Title (EN) PROCESSES FOR PRODUCING ACRYLIC ACIDS AND ACRYLATES
(FR) PROCÉDÉS DE PRODUCTION D'ACIDES ACRYLIQUES ET D'ACRYLATES
Abstract: front page image
(EN)In one embodiment, the invention is to a process for producing an acrylate product. The process comprises the step of providing a crude product stream comprising the acrylate product and an alkylenating agent. The process further comprises the step of separating at least a portion of the crude product stream to form an alkylenating agent stream and an intermediate product stream. The alkylenating agent stream comprises at least 1 wt% alkylenating agent and the intermediate product stream comprises acrylate product. The separating is performed in at least one column at an operating pressure ranging from 40 kPa to 80 kPa.
(FR)L'invention concerne, dans un mode de réalisation, un procédé de production d'un produit d'acrylate. Le procédé consiste à utiliser un flux d'un produit brut comprenant le produit d'acrylate et un agent d'alkylénation. Le procédé consiste en outre à séparer au moins une partie du flux du produit brut pour former un flux d'agent d'alkylénation et un flux de produit intermédiaire. Le flux d'agent d'alkylénation comprend au moins 1% en poids de l'agent d'alkylénation et le flux de produit intermédiaire comprend le produit acrylate. La séparation s'effectue dans au moins une colonne, à une pression effective de 40 kPa à 80 kPa.
