Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new applied sciences, particularly 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 utility which poses explicit challenges to process operators, including the dangers associated with the handling of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on 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 produce alkylate. A high-octane additive, alkylate is a critical safety part that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
เกจวัดแก๊ส of poses a number of critical environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and attacks imperfections in forged metal parts that may finally reduce the lifetime of pumps, valves and other tools and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice importance on the selection of material of solid elements, particularly when it comes to the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation units 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 leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an revolutionary improvement course of, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent technology pumps are features which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to supply 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 for leakage into the surroundings, and decreasing operational risks and the associated prices to fulfill stringent environmental and well being and security objectives. Finally, there’s continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety in opposition to dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to assist and maintain and no supporting methods, the most recent magnetic drive sealless pump technology provides vital safety, price and operational advantages. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
