Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, particularly designed for use 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 application which poses specific challenges to process operators, together with the risks related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the wider surroundings should leaks happen.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. pressure gauge ราคา ถูก -octane additive, alkylate is a critical security component that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ laws has increased the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential dangers
The HF alkylation course of poses numerous severe environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in solid metal components that can finally cut back the lifetime of pumps, valves and other equipment and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places great importance on the selection of material of solid parts, particularly in phrases of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use 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 shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an progressive growth course of, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using เกจวัดแรงดันลมดิจิตอล of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent generation pumps are features which meet operator-specific needs for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply the mandatory resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential of leakage into the setting, and reducing operational dangers and the related prices to fulfill stringent environmental and well being and safety objectives. Finally, there is steady monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer techniques to support and maintain and no supporting techniques, the newest magnetic drive sealless pump know-how provides vital security, cost and operational advantages. Lower end-user installation costs and simplified upkeep requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
