Distributed Control System Application for Distillation Column
ABSTRACT
The entangled nature of various continuous production processes, such as chemical processing, oil and gas, and water treatment, continue to require the advanced process control capabilities of the Distributed control system (DCS) in order to aggregate and analyse a large amount of data at the same instant of time. This paper aims to enhance the flexibility in controlling and monitoring of distillation column by configuring and developing a HMI using DCS with SCADA. DCS provides high scalability, solutions to complexity, redundancy, high adaptability to frequent process changes, hybridized to incorporate PLCs and PCs to control complex functions and to provide reporting services. Hence the optimized control of distillation column has been achieved via DCS.
