摘　　要：从工艺参数、结构参数、投资和操作费用等几方面对500 kt/a连续重整装置采用缠绕式与管壳式进料换热器进行了对比,结果表明,前者多回收热量4.55%,进料加热炉负荷减少1.23 MW,反应产物空冷器负荷降低1.34 MW,装置投资增加12.5×10~4 RMB$,单位能耗降低122.65 MJ/t。采用缠绕式换热器操作费用一年可节约258.3×10~4 RMB$,投资增加的成本不到一月即可回收,而且更为环保。The twisting-tube heat exchanger and shell-tube heat exchanger were compared in respect of process parameter,construction parameter,capital investment and operating cost,etc for a 11 600 b/d continuous catalytic reformer.The results showed that the twisting tube heat exchanger was 4.55%higher in heat recovery, 1.23 MW lower in feed heater duty,1.34 MW lower in reactor effluent air cooler duty,125,000 Yuan(RMB)greater in capital investment and 122.66 MJ/t lower in unit energy consumption.If the twistingtube ...
