Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to process operators, including the risks associated with the handling of a deadly, highly corrosive fluid which poses a possible hazard to plant gear, the people who work on web site and the broader setting should leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to produce alkylate. A high-octane additive, alkylate is a crucial safety part that offsets the excessive vapour strain of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of fresh fuels’ legislation has elevated the demand for alkylate, which can be answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential dangers
The HF alkylation process poses numerous serious environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in forged metal components that may finally scale back the life of pumps, valves and different gear and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid places great significance on the selection of fabric of solid components, particularly when it comes to the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly designed for use in hydrofluoric acid alkylation units and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and using an innovative development course of, 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 options
Built into the design of those subsequent era pumps are options which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory 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 potential for leakage into the environment, and lowering operational risks and the associated prices to satisfy stringent environmental and health and safety objectives. Finally, there’s steady monitoring to ensure a dependable sealless pump efficiency which includes leak detection instrumentation and protection towards dry pump running (power control monitor).
With no seals to leak, no seal buffer methods to support and preserve and no supporting methods, the newest magnetic drive sealless pump expertise offers important security, value and operational benefits. pressure gauge น้ำ -user set up costs and simplified maintenance requirements, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
