Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, specifically 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 specific challenges to process operators, including the risks associated with the dealing with of a deadly, highly corrosive fluid which poses a possible hazard to plant gear, the people who work on site and the wider environment should leaks occur.
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 produce alkylate. A high-octane additive, alkylate is a critical security part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ laws has increased the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential dangers
The HF alkylation course of poses a quantity of serious environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. เกจวัดแรงดันไนโตรเจน by its nature seeks out and assaults imperfections in forged steel components that can finally scale back the lifetime of pumps, valves and other equipment and worse still, result in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of fabric of forged elements, particularly in terms of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids corresponding 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 items and had been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and utilizing an revolutionary development 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 new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next technology pumps are features which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been confirmed to supply the required resistance to corrosion and likewise 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 environment, and decreasing operational dangers and the related prices to fulfill stringent environmental and well being and safety objectives. Finally, there’s steady monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and safety towards dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to support and maintain and no supporting methods, the most recent magnetic drive sealless pump expertise offers important safety, cost and operational advantages. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
