Abstract

MÉTODO PARA INIBIR O ENTUPIMENTO DE UM CONDUTO. Um método para inibir o entupimento de um conduto que contém uma mistura escoável que compreende pelo menos uma quantidade de hidrocarbonetos capazes de formar hidratos na presença de água e uma quantidade de água, cujo método compreende adicionar à mistura uma quantidade de um dendrímero funcionalizado eficaz para inibir a formação e/ou o acúmulo de hidratos na mistura nas temperaturas e pressões do conduto; e escoar a mistura que contém o dendrímero funcionalizado e quaisquer hidratos através do conduto em que o dendrímero funcionalizado compreende pelo menos um grupo terminal polialquilenoglicol.
