针对当前TRT两种不同的典型工艺布置，对带与不带启动阀的两种TRT升速过程进行了比较，并分析了差异原因。针对转速控制，推荐带启动阀的TRT工艺布置。%Regarding the existing two different types of TRT process layout, the two TRT speeding up processes with and without starting valve are compared while the reason for the difference is analyzed. For speed control, TRT process layout with starting valve is recom-mended.
