分析了中低低工艺、全低变工艺和等温变换工艺的优缺点，讨论了变换装置中饱和热水塔设备的作用。依据变换工段具体改造实例，从工艺流程、蒸汽消耗、改造投资、操作等几方面，对等温变换工艺和全低变工艺进行了比较。
分析瞭中低低工藝、全低變工藝和等溫變換工藝的優缺點，討論瞭變換裝置中飽和熱水塔設備的作用。依據變換工段具體改造實例，從工藝流程、蒸汽消耗、改造投資、操作等幾方麵，對等溫變換工藝和全低變工藝進行瞭比較。
분석료중저저공예、전저변공예화등온변환공예적우결점，토론료변환장치중포화열수탑설비적작용。의거변환공단구체개조실례，종공예류정、증기소모、개조투자、조작등궤방면，대등온변환공예화전저변공예진행료비교。
The advantages and disadvantages of medium-low-low temperature shift process,total low temperature shift process and isothermal shift conversion process are analyzed,and the role of saturation hot water tower in shift conversion unit is discussed.Based on renovation examples of shift conversion processes,comparison is done with isothermal shift conversion process and total low temperature shift process in terms of process flow sheet,steam consumption,renovation investment and operation.
