Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses explicit challenges to process operators, together with the risks associated with the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant tools, the people who work on site and the broader setting ought to leaks happen.
HF Alkylation combines olefins (primarily a mixture 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 element that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
The HF alkylation course of poses numerous severe environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in solid steel elements that can ultimately cut back the life of pumps, valves and other 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 nice significance on the selection of material of forged parts, particularly by means of the pump casing and impeller.
Designed for pressure gauge ลม against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used 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 shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and using an revolutionary development course of, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent era pumps are features which meet operator-specific needs for the HF alkylation process. They include a pump casing in Alloy C22 supplies, which has been proven to supply the necessary resistance to corrosion and likewise meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential for leakage into the surroundings, and decreasing operational risks and the associated prices to fulfill stringent environmental and health and safety targets. Finally, there is continuous monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and protection towards dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting systems, the latest magnetic drive sealless pump technology presents vital security, price and operational benefits. Lower end-user set up prices and simplified maintenance necessities, make it an effective whole-life proposition in comparability with standard mechanically sealed pumps.
