ตัววัดแรงดัน that includes new technologies, specifically designed for use in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing utility which poses explicit challenges to course of operators, together with the dangers related to the handling of a lethal, extremely corrosive fluid which poses a possible hazard to plant gear, the individuals who work on site and the broader environment should leaks occur.
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a important safety element that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continual tightening of clean fuels’ legislation has elevated the demand for alkylate, which is also liable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
The HF alkylation process poses a quantity of serious environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated equipment corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in forged steel parts that may finally cut back the life of pumps, valves and different tools and worse still, end in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places great importance on the selection of fabric of solid elements, notably by method of the pump casing and impeller.
Designed for resistance against highly corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed for use 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 leading licensor of HF alkylation technology and HMD Kontro, and utilizing an progressive development process, the HMD Kontro HF pump features a excessive integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next era pumps are features which meet operator-specific needs for the HF alkylation process. They embody a pump casing in Alloy C22 supplies, which has been proven to supply the required 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 chance of leakage into the environment, and reducing operational risks and the associated prices to meet stringent environmental and health and security goals. Finally, there could be steady monitoring to make sure a dependable sealless pump efficiency which incorporates leak detection instrumentation and safety in opposition to dry pump working (power control monitor).
With no seals to leak, no seal buffer techniques to assist and preserve and no supporting methods, the newest magnetic drive sealless pump technology presents important security, cost and operational benefits. Lower end-user installation costs and simplified upkeep requirements, make it an effective whole-life proposition in comparison with typical mechanically sealed pumps.
