Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses explicit challenges to course of operators, together with the dangers related to the dealing with of a deadly, highly corrosive fluid which poses a possible hazard to plant gear, the individuals who work on website and the broader environment should leaks occur.
The course of

HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to supply alkylate. A high-octane additive, alkylate is a important security component that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continual tightening of clean fuels’ laws has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in modern vehicles.
Potential risks

The HF alkylation course of poses a variety of severe environmental and health and safety dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and related HF release. pressure gauge by its nature seeks out and assaults imperfections in cast metal parts that may ultimately reduce the lifetime of pumps, valves and other tools and worse still, 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 choice of fabric of forged components, notably when it comes to the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed for use in hydrofluoric acid alkylation units and have 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 leading licensor of HF alkylation expertise and HMD Kontro, and using an progressive growth 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 using new methods of Non-Destructive Examination (NDE).
Specialist design features

Built into the design of these next generation pumps are features which meet operator-specific needs for the HF alkylation course of. เกจวัดแรงดัน embody a pump casing in Alloy C22 supplies, which has been proven to supply the mandatory resistance to corrosion and in addition meets NDE requirements 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 surroundings, and decreasing operational dangers and the related prices to fulfill stringent environmental and well being and security goals. Finally, there may be continuous monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and safety in opposition to dry pump running (power management monitor).
With no seals to leak, no seal buffer methods to assist and maintain and no supporting systems, the most recent magnetic drive sealless pump technology offers significant safety, price and operational advantages. Lower end-user installation prices and simplified maintenance necessities, make it an effective whole-life proposition compared to conventional mechanically sealed pumps.
