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 dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to process operators, together with the risks associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on website and the wider setting ought to leaks occur.
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 produce alkylate. A high-octane additive, alkylate is a important safety component that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in modern 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 equipment corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in solid steel parts that may ultimately scale back the life of pumps, valves and different tools and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations great importance on the choice of material of solid parts, significantly by method of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids such as HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation units and had been 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 innovative development 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 generation pumps are options which meet operator-specific needs for the HF alkylation course of. เกจวัดแรงดันน้ำมันเบนซิน include a pump casing in Alloy C22 supplies, which has been proven to supply the mandatory resistance to corrosion and in addition meets NDE requirements 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 environment, and decreasing operational risks and the related costs to fulfill stringent environmental and health and safety targets. Finally, there may be continuous monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and safety towards dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to assist and preserve and no supporting methods, the most recent magnetic drive sealless pump technology offers vital security, cost and operational advantages. Lower end-user set up costs and simplified maintenance requirements, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
