Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new technologies, specifically 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 explicit challenges to course of operators, including the dangers associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on web site and the broader environment ought to leaks happen.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a crucial safety part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ laws has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential dangers
The HF alkylation process poses numerous critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. เกจวัดแรงดันแก๊สหุงต้ม by its nature seeks out and attacks imperfections in forged metal components that can in the end scale back the lifetime of pumps, valves and other gear and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations nice importance on the choice of material of solid components, significantly in phrases of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed for use in hydrofluoric acid alkylation models and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of shut 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 excessive 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 technology pumps are options which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been confirmed to offer the mandatory resistance to corrosion and also meets NDE requirements 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 reducing operational risks and the associated costs to fulfill stringent environmental and health and safety objectives. Finally, there’s steady monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection towards dry pump operating (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting techniques, the most recent magnetic drive sealless pump technology provides vital safety, value and operational benefits. Lower end-user set up costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
