Sealless pump design tackles HF alkylation

pressure gauge nuova fima ราคา that includes new technologies, 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 explicit challenges to course of operators, together with the dangers associated with the dealing with of a deadly, extremely corrosive fluid which poses a potential hazard to plant gear, the people who work on website and the broader surroundings should leaks occur.
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 produce alkylate. A high-octane additive, alkylate is a crucial security element that offsets the high vapour pressure of the ethanol mandated in today’s low-sulphur unleaded petrol and gasoline provides. The continuous tightening of fresh fuels’ laws has elevated the demand for alkylate, which can also be liable for the anti-knocking property of unleaded petrol/gasoline in fashionable vehicles.
Potential risks
The HF alkylation course of poses numerous severe environmental and health 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 attacks imperfections in cast metallic parts that can in the end reduce the life of pumps, valves and other tools and worse nonetheless, end in product leakage. Failure-prone mechanical seals can leak harmful process fluids. The aggressive and damaging nature of HF acid locations nice significance on the selection of material of cast elements, significantly in phrases of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids similar to HF acids, magnetic drive sealless pumps supply total containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been particularly designed to be used in hydrofluoric acid alkylation items and have been developed in response to the challenges of handling HF acid.

HMD Kontro HF pump
The results of shut collaboration between UOP Honeywell, the leading licensor of HF alkylation expertise and HMD Kontro, and utilizing an revolutionary improvement course of, the HMD Kontro HF pump contains a high 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 these next technology pumps are options which meet operator-specific wants for the HF alkylation process. They include a pump casing in Alloy C22 materials, which has been confirmed to offer the mandatory resistance to corrosion and in addition meets NDE necessities for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the potential for leakage into the environment, and decreasing operational risks and the related costs to fulfill stringent environmental and health and security targets. Finally, there could be steady monitoring to ensure a reliable sealless pump efficiency which incorporates leak detection instrumentation and protection in opposition to dry pump operating (power control monitor).
With no seals to leak, no seal buffer systems to support and keep and no supporting techniques, the newest magnetic drive sealless pump know-how offers significant safety, price and operational benefits. Lower end-user set up costs and simplified upkeep necessities, make it an efficient whole-life proposition in comparison with typical mechanically sealed pumps.
