- REMOVAL OF HYDROCARBONS FROM DRILL CUTTINGS USING HUMIC ACIDS IN WASHING PROCESSES Marcos Leopoldo INTERIANO LÓPEZ Víctor Ángel RAMÍREZ COUTIÑO Evelyn ZAMUDIO PÉREZ Luis A. GODÍNEZ Francisco J. RODRÍGUEZ-VALADEZ Ciencias de la Tierra TPH surfactants humic acids washing process In petroleum exploration drilling cuttings are generated, which are toxic residues that contain significant amounts of oil. The oil levels within the cuttings are a risk for marine and terrestrial environments. This study was carried out to investigate the removal of total petroleum hydrocarbons (TPH) in perforation cuttings (OBDC) by a washing process in which humic acids (HA) were used as surfactants. The cuttings contained 114372 mg/kg of TPH, which were washed with HA solutions, resulting in 80 % removal of OBDC contaminants, applying a washing an additional water rinse. The process effectiveness was found strongly dependent on the HA solution concentration, the highest removal rates were attained using solutions in the range of 2500 to 3000 mg/L, and lower concentrations yielded removal rates lower than 70 %. Comparing the use of HA versus synthetic surfactants, such as sodium dodecyl sulfate (SDS) and tween-20 (TW20), both resulted in lower removal efficiency than HA. An additional advantage of HA is that it is a natural material, therefore there is no risk of toxic side effects that occur with synthetic surfactants. 2019 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37066256016 https://www.redalyc.org/journal/370/37066256016/ https://www.redalyc.org/journal/370/37066256016/html/ https://www.redalyc.org/journal/370/37066256016/37066256016.epub https://www.redalyc.org/journal/370/37066256016/movil en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.3 Vol.35
