Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses particular challenges to course of operators, together with the risks related to the handling of a lethal, extremely corrosive fluid which poses a potential hazard to plant equipment, the people who work on web site and the broader setting should leaks occur.
เกจวัดแรงดันลมราคา 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 crucial security element that offsets the excessive vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline supplies. The continuous tightening of fresh 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 dangers
The HF alkylation process poses a number of serious environmental and well being and safety risks if poorly managed, with the potential for acid runaway, accelerated gear corrosion and related HF release. HF acid by its nature seeks out and assaults imperfections in forged metal parts that will in the end scale back the life of pumps, valves and different gear and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid places great significance on the selection of fabric of solid components, notably by way of the pump casing and impeller.
Designed for resistance against extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps offer complete containment with built-in reliability. Magnetic drive sealless pumps featuring new technologies have been particularly 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 result of close collaboration between UOP Honeywell, the main licensor of HF alkylation technology and HMD Kontro, and using an progressive development 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 utilizing new methods of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those subsequent 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 confirmed to supply the required resistance to corrosion and also meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to 40 bar (580 psi), eliminating the possibility of leakage into the environment, and lowering operational dangers and the associated costs to fulfill stringent environmental and health and safety objectives. Finally, there is เกจวัดอาร์กอน monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and protection towards dry pump working (power control monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting techniques, the latest magnetic drive sealless pump technology presents significant security, value and operational advantages. Lower end-user installation costs and simplified upkeep requirements, make it an efficient whole-life proposition in comparability with conventional mechanically sealed pumps.
