The total heat load increases with the increase of reflux ratio; With the increase of reflux ratio, the methanol flow rate at the top of the tower decreases gradually, and the methanol loss rate decreases; With the increase of reflux ratio, the flow rate of MAL at the top of the column first decreases and then increases, and the recovery rate of MAL at the bottom of the column is the worst when the reflux ratio is 0.9. Considering the economy and rationality, the reflux ratio is 0.7.<br>
