Abstract

<B>MéTODO PARA PREVENçãO OU RETARDAMENTO DA FORMAçãO DE HIDRATOS DE GáS<D>. Uma composição para prevenir ou retardar a formação de hidratos de gás ou para reduzir a tendência de hidratos de gás se aglomerarem, durante o transporte de um fluido compreendendo água e um hidrocarboneto, através de um conduto, compreendendo, a) um polímero ou copolímero selecionado de um terpolímero de pirrolidona de vinila, caprolactama de vinila e um monómero derivado de amónio tendo de 6 a 12 átomos de carbono, selecionados do grupo que consiste em metacrilamida dialquil aminoalquila, haleto de amónio de dialquil dialquenila e um acrilato ou matecrilato de dialquilamino alquila, um copolímero de pirrolidona de vinila e caprolactama de vinila, e um homopolímero de caprolactama de vinila, e b) um álcool contendo três a cinco átomos de carbono e um grupo hidróxi, ou um éter de glicol com baixo peso molecular contendo um grupo de alcoxi tendo pelo menos 3 átomos de carbono.
