Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new technologies, 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 software which poses explicit challenges to course of operators, including the dangers associated with the dealing with of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the people who work on web site and the broader environment ought to leaks happen.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. เกจวัดแรงดัน1บาร์ -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 provides. The continuous tightening of fresh fuels’ laws has elevated the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential dangers
The HF alkylation course of poses a selection of serious environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in forged metal elements that will ultimately scale back the lifetime of pumps, valves and different tools and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of fabric of cast elements, significantly when it comes to the pump casing and impeller.
Designed for resistance against extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use in hydrofluoric acid alkylation units and had been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and utilizing an innovative development course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 materials, which has been confirmed to offer 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 forty bar (580 psi), eliminating the risk of leakage into the surroundings, and decreasing operational risks and the related costs to satisfy stringent environmental and health and safety goals. Finally, there’s continuous monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting systems, the latest magnetic drive sealless pump expertise provides important safety, price and operational advantages. Lower end-user set up costs and simplified maintenance requirements, make it an efficient whole-life proposition in comparability with typical mechanically sealed pumps.
