Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses explicit challenges to process operators, together with the risks related to the handling of a lethal, highly corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on website and the wider environment should leaks happen.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a critical security element 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’ legislation has increased the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
หลักการทํางานของpressuregauge poses numerous critical environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and attacks imperfections in forged steel parts that may in the end cut back the life 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 great significance on the choice of fabric of cast components, particularly by way of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of dealing with 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 utilizing an progressive development process, the HMD Kontro HF pump contains a excessive 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 features
Built into the design of those next technology pumps are features which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory 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 for leakage into the setting, and decreasing operational risks and the associated prices to fulfill stringent environmental and health and safety objectives. Finally, there may be steady monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and protection against dry pump operating (power control monitor).
With no seals to leak, no seal buffer methods to assist and preserve and no supporting systems, the newest magnetic drive sealless pump know-how offers significant safety, value and operational advantages. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
