Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to process operators, including the risks related to the dealing with of a deadly, extremely corrosive fluid which poses a possible hazard to plant tools, the individuals who work on web site and the broader environment should leaks happen.
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 provide alkylate. A high-octane additive, alkylate is a important security part that offsets the high vapour stress of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of clean fuels’ laws has increased the demand for alkylate, which is also responsible for the anti-knocking property of unleaded petrol/gasoline in fashionable automobiles.
Potential risks
The HF alkylation course of poses numerous serious environmental and well being and security risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and associated HF release. เกจวัดแรงดันออกซิเจน by its nature seeks out and assaults imperfections in forged metallic elements that may ultimately scale back the lifetime of pumps, valves and different gear and worse still, lead to product leakage. Failure-prone mechanical seals can leak dangerous course of fluids. The aggressive and damaging nature of HF acid locations great importance on the selection of fabric of forged parts, significantly by method of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically designed for use in hydrofluoric acid alkylation items 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 main licensor of HF alkylation expertise and HMD Kontro, and utilizing an revolutionary improvement process, 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 features
Built into the design of those subsequent generation pumps are options which meet operator-specific needs for the HF alkylation course of. They embrace a pump casing in Alloy C22 materials, which has been proven to offer 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 40 bar (580 psi), eliminating the potential for leakage into the environment, and reducing operational dangers and the associated costs to meet stringent environmental and health and security goals. Finally, there’s continuous monitoring to make sure a dependable sealless pump performance which includes leak detection instrumentation and safety against dry pump operating (power management monitor).
With no seals to leak, no seal buffer methods to help and preserve and no supporting systems, the newest magnetic drive sealless pump know-how provides important security, value and operational advantages. Lower end-user set up prices and simplified maintenance necessities, make it an efficient whole-life proposition compared to standard mechanically sealed pumps.
