Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to process operators, including the dangers related to the dealing with of a lethal, highly corrosive fluid which poses a potential hazard to plant tools, the people who work on site and the wider environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a important safety part that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ laws has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in modern autos.
Potential dangers
The HF alkylation process poses a selection of severe environmental and well being and safety dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in cast metallic parts that may in the end cut back the life of pumps, valves and different gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places nice importance on the choice of fabric of solid components, significantly when it comes to the pump casing and impeller.
Designed for เกจวัดแรงดันปั๊มลมpuma in opposition to highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed for use in hydrofluoric acid alkylation models and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The result of shut collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an revolutionary improvement process, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of these subsequent era pumps are features which meet operator-specific needs for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been confirmed to offer the required 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 surroundings, and lowering operational risks and the related costs to satisfy stringent environmental and well being and safety targets. Finally, there may be continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection against dry pump working (power management monitor).
With no seals to leak, no seal buffer techniques to support and maintain and no supporting systems, the most recent magnetic drive sealless pump expertise provides important safety, cost and operational benefits. Lower end-user installation costs and simplified maintenance necessities, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
