Abstract

"MéTODO PARA INIBIR A OBSTRUçãO DE UM CONDUTO". Um método para inibir a obstrução de um conduto contendo uma mistura escoável, compreendendo pelo menos uma quantidade de hidrocarbonetos capazes de formar hidratos na presença de água e uma quantidade de água, método este compreendendo adicionar à mistura uma quantidade de um composto dendrimérico eficaz para inibir a formação de hidratos em temperaturas e pressões de condutos e o escoamento da mistura contendo o composto dendrimérico e quaisquer hidratos através do conduto. Preferivelmente, uma poliéster amida hiper-ramificada é usada como composto inibidor de formação de hidrato.
