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 memos etileno, etano y metano y compuestos con puntos de ebullición más 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 que, después de la adsorción por intercambio de presión (4), la mezcla de productos se someta a uno o más pasos de acondicionamiento y que, luego de ello, se procese utilizando tecnología de separación para obtener un producto rico en etileno.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 ethylene, ethane and methane and compounds with boiling points lower than methane and higher than ethane. It is envisaged that, from the mixture of products, by means of an adsorption method (4), initially between 60 and 90 mole percent of methane and at least a part of the components with lower boiling points will be removed than methane. and that, after adsorption by pressure exchange (4), the product mixture is subjected to one or more conditioning steps and, after that, is processed using separation technology to obtain a product rich in ethylene.
