Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to course of operators, including the dangers associated with the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant tools, the individuals who work on web site and the broader environment should leaks happen.
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 critical security part that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ legislation has increased the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation course of poses numerous critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in solid metal elements that will in the end reduce the life of pumps, valves and different tools and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations great significance on the choice of fabric of forged parts, notably by method of the pump casing and impeller.
Designed for weksler ea14 towards extremely corrosive fluids such as 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 items and have been developed in response to the challenges of handling 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 growth process, the HMD Kontro HF pump includes a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new methods of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of these subsequent era pumps are features which meet operator-specific wants for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been proven 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 forty bar (580 psi), eliminating the risk of leakage into the surroundings, and reducing operational risks and the associated costs to fulfill stringent environmental and health and security targets. Finally, there’s steady monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting systems, the most recent magnetic drive sealless pump expertise provides vital security, cost and operational benefits. Lower end-user set up prices and simplified upkeep requirements, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
