Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to course of operators, including the dangers associated with the dealing with of a deadly, highly corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the wider environment should leaks happen.
The process
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 critical security part 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 elevated the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of poses a variety of severe environmental and well being and security dangers 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 forged metallic elements that may in the end cut back the life of pumps, valves and different gear and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak harmful course of fluids. The aggressive and damaging nature of HF acid places nice significance on the selection of fabric of forged components, significantly in phrases of the pump casing and impeller.
Designed for resistance towards highly corrosive fluids such as HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed for use in hydrofluoric acid alkylation models and had been developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The results of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an revolutionary improvement process, the HMD Kontro HF pump includes 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 those subsequent era pumps are features which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been proven to offer the required resistance to corrosion and also meets NDE necessities for HF acid. In เกจวัดแรงดัน250bar , the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential for leakage into the setting, and reducing operational dangers and the associated prices to fulfill stringent environmental and well being and safety targets. Finally, there may be เกจวัดน้ำยาแอร์refco monitoring to make sure a reliable sealless pump performance which incorporates leak detection instrumentation and protection in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer techniques to help and preserve and no supporting techniques, the most recent magnetic drive sealless pump know-how offers important safety, value and operational benefits. Lower end-user set up costs and simplified upkeep requirements, make it an effective whole-life proposition compared to standard mechanically sealed pumps.
