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 handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to process operators, including the dangers related to the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on web site and the wider surroundings should leaks happen.
The course of
HF Alkylation combines olefins (primarily a mixture 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 part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential dangers
The HF alkylation process poses a quantity of serious environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. เกจวัดแรงดันปั๊มลมpuma by its nature seeks out and attacks imperfections in forged metal components that will ultimately cut back the lifetime of pumps, valves and other equipment and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations nice importance on the selection of fabric of solid components, significantly by method of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation items and were 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 expertise and HMD Kontro, and using an innovative growth process, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent era pumps are features which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been proven to supply 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 possibility of leakage into the setting, and lowering operational dangers and the related costs to meet stringent environmental and health and safety targets. Finally, there might be steady monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and safety against dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to support and maintain and no supporting techniques, the newest magnetic drive sealless pump expertise presents vital safety, cost and operational benefits. Lower end-user installation prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
