Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to course of operators, including the risks related to the handling of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on site and the broader environment ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a critical security part that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation course of poses a selection of critical environmental and health and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in cast metal parts that will in the end cut back the life of pumps, valves and different equipment and worse nonetheless, result in product leakage. pressure gauge แบบ น้ำมัน -prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places great significance on the choice of fabric of cast elements, notably in terms of the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation models and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an innovative improvement 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 methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent generation pumps are options which meet operator-specific needs for the HF alkylation course of. They embrace 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 40 bar (580 psi), eliminating the potential for leakage into the environment, and reducing operational dangers and the related prices to fulfill stringent environmental and health and security targets. Finally, there’s continuous monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and protection 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 newest magnetic drive sealless pump expertise presents vital safety, value and operational benefits. Lower end-user installation prices and simplified maintenance necessities, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
