Title (EN) PROCESS FOR SEPARATING METHACROLEIN FROM METHACRYLIC ACID IN A GAS PHASE PRODUCT FROM THE PARTIAL OXIDATION OF ISOBUTENE
(FR) PROCÉDÉ POUR SÉPARER LA MÉTHACROLÉINE DE L'ACIDE MÉTHACRYLIQUE DANS UN PRODUIT EN PHASE GAZEUSE ISSU DE L'OXYDATION PARTIELLE D'ISOBUTÈNE
Abstract: front page image
(EN)A system and process for separating methacrolein (MA) from methacrylic acid (MAA) and acetic acid in the gas phase product from partial oxidation of isobutylene (IB) in two oxidation steps is disclosed. The process and system maximize recovery of all three components at minimum capital and energy cost, under conditions that minimize polymerization conditions and plugging by solids deposition in compressors, columns, etc.
(FR)L'invention concerne un système et un procédé pour séparer la méthacroléine (MA) de l'acide méthacrylique (MAA) et de l'acide acétique dans le produit en phase gazeuse issu de l'oxydation partielle d'isobutylène (IB) en deux étapes d'oxydation. Le procédé et le système selon l'invention permettent d'optimiser la récupération de ces trois composants à un coût financier et énergétique minimum, dans des conditions réduisant au minimum les conditions de polymérisation et le colmatage par dépôt de matières solides dans des compresseurs, des colonnes, etc.
