Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to process operators, together with the risks associated with the dealing with of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the wider surroundings should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a critical safety component 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 increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential risks
The HF alkylation process poses a variety of severe 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 forged metallic elements that may in the end reduce the lifetime of pumps, valves and different gear and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places great importance on the choice of material of forged parts, significantly by way of the pump casing and impeller.
Designed for เพชเชอร์เกจ against extremely corrosive fluids such as HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation items and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive development process, the HMD Kontro HF pump contains a high 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 features
Built into the design of those subsequent era pumps are features which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply 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 of leakage into the surroundings, and lowering operational dangers and the related prices to satisfy stringent environmental and health and security targets. Finally, there’s steady monitoring to ensure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety in opposition to dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to support and keep and no supporting techniques, the most recent magnetic drive sealless pump expertise offers significant security, cost and operational advantages. Lower end-user installation costs and simplified maintenance requirements, make it an efficient whole-life proposition in comparability with standard mechanically sealed pumps.
