Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses explicit challenges to process operators, including the dangers related to the dealing with of a deadly, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on 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 supply alkylate. A high-octane additive, alkylate is a important security part that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ laws has elevated the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential dangers
The HF alkylation course of poses numerous serious environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in cast steel components that may in the end scale back the lifetime of pumps, valves and other gear and worse nonetheless, end in product leakage. Hilarious -prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places great importance on the choice of fabric of solid components, significantly in terms of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation units and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation know-how and HMD Kontro, and utilizing an revolutionary growth course of, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using 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 course of. They embody a pump casing in Alloy C22 supplies, which has been confirmed to supply the required 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 of leakage into the surroundings, and lowering operational dangers and the associated costs to meet stringent environmental and health and security objectives. Finally, there may be steady monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and safety against dry pump running (power control monitor).
With no seals to leak, no seal buffer techniques to help and keep and no supporting systems, the newest magnetic drive sealless pump know-how provides significant security, price and operational advantages. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition in comparability with standard mechanically sealed pumps.
