摘要:
介绍了浙江石油化工有限公司采用美国UOP公司开发的Butamer工艺的 C4 反异构化技术新建的0.05 Mt/a异丁烷反异构装置，并总结了其在100 %和110 %设计负荷工况（以下分别简称为工况1#、工况2#）下的运行及标定情况。结果表明：在异丁烷原料性质相近的前提下，在上述2种标定运行工况下，不仅前、后置异丁烷反应器入口温度均低于相应的设计值，而且该装置的正丁烷终产品收率（≥94.67%）和产品中的正丁烷体积分数（≥88.93%）均高于相应的设计值，异丁烷及C≥5组分体积分数、含硫量、总含氯量等均低于相应的设计值；在工况1#、工况2#下的综合能耗较设计值分别降低了660.40，888.95 MJ/t。
Abstract:
The newly built 0.05 Mt/a isobutane anti-isomerization unit with C4 reverse isomerization technology was introduced，which belonged to the Butamer process developed by UOP company，USA. And its operation calibration under 100% and 110% of the design load conditions (hereinafter referred to as working condition 1# and working condition 2#，respectively) were summarized. The results showed that，upon the conditions of similar properties of isobutane raw feedstock，meanwhile under the above two calibration operating conditions，not only the inlet temperature of both the pre-isobutane reactor and the post-isobutane reactor were lower than the corresponding design index，but also both the yield of n-butane final product (≥94.67%) and the volume fraction of n-butane in the products (≥88.93%) were higher than the corresponding design index，moreover，volume fraction of iso-butane and C≥5 components， sulfur content and total chlorine content were all less than the corresponding design index. In comparison with the design index，its comprehensive energy consumption in working condition 1# and working condition 2# reduced by 660.40，888.95 MJ/t，respectively.
