Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to course of operators, together with the risks associated with the handling of a deadly, highly corrosive fluid which poses a potential hazard to plant equipment, the people who work on website and the wider surroundings should leaks happen.
เพรสเชอร์เกจ 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 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 fresh fuels’ legislation has increased the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation process poses a selection of critical environmental and well being 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 forged steel elements that may ultimately scale back the lifetime of pumps, valves and other equipment and worse still, result in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid locations nice significance on the choice of material of cast elements, significantly when it comes to the pump casing and impeller.
Designed for resistance against highly corrosive fluids similar to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed for use in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive development course of, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent technology pumps are options which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to supply the mandatory resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the chance of leakage into the environment, and reducing operational risks and the associated costs to satisfy stringent environmental and health and security objectives. Finally, there’s steady monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump operating (power control monitor).
With ไดอะแฟรม to leak, no seal buffer systems to help and maintain and no supporting methods, the latest magnetic drive sealless pump technology presents important safety, price and operational advantages. Lower end-user installation costs and simplified maintenance necessities, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
