Title
(EN) METHANE ETHANE CRACKERS
(FR) CRAQUEURS D'ÉTHANE AU MÉTHANE
Abstract
(EN)
A process for producing olefins by cracking paraffins in the presence of methane. In the conventional steam cracking processes for olefin production, steam is used as a diluent in the feed mixture to the thermal cracker. In the processes provided herein, methane replaces steam as a diluent in the feed mixture to the thermal cracker. Replacing steam with methane as a diluent has a potential for cost savings in the construction and operation of a thermal cracking plant for olefin production. In addition, it leads to a much simpler cracking process compared to the conventional steam cracking technology as in the state of the art.

L'invention concerne un procédé de production d'oléfines par craquage de paraffines en présence de méthane. Dans les procédés classiques de vapocraquage pour la production d'oléfines, de la vapeur est utilisée en tant que diluant dans le mélange d'alimentation du craqueur thermique. Dans les procédés décrits ici, le méthane remplace la vapeur en tant que diluant dans le mélange d'alimentation du craqueur thermique. Le remplacement de la vapeur par du méthane en tant que diluant présente un potentiel d'économies de coût de construction et de fonctionnement d'une installation de craquage thermique pour la production d'oléfines. De plus, il permet un procédé de craquage beaucoup plus simple par rapport à la technologie classique de vapocraquage comme dans l'état de la technique.
