Device and method for producing methyl ethyl carbonate per unit

The invention relates to the technical field of electrolyte organic solvent production, and discloses a device for producing methyl ethyl carbonate per unit. Comprising a circulating immobilized reactor, a reactive distillation tower, a methyl ethyl carbonate and diethyl carbonate separation tower, a methyl ethyl carbonate product tower, a dimethyl carbonate raw material feeding pipeline, an ethanol raw material feeding pipeline, a dimethyl carbonate and methanol azeotrope circulating reaction pipeline, a diethyl carbonate circulating reaction pipeline and a dimethyl carbonate circulating reaction pipeline, the dimethyl carbonate raw material feeding pipeline and the ethanol raw material feeding pipeline are connected to a feeding hole of the reactive distillation tower, and a tower kettle of the reactive distillation tower is connected to a feeding hole of the ethyl methyl carbonate and diethyl carbonate separation tower through a pipeline. By additionally arranging a dimethyl carbonate methanol azeotrope an
