Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new applied sciences, 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 application which poses particular challenges to process operators, together with the dangers associated with the handling of a deadly, highly corrosive fluid which poses a possible hazard to plant tools, the individuals who work on site and the broader setting 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. A high-octane additive, alkylate is a critical safety part that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ laws has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential risks
The HF alkylation course of poses numerous severe environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF release. เกจวัดแรงดันแก๊ส by its nature seeks out and assaults imperfections in solid metallic components that can in the end reduce the lifetime of pumps, valves and other gear and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice significance on the selection of fabric of cast elements, notably in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. ราคาpressuregauge featuring new applied sciences have been specifically designed for use in hydrofluoric acid alkylation items and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close 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 tested utilizing 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 process. They include a pump casing in Alloy C22 materials, which has been confirmed 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 forty bar (580 psi), eliminating the potential for leakage into the setting, and decreasing operational dangers and the associated prices to meet stringent environmental and health and safety objectives. Finally, there is continuous monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to help and keep and no supporting methods, the latest magnetic drive sealless pump expertise provides significant safety, price and operational benefits. Lower end-user installation costs and simplified maintenance requirements, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
