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 utility which poses explicit challenges to process operators, together with the dangers related to the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the broader setting should leaks happen.

HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a crucial security component that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential risks
The HF alkylation course of poses a selection of severe environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in forged steel elements that will in the end reduce the life of pumps, valves and other tools and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places great significance on the choice of material of solid elements, particularly by means of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply 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 had been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an innovative development process, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been confirmed to offer the necessary resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the setting, and lowering operational dangers and the related prices to meet stringent environmental and health and security targets. Finally, there’s steady monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection against dry pump working (power management monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting methods, the most recent magnetic drive sealless pump technology presents vital security, value and operational benefits. Lower end-user set up costs and simplified maintenance necessities, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
