Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps featuring new technologies, specifically designed to be used 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 process operators, including the risks related to the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on website and the broader setting should leaks happen.
The course of

HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important safety part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential dangers

The HF alkylation course of poses a quantity of severe environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in cast steel elements that can finally cut back the life of pumps, valves and other gear and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places great significance on the choice of material of forged components, notably in phrases of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed to be used in hydrofluoric acid alkylation models and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump

The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an progressive growth process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).

Built into the design of those next generation pumps are features which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to supply the required 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 of leakage into the surroundings, and decreasing operational dangers and the associated prices to meet stringent environmental and health and safety goals. Finally, there’s continuous monitoring to make sure a reliable sealless pump efficiency which incorporates leak detection instrumentation and safety towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer systems to assist and maintain and no supporting systems, the most recent magnetic drive sealless pump technology offers important security, cost and operational advantages. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
