Title (EN) PROCESS TO PRODUCE AND PURIFY MONOETHYLENE GLYCOL
(FR) PROCÉDÉ POUR PRODUIRE ET PURIFIER DU MONOÉTHYLÈNE GLYCOL
Abstract:
(EN) A process for producing purified monoethylene glycol (MEG) is provided. The process comprises contacting a mixture comprising MEG and primary co-products with an acid to provide a distillable MEG product, wherein the primary co-products have boiling points substantially similar to a boiling point of MEG, and wherein the distillable MEG product comprises MEG and secondary co-products that do not boil closely with MEG; and distilling the distillable MEG product to provide purified MEG and secondary co-products. A process for increasing production of MEG is also provided, comprising contacting a bio- derived MEG mixture comprising MEG and 1,2-butanediol (1,2-BDO) with an acid to provide a second MEG product, wherein the 1,2-BDO is converted to MEG.
(FR) L'invention concerne un procédé permettant de produire du monoéthylène glycol (MEG) purifié. Le procédé consiste : à mettre en contact un mélange comprenant du MEG et des coproduits primaires avec un acide pour obtenir un produit de MEG distillable, les coproduits primaires ayant des points d'ébullition sensiblement similaires au point d'ébullition du MEG, et le produit de MEG distillable comprenant du MEG et des coproduits secondaires dont le point d'ébullition n'est pas proche de celui du MEG ; et à distiller le produit de MEG distillable pour obtenir du MEG purifié et des coproduits secondaires. L'invention concerne également un procédé permettant d'accroître la production de MEG, consistant à mettre en contact un mélange de MEG d'origine biologique comprenant du MEG et du butane-1,2-diol (1,2-BDO) avec un acide pour obtenir un second produit de MEG, le 1,2-BDO étant converti en MEG.
