operational benefits. Lower end-user installation costs and simplified upkeep necessities, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
