By heatbalance analysis of the whole regenerative system, which is regarded as a closed thermodynamic system, the calculation model on the influence of HPs removal on heat economy of unit is derived.
The results showed that, the correlativity of the total unit energy consumption with the total yield of crude distillation is poor based on "heatbalance method" .
研究结果表明,以“ 热量平衡法”为计算基准的蒸馏单位能耗与总拔出率的线性关联性较差;
