Synthesis of New Polymeric Nanolattices Via Emulsion Polymerization And Their Applications In Petroleum Industries

Abstract

Corrosion management is a key concern in all oil and gas assets due to the nature of fluids produced and injected throughout their life cycle. This is applicable for all asset types, regardless of their age and the level of corrosive agents’ present in the flow stream, such as CO2, H2S, water or chlorides. Accordingly, application of effective corrosion management concerning different types of mitigations like application of coating, chemical treatment and material selection are important elements. The main object of this work is to synthesize a highly water-repellent film (superhydrophobic coated film) to be used for corrosion protection of carbon steel pipelines. To achieve this purpose, polystyrene, styrene / vinyl acetate copolymer using emulsion polymerization technique, SiO2 nanoparticles and nanocomposites were prepared and evaluated as corrosion inhibitors of carbon steel.

The prepared polymers and their composites were characterized using a variety of techniques, namely: (i) FT-IR, (ii) 1H-NMR spectroscopy, (iii) Gel permeation chromatography (GPC) (for molecular weight determination), (iv) Thermogravimetric analysis (TGA), (v) differential scanning calorimetry (DSC), (vi) dynamic light scattering (DLS), (vii) transmission electron microscopy (TEM), (viii) energy dispersive X-ray spectroscopy (EDX), (ix) X-ray diffraction (XRD), (x) scanning electron microscopy (SEM), (xi) contact angle measurements, (xii) atomic force microscopy (AFM). The prepared polymers and their composites were evaluated as superhydrophobic coating films to be used as corrosion resistant materials for carbon steel.
