Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to process operators, including the risks related to the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on web site and the wider setting ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important safety component that offsets the high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential dangers
The HF alkylation course of poses a number of critical environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in solid metallic parts that may finally scale back the lifetime of pumps, valves and different tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations great significance on the selection of fabric of forged components, particularly by method of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as 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 models and had 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 utilizing an innovative improvement process, the HMD Kontro HF pump includes 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 features
Built into the design of these next era pumps are features which meet operator-specific wants for the HF alkylation course of. They embody a pump casing in Alloy C22 materials, which has been confirmed to offer the necessary 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 for leakage into the environment, and lowering operational risks and the related costs to satisfy stringent environmental and health and security objectives. Finally, there may be เครื่องมือที่ใช้ในการวัดความดัน monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to support and maintain and no supporting methods, the most recent magnetic drive sealless pump technology provides important security, cost and operational advantages. Lower end-user set up costs and simplified upkeep necessities, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
