Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to course of operators, including the risks related to the dealing with of a deadly, extremely corrosive fluid which poses a possible hazard to plant gear, the individuals who work on website and the broader environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mixture 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 excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has elevated the demand for alkylate, which can be answerable for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential dangers
The HF alkylation process poses a number of severe environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in forged metallic elements that will ultimately reduce the life of pumps, valves and different gear and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places nice importance on the selection of material of forged parts, significantly when it comes to the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed for use in hydrofluoric acid alkylation units and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and utilizing an revolutionary improvement process, the HMD Kontro HF pump features 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 those subsequent era pumps are features which meet operator-specific needs for the HF alkylation process. เกจวัดแรงดัน embody a pump casing in Alloy C22 supplies, which has been confirmed to offer the required resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential for leakage into the surroundings, and lowering operational dangers and the associated prices to meet stringent environmental and well being and security goals. Finally, there is steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety against dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to assist and preserve and no supporting techniques, the newest magnetic drive sealless pump know-how offers vital safety, cost and operational benefits. Lower end-user set up costs and simplified upkeep necessities, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
