Abstract

Se proporciona un proceso continuo para convertir residuos plásticos en reciclaje para la polimerización de polietileno. En una modalidad, el proceso comprende la selección de residuos plásticos que contienen polietileno y/o polipropileno y pasan los residuos plásticos a través de un reactor de pirólisis para craquear térmicamente al menos una porción de los residuos de poliolefina y producir un efluente pirolizado. El efluente pirolizado se separa en gas residual, una fracción nafta/diésel, una fracción pesada y carbón. La fracción de nafta/diésel se pasa a una columna de destilación de la unidad crudo en una refinería en donde se recupera una fracción de nafta de destilación directa (C5-C8) o una fracción de propano/butano (C3-C4). La fracción de nafta de destilación directa (C5-C8) o la fracción de propano/butano (C3-C4) se pasa a un craqueador de vapor para la producción de etileno. La fracción pesada de la unidad de pirólisis también se puede pasar a una unidad de desparafinado por isomerización para producir un aceite base.
