VERFAHREN ZUR GEWINNUNG VON ETHYLEN AUS METHAN

摘要

A process for the recovery of ethylene from methane in which one or more methane-containing feed gas mixtures preheated and one or more reactors (1) are fed, in the which a portion of the methane in the contained or the use of gas mixtures is converted by oxidative coupling to ethylene or, wherein the preheating of or the use of mixtures using one or more heat exchangers (2) is performed in which or to which one or more product mixtures, the or removed the the one or more reactors (1) are cooled, and wherein the preheating of the or the use of mixtures during a start-up period, in addition, using a fuel-fired gas heater (3) is carried out, characterized in that the or the feed gas mixtures out at least during the start-up in parallel flow guide through the or the heat exchanger (2) and by the gas heater (3) become. A corresponding system (100) is also a subject of the invention.
