Abstract

USO DE POLIETILENOIMINAS SUBSTITUÍDAS COMO INIBIDORES DE HIDRATOS DE GÁS COM BIODEGRADABILIDADE MELHORADA. A presente invenção refere-se ao uso de polietilenoiminas substituidas contendo as unidades estruturais de fórmula (1), onde R1 é H, C~ 1~-C~ 30~-alquila, C~ 1~-C~ 30~-alquenila ou C~ 7~-C~ 30~-alquilariía R2, R3, R4, R5 são cada um, independentemente, H ou C~ 1~-C~ 6~-alquiía, em quantidades de cerca de 0,01 a 2% em peso para prevenir a formação de hidratos de gás em fases aquosas que estão em contato com uma fase orgânica gasosa, líquida ou sólida.
