石油七厂洗滌工段原有流程有一系列缺点:如切废酸时易带走油,而这些油又要回收,所以浪费了劳动,而且降低了油收率,又因为切废酸是在开口的容器內进行,所以瓦斯很大,影响环境卫生;一人在切废酸时需另一人在废酸罐旁看着,所以需佔用两个劳动力。在轟轟烈烈的技术改造运动中,职工們針对这些缺点提出了許多建議,将洗滌流程作了改进,改进后的流程如下图所示。流程改进后,切酸时工人再不必在废酸罐旁看着,因而省去了一名工人。切废酸时被带走的油,在中間罐中因比重与前者不同而分开,又回到洗塔,因此消除了跑油,油收率提高了0.3—0.4％。
Oil Seventh Plant washing section of the original process has a series of shortcomings: such as cutting waste acid easy to take away oil, and these oils have to be recycled, so wasting labor, but also reduce the oil yield, and because the waste acid is cut open Therefore, the gas is very big, affecting the sanitation. When one person needs to cut waste acid, another person needs to look at the waste acid canister, so it takes two labors. In the vigorous technical reform campaign, workers made many suggestions on these shortcomings and improved the washing process. The improved process is shown in the figure below. After the process is improved, workers who cut the acid do not have to look at the waste acid cans any more, thus eliminating the need for a worker. Cut off the acid was taken away when the oil in the middle of the tank due to the difference between the former and the difference between separate and return to the washing tower, thus eliminating the running oil, oil yield increased by 0.3-0.4%.
