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 application which poses specific challenges to process operators, together with the dangers associated with the dealing with of a lethal, 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.
The course of

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 element that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ legislation has elevated the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential risks

The HF alkylation course of poses a quantity of critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in cast steel elements that will ultimately reduce the lifetime of pumps, valves and different tools and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places great importance on the choice of fabric of solid components, notably when it comes to the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps provide total 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 have been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump

The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an innovative 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 strategies of Non-Destructive Examination (NDE).
Specialist design options

Built into the design of those subsequent generation pumps are features which meet operator-specific wants for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been confirmed to supply the required resistance to corrosion and also meets NDE necessities for HF acid. In เกจวัดแรงดันแก๊ส , the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential of leakage into the surroundings, and lowering operational risks and the associated prices to satisfy stringent environmental and health and safety objectives. Finally, there’s 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 newest magnetic drive sealless pump expertise presents significant safety, price and operational benefits. Lower end-user installation prices and simplified upkeep requirements, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
