Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, 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, together with the risks related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant gear, the people who work on web site and the wider environment ought to leaks happen.
The process

HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important safety part that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which can also be liable for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential risks

The HF alkylation process poses a variety of serious environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. เกจแรงดันลม by its nature seeks out and attacks imperfections in cast metallic parts that may ultimately scale back the life of pumps, valves and other equipment and worse still, result in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of material of forged parts, notably by means of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed to be used in hydrofluoric acid alkylation models and have 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 leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an progressive 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 utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features

Built into the design of those next technology pumps are options which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and in addition 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 environment, and decreasing operational risks and the related costs to fulfill stringent environmental and health and security goals. Finally, there could be continuous monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump working (power control monitor).
With no seals to leak, no seal buffer techniques to assist and keep and no supporting techniques, the most recent magnetic drive sealless pump know-how presents vital safety, value and operational advantages. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparability with standard mechanically sealed pumps.
