Oxygenated hydrocarbon production system with acidic impurity removal resin column

An oxygenated hydrocarbon production system, comprising:

• a monoesterification reactor comprising a maleic anhydride inlet, a monoesterification alcohol inlet, and one or more monoester outlets, the monoesterification reactor being configured to receive a maleic anhydride stream and a monoesterification alcohol stream comprising an alcohol having 1 to 3 carbon atoms, convert the maleic anhydride and alcohol to a monoester, and provide a monoester stream comprising the monoester;
• one or more diesterification reactors, each comprising a monoester inlet fluidly connected to the monoester outlet of the monoesterification reactor, a diesterification alcohol inlet, a crude diester outlet, and a diesterification waste outlet, each diesterification reactor being configured to receive a diesterification alcohol stream comprising an alcohol having 1 to 3 carbon atoms and the monoester stream from the monoesterification reactor, convert the monoester and alcohol to a diester, and provide a crude diester stream comprising the diester;
• one or more anion exchange resin columns, each comprising a crude diester inlet fluidly connected to at least one of the crude diester outlets of one or more of the diesterification reactors, an anion exchange resin, and a deacidified diester outlet, each anion exchange resin column being configured to receive the crude diester stream from one or more of the diesterification reactors, pass the crude diester stream through the anion exchange resin to form a deacidified diester and an acidified resin, and provide a deacidified diester stream comprising the deacidified diester;
• and
• a hydrogenation reactor comprising a deacidified diester inlet fluidly connected to at least one of the deacidified diester outlets of one or more of the anion exchange resin columns, a hydrogenation catalyst, a hydrogen-containing gas mixture input, and an oxygenated hydrocarbon outlet, the hydrogenation reactor being configured to receive the deacidified diester stream from one or more of the anion exchange resin columns and a hydrogen-containing gas mixture, hydrogenate the diester, and provide an oxygenated hydrocarbon stream comprising an oxygenated hydrocarbon,
• wherein the oxygenated hydrocarbon is at least one selected from the group consisting of tetrahydrofuran, 1,4-butanediol, and gamma butyrolactone.
