Dal 23 al 27 giugno 2019 a Roma, Sea Marconi parteciperà come speaker e silver sponsor alla conferenza internazionale ICDL (IEEE International Conference on Dielectric Liquids). L’ICDL, alla sua ventesima edizione, ospita i maggiori esperti di settore ed è senza dubbio l’evento dell’anno per tutti i professionisti impegnati a vario titolo nella gestione del ciclo di vita (LCM) di apparecchiature elettriche e fluidi isolanti.
L’intervento di Sea Marconi avrà come titolo “Corrosions & PCBs: Inventory, Diagnostics and Treatments of Oils and Transformers”, (vd. abstract sotto)* ed offre un approccio di Risk Management and Asset Management su apparecchiature con fluidi isolanti come i trasformatori. In particolare il paper descrive tecnicamente la soluzione a due importanti criticità (“patologie”): le corrosioni e la contaminazione da PCB. Sea Marconi è in grado di fornire una risposta completa offrendo un servizio di assoluta eccellenza nell’analisi del fluido (grazie al laboratorio accreditato Accredia), nella diagnosi e prognosi delle criticità e nel trattamento di queste ultime.
All’ICDL Sea Marconi presenterà anche un poster (apri il file) dal titolo: “Life Cycle Management of Natural Esters & Transformers according to IEC Standards: Case History of EnvirotempTM FR3TM Fluid & TransfoClean® Bio Solutions in Brasil.” Questo studio, condotto in collaborazione con Cargill, l’Università la Sapienza di Roma e l’Università del Missouri (Rolla – USA) esprime l’impegno e la direzione di Sea Marconi nell’essere pioniera anche nell’ambito degli esteri naturali, un prodotto che rispecchia la naturale propensione dell’azienda nel cercare soluzioni ambientalmente sostenibili.
*Abstract
This paper describes the “State of the Art” for inventory, diagnostic, prognostic and integrated treatment of electrical equipment and insulating liquids containing DBDS/Corrosions & PCBs (Tech Pathologies). The Corrosions determine functional risks for transformers and equipment filled with mineral insulating oils: C1-DBDS &Corrosive Sulfur; C2-NOT DBDS &Corrosive Sulfur; C3-.SCBP & Corrosive Sulfur; C4-NOT Corrosive Sulfur &Metal Dissolution.
The PolyChlorinatedBiphenyls (PCBs) are a “Persistent Organic Pollutants” (POPS), as “Class 1.Cancerogenic to humans (IARC 2013) and determine risks for workers, public health and environment.
The oils & transformers integrated treatments, PCBs dehalogenation technique (“DMU & CDP Process” patented by Sea Marconi) and DBDS Selective Depolarization, in continuous mode through a closed circuit process are the sustainable solutions (Therapies) based on “circular economy”.
These solutions are based on the use of Smart Decontamination Modular Units (DMUs) and a solid reagent, consisting of a higher molecular weight glycol compounds, a mixture of bases and radical promoter or other catalyst on a high surface area particulate support. These processes normally run at 80-100 °C and have the capability to decontaminate equipment on-site through continuous circulation of the oil in a closed system (without draining the oil or using auxiliary tanks), using the solvent capability of the oil for continuous extraction of PCBs and DBDS from solid materials inside the equipment (according IEC 60422 art. 11.4.4).
International experience of diagnostic, prognostic and integrated treatments according to IEC & CENELEC include On-Load treatments in power transformers and shunt reactors, in several countries are presented.
Keywords — Transformer, Oil, Additives, PCBs, DBDS, Corrosive Sulfur, Total Corrosive Sulfur, Integrated Treatments, Selective Depolarization CDP Process, Dehalogenation.
