Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of operators, including the risks related to the dealing with of a lethal, extremely corrosive fluid which poses a potential hazard to plant tools, the people who work on website and the broader environment ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a combination 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 high vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ legislation has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential dangers
The HF alkylation process poses a variety of severe environmental and health and security dangers 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 steel components that will ultimately reduce the lifetime of pumps, valves and different tools and worse nonetheless, end 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 choice of material of forged parts, particularly when it comes to the pump casing and impeller.
Designed for ไดอะแฟรม ซีล towards highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps offer whole containment with built-in reliability. pressure gauge 10 bar featuring new technologies have been specifically designed to be used in hydrofluoric acid alkylation units and were 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 know-how and HMD Kontro, and utilizing an revolutionary growth 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 methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those 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 offer the mandatory resistance to corrosion and likewise meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the risk of leakage into the surroundings, and decreasing operational risks and the related prices to fulfill stringent environmental and well being and safety goals. Finally, there might be continuous monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and protection towards dry pump operating (power management monitor).
With no seals to leak, no seal buffer techniques to assist and preserve and no supporting systems, the most recent magnetic drive sealless pump technology presents important security, cost and operational advantages. Lower end-user installation costs and simplified maintenance necessities, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
