Abstract
método para inibir o bloqueio de hidratos de gás em oleodutos e gasodutos. a presente invenção refere-se a um método para inibir a aglomeração de hidratos de gás, compreendendo a injeção de um antiaglomerante compreendendo uma amida de ácido graxo n,n dialquil-amonioalquila representada pela fórmula (i), em que r1 é um grupo alquila ou alquenila possuindo de 7 a 21 átomos de carbono, r2 a r3 são cada um independentemente um grupo alquila contendo 1 a 10 átomos de carbono, ou juntos formam um anel opcionalmente substituído com 5 a 10 átomos de anel, em que o anel pode conter até 3 substitutos, r4 é hidrogênio ou um grupo alquila possuindo 1 a 6 átomos de carbono, r5 é hidrogênio ou um grupo hidrocarbila opcionalmente substituída possuindo 1 a 22 átomos de carbono, e a é um grupo de alquileno pos-suindo dois ou três átomos de carbono, em um fluido compreendendo gás, água e óleo sob condições propícias à formação de hidratos de gás, em que a amida de ácido graxo n,n dialquil-amonioalquila representada pela fórmula (i) é produzido pela aminólise de um éster de um ácido graxo e de um álcool c1 - a c4 com uma n,n-dialquilamino alquil amina, e subsequente neutralização com um ácido carboxílico.
