我厂酮苯溶剂脫蜡装置于1959年第一季度开工試車。通过全体职工們的努力和苏联专家的具体指导,开工比較順利,不到一周时間,便正式投入生产,而且处理能力和脫蜡油收率也很快达到设計要求。但由于我們对掌握这样自动化的大型装置的知識不够,对设计的先进性体会不深,尤其对設备的維护检修缺乏經驗,所以操作不平稳, I plant Ketone benzene solvent dewaxing device in the first quarter of 1959 started the test. Through the efforts of all staff and the specific guidance of Soviet experts, the project started smoothly and in less than one week formally put into production. Moreover, the processing capacity and the yield of dewaxed oil quickly reached the design requirements. However, due to our lack of knowledge of the large-scale installations that automate such systems, we have not had a deep understanding of the advanced nature of the design. In particular, we lack experience in equipment maintenance. Therefore, the operation is not stable,
