Abstract

Se propone un proceso (100) para producir etileno a partir de metano, en el cual, con el uso de un método para el acoplamiento oxidativo de metano (1). Se prepara una mezcla de productos, la cual contiene al menos etileno, etano y metano y compuestos con puntos de ebullición mas bajos que el del metano y más altos que el del etano. Se prevé que, a partir de la mezcla de productos, por medio de un método de adsorción (4). inicialmente se elimine entre 60 y 90 por ciento en moles del metano y al menos una parte de los componentes con puntos de ebullición más bajos que el del metano, y entonces se someta la mezcla de productos a uno o más pasos de acondicionamiento, y que luego se procese mediante tecnología de separación para obtener un producto rico en etileno, procesamiento mediante tecnología de separación el cual consiste en una desmetanación (9), a la cual se somete al menos una parte de la mezcla de productos como materia prima de separación, y en la cual, una parte del metano y la parte predominante del etano y del etileno y de los compuestos con puntos de ebullición más altos que el del etano, inicialmente, se eliminan de la materia prima de separación por medio de un líquido de absorción.A process (100) is proposed to produce ethylene from methane, in which, with the use of a method for the oxidative coupling of methane (1). A mixture of products is prepared, which contains at least ethylene, ethane and methane and compounds with boiling points lower than methane and higher than ethane. It is expected that, from the mixture of products, by means of an adsorption method (4). Initially, 60 to 90 mole percent of methane and at least part of the components with lower boiling points than methane are removed, and then the product mixture is subjected to one or more conditioning steps, and that then it is processed by separation technology to obtain a product rich in ethylene, processing by separation technology which consists of a demetanation (9), to which at least a part of the product mixture is subjected as separation raw material, and in which, a part of methane and the predominant part of ethane and ethylene and of compounds with boiling points higher than that of ethane, initially, are removed from the separation raw material by means of an absorption liquid .
