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 software which poses particular challenges to process operators, including the risks associated with the handling of a deadly, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on web site and the wider setting ought to leaks happen.
The process
HF Alkylation combines olefins (primarily a combination 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 security part that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has increased the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
ราคาpressuregauge of poses a selection of critical environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in forged steel components that can in the end scale back the life of pumps, valves and other equipment and worse still, result in 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 solid components, notably in phrases of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been specifically designed for use 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 leading licensor of HF alkylation technology 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 examined using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent technology pumps are features which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been proven to offer the necessary resistance to corrosion and also meets NDE necessities 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 environment, and reducing operational dangers and the associated prices to satisfy stringent environmental and health and safety targets. Finally, there may be steady monitoring to make sure a dependable 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 methods to assist and preserve and no supporting methods, the most recent magnetic drive sealless pump know-how presents important safety, value and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
