    Near superhydrophobic carbon nanotube coatings obtained via electrophoretic deposition on low-alloy steels

    Sucker rods are a key element in certain oil-extraction processes as they link the motor group on the surface with the pumps located downhole. During the transport from the production site toward the extraction well, these components are prone to corrosion. A hydrophobic carbon nanotube (CNT) coating, deposited via electrophoretic deposition (EPD), is proposed as a protective layer, shielding the rods from harsh environmental conditions. Three different coating systems are considered and thoroughly characterized (depending on the additive that is used to deposit the CNT), namely, magnesium nitrate hexahydrate (Mg– Nit), triethylamine (TEA), and a duplex coating (DD). The latter presents an approach which combine s the advantages of each additive, mechanical stability from Mg–Nit and strong hydrophobicity from TEA (near superhydrophobic). The former coatings are further processed to overcome their individual shortcomings,resulting in an increase in the coating’s stability for TEA coating, as well astransforming the hydrophilic Mg–Nit surface into a hydrophobic surface.

    Planta de producción de biodiesel a partir de aceite vegetal usado
    (2020-04-16) Zivelonghi, Nazareno Nahuel; Martin, Matías Sebastián
    El presente trabajo, busca dar una alternativa ecológica y económicamente viable al consumo de combustible fósil, diseñando una planta de producción de biodiesel a partir de aceite vegetal usado. El biodiesel, se obtendrá a través del proceso de transesterificación del aceite, el cual consiste en hacerlo reaccionar, mezclándolo con un aditivo catalizador dentro de un reactorpresurizado y calefaccionado. Posteriormente, el biodiesel se estacionará, se lavará y se almacenará dentro de tanques para poder ser despachado. Así, con una inversión que se amortizará en un período de tiempo corto, se podrán obtener unos 400 litros por día de Biodiesel, ahorrando esa cantidad de gasoil fósil.
