Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to course of operators, including the dangers related to the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on website and the broader setting ought to 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 crucial security element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of clean fuels’ laws has increased the demand for alkylate, which can also be answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential risks
The HF alkylation process poses a quantity of severe environmental and well being and security dangers 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 solid metallic components that may in the end cut back the life of pumps, valves and other tools and worse still, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of material of cast components, notably in phrases of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation units and were developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut 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 examined utilizing new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent era pumps are options which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been confirmed to supply the necessary resistance to corrosion and in addition meets NDE necessities for HF acid. In เกจวัดแรงดันน้ำมันเครื่อง , the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the possibility of leakage into the setting, and lowering operational risks and the associated prices to satisfy stringent environmental and health and safety objectives. Finally, there is continuous monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and safety in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to help and keep and no supporting techniques, the latest magnetic drive sealless pump technology provides vital security, value and operational advantages. Lower end-user installation prices and simplified upkeep requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
