RESUMEN Serealizounacaracterizacionfisicoquimicaamuestrasdetrietilenglicolrico(encontactocon gas natural y humedad), trietilenglicol pobre TEGP (sin humedad) y agua de condensacion tomadas del sistema de trietilenglicol ACT de una unidad criogenica. Se realizo pruebas de resistencia a la polarizacion lineal (LPR) y curvas de polarizacion Tafel para determinar la velocidaddecorrosiondelTEGR,TEGPYACTylaeficienciadelinhibidordecorrosion (Coastal 1755) en diferentes concentraciones para condiciones estaticas. Para la evaluacion se utilizo un electrodo de anillo rotatorio acoplado a un potenciostato galvanostato Autolab/ PGSTAT 302N, utilizando procedimientos de acuerdo con la norma ASTM G-170- 01, "StandardGuideforEvaluatingandQualifyingOilFieldandRefineryCorrosionInhibitors in the Laboratory". Se caracterizo el deposito de corrosion extraido del sistema de drenaje mediante espectrometria de emision Jarell Ash y difraccion de rayos X, marca Phillips. La velocidad de corrosion del agua de proceso sin inyeccion de inhibidor esta en el orden de 4 mpy (0,114 mm/ano) y para las mezclas de trietilenglicol se consideran despreciables, por lo tanto el inhibidor Coastal 1755-C esta neutralizando la acidez y controlando la corrosion en el sistema. Palabras clave: Neutralizador de glicol, inhibidor de corrosion, trietilenglicol, azufre. ABSTRACT A physicochemical characterization was conducted for samples of rich triethylenglycol RTEG (contacted with natural gas and moisture), poor glycol PTEG (without moisture) and water of condensation taken from a cryogenic unit TWC. Tests of linear polarization resistance (LPR) and Tafel polarization curves were performed to determine the corrosion rate of RTEG, PTEGandTWR(Tegwaterremoved)andthecorrosioninhibitor(Coastal1755)efficiency at different concentrations for static conditions. One rotating ring electrode coupled to a potentiostat galvanostat Autolab/PGSTAT 302N was used for evaluation, using procedures in accordance with ASTM G-170- 01, "Standard Guide for Evaluating and Qualifying Oil Field andRefineryCorrosionInhibitorsintheLaboratory". The corrosion deposit extracted from the drainage system was characterized by an emission spectrometer, brand Jarrel Ash and x-ray diffraction brand Phillips.
