Sealless pump design tackles HF alkylation

Magnetic drive sealless pumps that includes new applied sciences, specifically designed for use in Hydrofluoric Acid (HF) Alkylation, have been developed in response to the challenges of handling HF acid.

Hydrofluoric acid alkylation is a chemical/hydrocarbon processing software which poses specific challenges to course of operators, including the dangers associated with the handling of a lethal, highly corrosive fluid which poses a potential hazard to plant tools, the individuals who work on site and the wider setting should leaks occur.
The process
HF Alkylation combines olefins (primarily a mixture of propylene and butylene) with isobutene within the presence of a hydrofluoric acid catalyst to provide alkylate. ร้านซ่อมเครื่องวัดความดัน -octane additive, alkylate is a important security component 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 elevated the demand for alkylate, which is also answerable for the anti-knocking property of unleaded petrol/gasoline in trendy automobiles.
Potential risks
The HF alkylation course of poses a selection of severe environmental and well being and security dangers if poorly managed, with the potential for acid runaway, accelerated tools corrosion and related HF launch. HF acid by its nature seeks out and assaults imperfections in solid steel components 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 process fluids. The aggressive and damaging nature of HF acid locations nice importance on the choice of fabric of forged components, notably by means of the pump casing and impeller.
Designed for resistance in opposition to extremely corrosive fluids corresponding to HF acids, magnetic drive sealless pumps provide complete containment with built-in reliability. Magnetic drive sealless pumps that includes new technologies have been specifically 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 results of shut collaboration between UOP Honeywell, the main licensor of HF alkylation expertise and HMD Kontro, and using an progressive 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 using new strategies of Non-Destructive Examination (NDE).
Specialist design options
Built into the design of those next era pumps are features which meet operator-specific needs for the HF alkylation process. They embrace a pump casing in Alloy C22 materials, which has been proven to supply the mandatory resistance to corrosion and also meets NDE requirements for HF acid. In addition, the pump’s secondary containment system is rated to forty bar (580 psi), eliminating the chance of leakage into the environment, and lowering operational dangers and the associated prices to meet stringent environmental and well being and security targets. Finally, there is continuous monitoring to ensure a reliable sealless pump performance which incorporates leak detection instrumentation and safety towards dry pump running (power management monitor).
With compound gauge ราคา to leak, no seal buffer methods to support and keep and no supporting systems, the most recent magnetic drive sealless pump expertise offers important safety, cost and operational benefits. Lower end-user installation prices and simplified upkeep requirements, make it an effective whole-life proposition in comparability with typical mechanically sealed pumps.
