Title (EN) SEPARATION OF OFF GASES FROM C3 HYDROCARBONS IN PROPANE DEHYDROGENATION PROCESS
(FR) SÉPARATION DE GAZ D’ÉCHAPPEMENT D’HYDROCARBURES C3 DANS UN PROCÉDÉ DE DÉSHYDROGÉNATION DE PROPANE
Abstract: front page image
(EN) Methods and systems for separating C3 hydrocarbons from lighter hydrocarbons, carbon monoxide, carbon dioxide, and water are provided. In certain embodiments, the methods include feeding a gaseous mixture including C1, C2, and C3 hydrocarbons and benzene solvent to the absorber column where benzene solvent selectively absorbs C3 hydrocarbons. The methods can further include removing a first stream comprising benzene solvent and absorbed C3 hydrocarbons from the absorber column, and feeding the first stream to a stripper column where benzene solvent is separated from C3 hydrocarbons, and removing a second stream comprising C3 hydrocarbons from the stripper column.
(FR) L'invention concerne des procédés et des systèmes de séparation d'hydrocarbures C3 à partir d'hydrocarbures plus légers, de monoxyde de carbone, de dioxyde de carbone et d'eau. Selon certains modes de réalisation, les procédés comprennent l'introduction d'un mélange gazeux comprenant des hydrocarbures C1, C2 et C3 et un solvant de benzène dans la colonne d'absorption où le solvant de benzène absorbe sélectivement les hydrocarbures C3. Les procédés peuvent en outre comprendre le retrait d'un premier flux comprenant du solvant de benzène et des hydrocarbures C3 absorbés de la colonne d'absorption, et l’introduction du premier flux dans une colonne de rectification dans laquelle le solvant de benzène est séparé des hydrocarbures C3, et le retrait d’un deuxième flux comprenant des hydrocarbures C3 de la colonne de rectification.
