xp2i that includes new applied sciences, specifically designed to be used in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of dealing with HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing application which poses particular challenges to course of operators, together with the risks associated with the dealing with of a lethal, highly corrosive fluid which poses a potential hazard to plant equipment, the individuals who work on web site and the broader setting ought to leaks occur.
The process
HF Alkylation combines olefins (primarily a mix of propylene and butylene) with isobutene in the presence of a hydrofluoric acid catalyst to produce alkylate. เกจวัดแรงดัน4นิ้วราคา -octane additive, alkylate is a crucial safety part that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of unpolluted fuels’ laws has increased the demand for alkylate, which can additionally be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable autos.
Potential dangers
The HF alkylation process poses numerous severe environmental and health and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and associated HF release. HF acid by its nature seeks out and assaults imperfections in forged metallic parts that may ultimately cut back the life of pumps, valves and other tools and worse nonetheless, lead to product leakage. Failure-prone mechanical seals can leak dangerous process fluids. The aggressive and damaging nature of HF acid locations great significance on the selection of fabric of solid elements, notably when it comes to the pump casing and impeller.
Designed for resistance towards extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide whole containment with built-in reliability. Magnetic drive sealless pumps that includes new applied sciences have been particularly designed for use in hydrofluoric acid alkylation items and have 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 know-how and HMD Kontro, and using an innovative improvement course of, 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 options
Built into the design of these next era 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 proven to offer the necessary 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 of leakage into the environment, and decreasing operational risks and the associated prices to meet stringent environmental and health and safety targets. Finally, there is continuous monitoring to make sure a dependable sealless pump performance which incorporates leak detection instrumentation and safety against dry pump running (power management monitor).
With no seals to leak, no seal buffer systems to help and maintain and no supporting methods, the most recent magnetic drive sealless pump know-how provides important security, price and operational benefits. Lower end-user set up prices and simplified maintenance necessities, make it an effective whole-life proposition in comparability with conventional mechanically sealed pumps.
