Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses explicit challenges to process operators, together with the dangers associated with the dealing with of a lethal, extremely corrosive fluid which poses a possible hazard to plant equipment, the individuals who work on web site and the wider surroundings ought to leaks occur.
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 supply alkylate. A high-octane additive, alkylate is a crucial security element that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which can be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy autos.
Potential dangers
The HF alkylation process poses numerous serious environmental and health and security risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in cast metal parts that can finally scale back the life of pumps, valves and other gear 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 selection of fabric of cast elements, notably by means of the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences 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 technology and HMD Kontro, and using an progressive growth process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined using new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next era pumps are features which meet operator-specific needs for the HF alkylation process. เกจวัดแรงดันco2 include a pump casing in Alloy C22 supplies, which has been proven to offer 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 forty bar (580 psi), eliminating the potential for leakage into the environment, and decreasing operational dangers and the related prices to fulfill stringent environmental and health and safety targets. Finally, there is continuous monitoring to ensure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety in opposition to dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting techniques, the most recent magnetic drive sealless pump know-how provides significant safety, price and operational benefits. Lower end-user set up costs and simplified upkeep necessities, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
