摘　　要：叙述了精馏塔进料位置对全塔效率的影响。认为不在最佳位置进料会导致全塔效率下降,而不是理论塔板数增多;不能用下移进料位置提高塔顶的含量,也不能用上移进料位置提高塔底的含量;工程设计中可在最佳进料位置附近几块塔板的塔圈上增设进料口,操作中可通过改变进料口使塔长期处于最佳工况。Effect of feed place of distillation column on the efficiency of the whole tower is discussed in this paper. The wrong feed place of distillation column will lead the whole tower efficiency going down, the theoretical number of plate will not increase at the same time. So the dropping of the concentration at the top against the rising at the bottom is a necessary result.
