A method for producing green olefins and green gasoline from renewable sources, the method including: providing COand hydrogen as feed to produce methanol in a methanol reactor, to produce an MTO reaction effluent, reacting the MTO reaction effluent in a plurality of separation columns to separate hydrocarbons, wherein the plurality of separation columns includes a Deethanizer column, a Depropanizer column, and a Debutanizer column, hydrogenating a fraction of separated hydrocarbons in the Debutanizer column with the hydrogen in a hydrogenation reactor, wherein the fraction of separated hydrocarbons from the Debutanizer column includes Chydrocarbons; producing the green gasoline and Liquefied Petroleum Gas (LPG) by stabilizing the hydrogenated hydrocarbons in a gasoline stabilizer column; and producing the olefins by separating ethylene from Chydrocarbons using a Csplitter column and by separating propylene from Chydrocarbons using a Csplitter column.

Method and apparatus for producing green olefins and green gasoline from renewable sources

The present invention relates to a plant and a process for producing propylene at least one oxygenate, comprising a reactor for converting the reactant mixture into a product mixture which comprises propylene and also aliphatic and aromatic Chydrocarbons, at least one distillation column for removing a Cstream, the Cstream comprising at least 90 wt % of the aliphatic and aromatic Chydrocarbons of the product mixture, an extractive distillation column for separating the Cstream into an aromatics stream and an aliphatics stream, the aliphatics stream comprising at least 90 wt % of the aliphatics of the Cstream, and the aromatics stream comprising at least 90 wt % of the aromatics of the Cstream, and an aliphatics recycle line for at least partial recycling of the aliphatics stream to the reactor. According to the invention, an aromatics recycle line is provided which returns the aromatics stream at least partially as extractant into the extractive distillation column.
