Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, including the dangers related to the dealing with of a deadly, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on site and the wider environment ought to leaks happen.
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 crucial safety component that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of unpolluted fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in modern automobiles.
Potential dangers
The HF alkylation course of poses numerous severe environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF release. HF acid by its nature seeks out and attacks imperfections in cast metal elements that may finally scale back the life of pumps, valves and different tools and worse still, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places nice significance on the choice of fabric of cast elements, significantly when it comes to the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids such as HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. เครื่องมือที่ใช้วัดความดันคือ that includes new technologies have been particularly designed to be used in hydrofluoric acid alkylation units and had been developed in response to the challenges of handling 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 innovative development course of, the HMD Kontro HF pump contains a excessive 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 features
Built into the design of these next technology pumps are features which meet operator-specific wants for the HF alkylation course of. They embody a pump casing in Alloy C22 supplies, which has been confirmed to offer the necessary resistance to corrosion and likewise meets NDE necessities 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 setting, and decreasing operational dangers and the associated prices to meet stringent environmental and health and safety targets. Finally, there is steady monitoring to make sure a dependable sealless pump efficiency which includes leak detection instrumentation and protection against dry pump working (power management monitor).
With no seals to leak, no seal buffer techniques to assist and maintain and no supporting systems, the most recent magnetic drive sealless pump expertise provides important safety, cost and operational advantages. Lower end-user installation prices and simplified maintenance requirements, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
