Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to course of operators, including the risks associated with the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on web site and the wider environment should leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture 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 security element that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential risks
The HF alkylation process poses numerous serious environmental and well being and security 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 assaults imperfections in forged metal parts that will ultimately reduce the lifetime of pumps, valves and different tools and worse still, 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 selection of material of forged parts, notably by means of the pump casing and impeller.
Designed for resistance in opposition to highly corrosive fluids such as HF acids, magnetic drive sealless pumps offer complete 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 were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an innovative growth course of, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next technology pumps are features which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 supplies, which has been proven to offer the necessary resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the risk of leakage into the environment, and lowering operational risks and the associated prices to satisfy stringent environmental and health and safety targets. Finally, there may be steady monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and protection in opposition to dry pump running (power control monitor).
With เพรสเชอร์เกจดิจิตอล to leak, no seal buffer techniques to support and maintain and no supporting systems, the newest magnetic drive sealless pump know-how offers important security, price and operational advantages. Lower end-user set up costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparison with conventional mechanically sealed pumps.
