Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses explicit challenges to course of operators, together with the risks associated with the dealing with of a lethal, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the wider setting should leaks happen.
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 provide alkylate. A high-octane additive, alkylate is a critical safety component that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can be liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
เพรสเชอร์เกจ of poses a number of critical 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 assaults imperfections in cast metallic components that can ultimately cut back the lifetime of pumps, valves and different equipment and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations nice importance on the choice of material of forged elements, significantly when it comes to the pump casing and impeller.
Designed for pressure gauge against highly 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 items and had been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump

The results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an innovative improvement process, the HMD Kontro HF pump contains a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new methods of Non-Destructive Examination (NDE).
Specialist design features

Built into the design of these subsequent technology 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 necessary 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 of leakage into the setting, and reducing operational dangers and the associated costs to meet stringent environmental and well being and security goals. Finally, there could be steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and safety against dry pump working (power control monitor).
With no seals to leak, no seal buffer systems to help and keep and no supporting methods, the most recent magnetic drive sealless pump expertise offers significant safety, value and operational benefits. Lower end-user installation prices and simplified maintenance necessities, make it an effective whole-life proposition in comparability with typical mechanically sealed pumps.
