Abstract
This paper based on 180,000 tons of synthetic ammonia and 300,000 tons of urea Manufacturing Process of Henan Heartbeat Chemical Company ,which is born by Zhejiang soupcon Co., LTD. The paper used the 300,000 tons of urea manufacturing process control system as the main of research object, designs the homologous possibility of project, which based on the most commonly used DCS control and the implementation of the project approach.
Expound clearly the development of the DCS, and the basic structure and the work principle of the DCS and the application at the industry spot of last years, analyzed emphasesly characteristic and constitutes of ECS-100 DCS Zhejiang soupcon Co., LTD. The thesis mostly introduced application of the DCS to urea manufacturing process , and the DCS control, including the control scheme of the DCS design, the controller configuration of the system, and the whole course of the engineering actual and so on.
Based on the analyzed and design’s point of the distributed control system, according to practicality request, the paper designs the data collection system, communication system and computer disposal system based on the computer monitor and control system’s function request. In the end the design gave the system’s deficiency and the method to ameliorate it according to the result based on the field.
Keywords: DCS , urea, control scheme , configuration
