Introduction to Process Control

Introduction to Process Control Lecture 1, 2016/2017. Control & System Eng. Dept. , 4th year Subject: Process Control . Dr. Safanah M. Raafat REPRESENTATIVE Process . Control PROBLEMS. Process : The conversion of feed materials to products using chemical and physical operations. In practice, the term Process tends to be used for both the processing operation and the processing equipment. Note: this definition applies to three types of common processes: continuous, batch, and semi-batch Continuous Processes Tubular heat exchanger. A Process fluid on the tube side is cooled by cooling water on the shell side. Typically, the exit temperature of the Process fluid is controlled by manipulating the cooling water flow rate.

composition for Process (c), a thermal cracking furnace. The specification of CVs, MVs, and DVs is a critical step in developing a control system. ... flow rate is maintained by a pump, and "ambient conditions," such as temperature in the unit, are controlled by adjusting a …
