Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses specific challenges to process operators, together with the dangers related to the handling of a lethal, extremely corrosive fluid which poses a possible hazard to plant tools, the people who work on web site and the wider environment should leaks occur.
The course of
HF Alkylation combines olefins (primarily a combination of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. A high-octane additive, alkylate is a crucial safety element that offsets the excessive vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous 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 fashionable vehicles.
pressure gauge ราคา ถูก poses a quantity of critical environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF launch. HF acid by its nature seeks out and attacks imperfections in cast steel parts that will ultimately scale back the lifetime of pumps, valves and other tools and worse nonetheless, result in product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid places nice significance on the choice of material of solid components, particularly by way of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps supply whole containment with built-in reliability. Magnetic drive sealless pumps featuring new applied sciences have been specifically designed to be used in hydrofluoric acid alkylation models 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 improvement process, the HMD Kontro HF pump includes a high integrity pump casing manufactured from Alloy C22 (ASTM A194 Gr. CX2MW) which has been tested utilizing new strategies of Non-Destructive Examination (NDE).
Specialist design features
Built into the design of those next generation pumps are options which meet operator-specific wants for the HF alkylation course of. They include a pump casing in Alloy C22 supplies, which has been confirmed to offer the required 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 reducing operational dangers and the associated costs to fulfill stringent environmental and well being and safety goals. Finally, there is steady monitoring to ensure a dependable sealless pump performance which incorporates leak detection instrumentation and safety towards dry pump working (power control monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting methods, the most recent magnetic drive sealless pump expertise presents significant security, price and operational benefits. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition compared to typical mechanically sealed pumps.
