醚化催化剂模块国产化节能降耗

Energysaving and consumption reduction of domestic etherification catalyst module

对比了轻汽油醚化蒸馏塔国产催化剂模块与进口催化剂模块的工艺条件、原料与产品性质、转换率和能耗,并作出简要的能耗核算。结果表明,相较于进口催化剂模块,国产化醚化催化剂模块可提高醚化蒸馏塔单元转化率约20%,降低低压蒸气用量3.98 t·h^(-1),每年可降低成本约794.9万元。

The process conditions,raw material and product properties,conversion and energy consumption of domestic catalyst module and imported catalyst module of light gasoline etherification distillation tower are compared,and a brief energy consumption accounting is made.The results show that compared with the imported catalyst module,the domestic etherification catalyst module can increase the conversion of etherification distillation tower unit by about 20%,reduce the consumption of low-pressure steam by 3.98 t·h^(-1),and reduce the cost by about 7.949 million CNY per year.
