Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to course of operators, including the dangers associated with the handling of a deadly, extremely corrosive fluid which poses a possible hazard to plant gear, the individuals who work on web site and the broader setting should leaks happen.
The process
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 part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can additionally be answerable for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential risks
The HF alkylation process poses a variety of critical environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. เพชเชอร์เกจ by its nature seeks out and attacks imperfections in solid metallic elements that may ultimately reduce the lifetime of pumps, valves and different equipment and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great significance on the choice of material of cast parts, significantly in phrases of the pump casing and impeller.
Designed for resistance in opposition to extremely 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 for use in hydrofluoric acid alkylation units 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 main licensor of HF alkylation know-how and HMD Kontro, and utilizing an revolutionary growth process, the HMD Kontro HF pump includes a high 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 features
Built into the design of those next era pumps are options which meet operator-specific needs for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been confirmed to supply the required resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the potential of leakage into the surroundings, and reducing operational risks and the related prices to fulfill stringent environmental and health and safety goals. Finally, there’s continuous monitoring to ensure a reliable sealless pump efficiency which includes leak detection instrumentation and protection towards dry pump running (power control monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting systems, the latest magnetic drive sealless pump know-how provides important security, cost and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparison with standard mechanically sealed pumps.
