Bio-nanocoatings based on castor oil enhanced with nanomaterials as corrosion reducers in injection wells pipelines.

Corrosion is a recurring problem in the oil and gas industries. The application of coatings has been demonstrated to prevent the corrosion of pipelines and associated infrastructure, reducing maintenance and repair costs. In this study, an alkyd-urethane coating based on castor oil with the addition of alumina (AlO), carbon quantum dots (CQDs), and silica (SiO) nanoparticles as corrosion reducers in injection-well pipelines is evaluated.

Effect of the chemical nature of the nitrogen source on the physicochemical and optoelectronic properties of carbon quantum dots (CQDs).

This study investigates the influence of the chemical nature of nitrogen sources on the optical properties of Carbon Quantum Dots (CQDs) and evaluates their suitability for various industrial applications through a series of stability tests. Four nitrogen sources, -diethanolamine, diethylamine, ethylenediamine, and 1,2-phenylenediamine- were used to synthesize surface-active CQDs a one-step microwave-assisted carbonization method. All CQDs exhibited a negative surface charge, ranging from -24.

Improvement in Heat Transfer in Hydrocarbon and Geothermal Energy Coproduction Systems Using Carbon Quantum Dots: An Experimental and Modeling Approach.

The main objective of this study is to improve heat transfer in hydrocarbon- and geothermal-energy coproduction systems using carbon quantum dots (CQDs). Two types of 0D nanoparticles (synthesized and commercial CQDs) were used for the formulation of nanofluids to increase the heat transfer from depleted wells for the coproduction of oil and electrical energy. The synthesized and commercial CQDs were characterized in terms of their morphology, zeta potential, density, size, and heat capacity.

Effect of Textural Properties and Surface Chemical Nature of Silica Nanoparticles from Different Silicon Sources on the Viscosity Reduction of Heavy Crude Oil.

The main objective of this study is to evaluate the effect of the textural properties and surface chemical nature of silica nanoparticles obtained from different synthesis routes and silicon precursors, on their interactions with asphaltenes and further viscosity reduction of heavy crude oil (HO). Four different SiO nanoparticles were used, namely, commercial fumed silica nanoparticles (CSNs) and three in-house-synthesized nanoparticles (named based on the silicon source) modifying the silicon precursor: sodium silicate (SNSS), tetraethylorthosilicate (TEOS) (SNT), and rice husk (SNRH). The nanomaterials were characterized through dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, N physisorption ( ), atomic force microscopy (AFM), and X-ray photoelectron (XP) spectroscopy (XPS).
