解析化工生产中复杂过程控制系统的控制方案的选择与运用

摘要

化工工业生产过程尤其是现代化工工业生产过程都是复杂的过程,往往由许多子过程串、并联组成,虽然生产工艺千变万化,但其控制方案却是相似的.因此掌握复杂过程控制系统的不同控制方案的区别及各自的特点对于现在的工程师和技术员来说就显得越发重要.%The complexity and sub-processes with serial and parallel composition jointly characterize the chemical production which has similar control schemes. Knowing various xontrol schemes and their differences well of the complex control system becomes important to both engineers and technicians.
