Abstract: A central digital monitoring and control system (CDMCS) for the terpene chemicals pilot-plant equipments and their process flows is researched and developed, which includes a friendly man-machine operation interface, a combinatory real-time control system, integrated means for measurement and control of processing parameters, and functions which show and putout intelligent report forms and record curves. Based on analysing and studying the present conditions, situations and features of existing terpene chemicals pilot-plant process and equipments, the DCS techniques application and implementation solutions to the process and equipments are introduced for central monitoring control system integration as well as digitalization in this paper. The upgraded terpene chemicals pilot-plant which is integrated from equipments, process and CDMCS has been actually used in charge, and successfully run for 90 days. The results show that the system possesses high accuracy of monitoring and controlling, excellent reliability, satiability and convenience of operations, and provides highly qualitative processing test data as expected and designed.
