Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, including the dangers associated with the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on website and the broader environment should leaks happen.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. เกจวัดแรงดันไทวัสดุ -octane additive, alkylate is a important safety component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of unpolluted fuels’ laws has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of poses numerous critical environmental and health 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 forged metallic elements that may in the end reduce the lifetime of pumps, valves and different equipment 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 nice significance on the choice of material of forged elements, particularly in terms of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids such as HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed to be used in hydrofluoric acid alkylation models and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an innovative improvement process, the HMD Kontro HF pump contains a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent era pumps are options which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been confirmed to supply the required resistance to corrosion and also meets NDE necessities 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 reducing operational dangers and the associated costs to meet stringent environmental and well being and safety targets. Finally, there’s steady monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and protection towards dry pump working (power control monitor).
With no seals to leak, no seal buffer techniques to support and keep and no supporting techniques, the latest magnetic drive sealless pump know-how provides vital security, cost and operational advantages. Lower end-user set up costs and simplified upkeep requirements, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
