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 specific challenges to course of operators, together with the risks associated with the handling of a deadly, highly corrosive fluid which poses a possible hazard to plant gear, the people who work on site and the broader setting ought to leaks happen.
เพชเชอร์เกจ 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 security part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential risks
The HF alkylation process poses a selection of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in cast metal components that will finally cut back the life of pumps, valves and other tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the selection of material of forged components, significantly when it comes to the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use in hydrofluoric acid alkylation items and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive 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 examined using new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent technology pumps are features which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the setting, and reducing operational dangers and the related prices to satisfy stringent environmental and health and security targets. Finally, there’s steady monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety against dry pump operating (power management monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting systems, the newest magnetic drive sealless pump know-how presents vital safety, cost and operational benefits. Lower end-user set up prices and simplified upkeep requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
