摘　　要：应用多组分精馏原理,从设计角度对精馏装置运行的不稳定故障进行诊断,考察了回流比、回收率、进料温度和热状态对塔的加料位置和实际塔板数的影响;同时应用正交设计优化各工艺条件。方案为A501塔分离任务仍不变,将A502塔的高度由原来的2．2米增加到12米,加料板位置调整在8．5 m高度处;塔前增加一台换热器,控制进料温度150℃。操作数据证明:故障判断准确,处理有效,获得了较好的经济效益。Multi-compositions distillation column was diagnosed on the basis of principles of distillation. The relations were studied that ratio of reflux, rate of recover, temperature of input-material and hot-state effect on the input-material place and amount of column plate. The optimization was researched with method of orthogonal design. The optimization results were as below： The separating job of column A501 did not vary. The height of column A502 changed from original 2.2 m to 12 m. The input-material plate was located in the 8.5 m height of column. One heat booster was added in front of the column. The temperature of input material was controlled at 150℃. The conclusion demonstrates： Failure-diagnosis was right and economic benefit was good.
