Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to process operators, together with the risks associated with the dealing with of a lethal, highly corrosive fluid which poses a possible hazard to plant equipment, the people who work on website and the wider environment should leaks happen.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a critical security component that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of fresh fuels’ laws has elevated the demand for alkylate, which can be answerable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential dangers
The HF alkylation course of poses numerous severe environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in forged steel parts that can in the end scale back the lifetime of pumps, valves and different tools and worse still, end in product leakage. เครื่องมือที่ใช้วัดความดันโลหิต -prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of material of solid parts, particularly by way of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids such as HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation items and had 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 technology and HMD Kontro, and using an progressive improvement course of, the HMD Kontro HF pump features a excessive 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 features
Built into the design of these next era pumps are options which meet operator-specific needs for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been confirmed to offer the necessary resistance to corrosion and likewise meets NDE necessities 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 setting, and reducing operational dangers and the associated prices to meet stringent environmental and well being and security targets. Finally, there is เกวัดแรงดันน้ำ monitoring to ensure a reliable sealless pump performance which incorporates leak detection instrumentation and protection towards dry pump operating (power control monitor).
With no seals to leak, no seal buffer techniques to support and preserve and no supporting methods, the latest magnetic drive sealless pump know-how provides significant security, cost and operational benefits. Lower end-user set up prices and simplified maintenance requirements, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
