到目前为止,苏联石油炼制和石油化学工业过程的控制有如下特征:即工艺装置的操作是根据温度、压力和流量等間接参数,用稳定这些参数的办法来控制。这种方法用人工方式来改变自动調节器的規定值,通常需2—5小时,这种校正主要决定于操作工的技术水平和經驗,它的迟緩性很大,而且經常达不到过程的最适宜条件。最近期間,苏联和其他一些国家采用自动取样和用工业自动質量分析器直接在流动过程中测定原料、半成品、成品和試剂的物理化学性能的方法,来实現工艺过程控制和操縱自动化。
So far, the Soviet Union’s petroleum refining and petrochemical industrial process control has the following characteristics: The operation of the process plant is controlled by means of stabilizing these parameters based on indirect parameters such as temperature, pressure and flow. This method manually changes the value of the automatic regulator, usually 2-5 hours, this correction mainly depends on the technical level and experience of the operator, it is very slow, and often can not reach The most suitable conditions for the process. In the recent period, the Soviet Union and other countries have adopted automatic sampling and methods for determining the physico-chemical properties of raw materials, semifinished products, finished products and reagents by means of automated industrial mass analyzers directly in the process of flow control for process control and automation.
