Abstract

La deposicion de asfaltenos y/o ceras de petroleo puede ser inhibida y/o los asfaltenos y/o las ceras de petroleo pueden ser eliminadas de un pozo, tubería o recipiente, poniendo en contacto el asfalteno y/o la cera de petroleo o el pozo, tubería o recipiente, en posicion adyacente a una ubicacion en donde cabe esperar la deposicion de asfalteno y/o cera de petroleo, con un disolvente que incluye al menos un compuesto de la formula: R1-(AO)N-OOC-(CH2)m-PH-(R2)p en donde: R1 es un grupo hidrocarbilo C1- 20; AO es un grupo alquilenoxi y puede variar a lo largo de la cadena (poli)alquilenoxi; n es 0 o es de 1 a 100; m es 0, 1 o 2; y Ph es un grupo fenilo que puede estar sustituido con grupo (R2)p en donde cada R2 es independientemente un grupo alquilo o alcoxi C1-4 y p es 0, 1 o 2; y separando posteriormente, del pozo, tubería o recipiente, el disolvente con los asfaltenos y/o cera de petroleo reblandecidos, disueltos o dispersados.The deposition of asphaltenes and / or oil waxes can be inhibited and / or asphaltenes and / or oil waxes can be removed from a well, pipe or container, bringing the asphaltene and / or the oil wax into contact. well, pipe or container, in a position adjacent to a location where the deposition of asphaltene and / or oil wax can be expected, with a solvent that includes at least one compound of the formula: R1- (AO) N-OOC- ( CH2) m-PH- (R2) p wherein: R1 is a C1-20 hydrocarbyl group; AO is an alkyleneoxy group and may vary along the (poly) alkyleneoxy chain; n is 0 or is 1 to 100; m is 0, 1 or 2; and Ph is a phenyl group that can be substituted with group (R2) p wherein each R2 is independently a C1-4 alkyl or alkoxy group and p is 0, 1 or 2; and subsequently separating, from the well, pipe or container, the solvent with the asphaltenes and / or oil wax softened, dissolved or dispersed.
