Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses particular challenges to course of operators, together with the risks related to the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant equipment, the people who work on website and the broader surroundings should leaks happen.
The course of
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in 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 continuous tightening of clean fuels’ legislation has elevated the demand for alkylate, which can also be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation process poses a variety of critical environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and assaults imperfections in solid steel elements that may in the end cut back the life of pumps, valves and other equipment and worse still, result in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice importance on the selection of material of solid parts, particularly by method of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids similar to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly 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 result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation technology and HMD Kontro, and using an innovative growth course of, the HMD Kontro HF pump includes a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those subsequent era pumps are options which meet operator-specific needs for the HF alkylation course of. pressure gauge น้ำ embrace a pump casing in Alloy C22 materials, which has been proven to supply the necessary 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 possibility of leakage into the environment, and decreasing operational risks and the associated prices to meet stringent environmental and well being and security targets. Finally, there could be steady monitoring to ensure a dependable sealless pump performance which includes leak detection instrumentation and safety against dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to help and maintain and no supporting methods, the most recent magnetic drive sealless pump expertise offers significant safety, value and operational advantages. Lower end-user set up prices and simplified upkeep requirements, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
