Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring 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 utility which poses explicit challenges to course of operators, including the dangers related to the dealing with of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the broader surroundings ought to leaks happen.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a critical safety component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of unpolluted fuels’ legislation has elevated the demand for alkylate, which is also 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 well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in cast steel components that will in the end cut back the life of pumps, valves and other gear and worse still, end in product leakage. เกจวัดแรงดันน้ําไทวัสดุ -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations nice importance on the selection of fabric of forged parts, notably in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly 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 results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive growth course of, the HMD Kontro HF pump features 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 options
Built into the design of those next generation pumps are options which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and likewise 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 setting, and reducing operational risks and the associated costs to satisfy stringent environmental and well being and security targets. Finally, there’s continuous monitoring to make sure a reliable 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 techniques to help and keep and no supporting methods, the newest magnetic drive sealless pump expertise provides vital security, cost and operational advantages. Lower end-user set up prices and simplified upkeep requirements, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
