Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to process operators, together with the dangers related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant gear, the individuals who work on website and the broader surroundings should leaks occur.
เครื่องมือที่ใช้ในการวัดความดัน of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important security element that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can additionally be responsible for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential dangers
The HF alkylation course of poses a quantity of critical environmental and health and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in forged metallic elements that can in the end scale back the life of pumps, valves and different gear and worse still, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations great significance on the choice of fabric of cast components, particularly by method of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide total containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation units and were developed in response to the challenges of dealing with HF acid.

HMD Kontro HF pump
The result of close collaboration between UOP Honeywell, the main licensor of HF alkylation know-how and HMD Kontro, and using an progressive improvement course of, the HMD Kontro HF pump includes 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 features
Built into the design of these next era pumps are features which meet operator-specific wants for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to supply the necessary resistance to corrosion and likewise 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 associated costs to fulfill stringent environmental and health and safety targets. Finally, there’s continuous monitoring to make sure a reliable sealless pump performance which includes leak detection instrumentation and safety towards dry pump working (power management monitor).
With no seals to leak, no seal buffer methods to assist and keep and no supporting methods, the newest magnetic drive sealless pump technology offers significant security, cost and operational advantages. Lower end-user set up prices and simplified upkeep necessities, make it an effective whole-life proposition compared to typical mechanically sealed pumps.
