Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, specifically 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 lethal, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the broader setting should leaks happen.
The course of
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 element that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ laws has increased the demand for alkylate, which can additionally be responsible for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential risks
The HF alkylation course of poses numerous serious environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. เกจ์วัดแรงดันลม by its nature seeks out and assaults imperfections in forged metallic components that may finally cut back the life of pumps, valves and different tools and worse nonetheless, 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 choice of material of cast elements, notably by way of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation units 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 innovative growth process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next technology pumps are features which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to offer the required resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential of leakage into the surroundings, and reducing operational risks and the associated costs to satisfy stringent environmental and well being and safety targets. Finally, there could be steady monitoring to make sure a reliable sealless pump efficiency which includes leak detection instrumentation and protection in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to assist and preserve and no supporting systems, the most recent magnetic drive sealless pump know-how presents significant security, cost and operational benefits. Lower end-user set up prices and simplified upkeep necessities, make it an efficient whole-life proposition in comparability with typical mechanically sealed pumps.
