Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses specific challenges to process operators, together with the risks related to the handling of a deadly, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on site and the broader setting should leaks happen.
The course of

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 crucial security element that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in trendy vehicles.
Potential risks

The HF alkylation course of poses a variety of severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in forged metal elements that can finally scale back the life of pumps, valves and other tools and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of material of forged components, notably when it comes to the pump casing and impeller.
Designed for digital pressure gauge against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. ไดอะแฟรม ซีล that includes new applied sciences have been particularly designed to be used in hydrofluoric acid alkylation units 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 expertise and HMD Kontro, and using an revolutionary improvement course of, the HMD Kontro HF pump features a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been examined utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design options

Built into the design of those subsequent technology pumps are features which meet operator-specific wants for the HF alkylation process. They embody a pump casing in Alloy C22 materials, which has been confirmed to supply the mandatory resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the possibility of leakage into the environment, and decreasing operational risks and the related costs to satisfy stringent environmental and health and safety goals. Finally, there may be steady monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and safety against dry pump running (power control monitor).
With no seals to leak, no seal buffer systems to assist and keep and no supporting methods, the most recent magnetic drive sealless pump know-how presents significant safety, value and operational benefits. Lower end-user installation prices and simplified maintenance requirements, make it an efficient whole-life proposition in comparison with conventional mechanically sealed pumps.
