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 utility which poses specific challenges to course of operators, including the risks related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on web site and the wider setting should leaks occur.
The course of
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 important security component that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential risks
The HF alkylation course of poses numerous serious environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in cast metallic components that can ultimately cut back the lifetime of pumps, valves and different gear 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 nice importance on the choice of fabric of forged components, notably by means of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation models and have 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 progressive development process, the HMD Kontro HF pump includes a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these next technology pumps are features 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 required resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the risk of leakage into the environment, and decreasing operational dangers and the related costs to meet stringent environmental and health and safety objectives. Finally, there may be continuous monitoring to ensure a reliable sealless pump performance which includes leak detection instrumentation and protection against dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting systems, the most recent magnetic drive sealless pump know-how presents vital security, value and operational benefits. Lower end-user installation costs and simplified maintenance requirements, make it an effective whole-life proposition in comparability with typical mechanically sealed pumps.
