Iran-Made Smart Control System Installed in 20 Refineries, Petrochemical Plants
“Our product is one of the most reliable DCSs globally which has been installed in over 20 refineries and petrochemical plants in Iran and has been used for more than 10 years,” said Javad Khodatars, the market development manager of the company.
“The DCS is a fully digital system that provides the user with a single architecture with full functionality from a few inputs and outputs to tens of thousands of inputs and outputs to connect people, processes and production. This intelligent integration provides the right infrastructure for advanced applications, resulting in better efficiency and fewer undesirable changes in the process,” he added.
"Our product is mainly used in the Russian oil and gas industries, and we currently supply approximately 40 percent of the neighboring country's needs for this product," Khodatars said.
A DCS is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localizing control functions near the process plant, with remote monitoring and supervision.
Distributed control systems first emerged in large, high value, safety critical process industries, and were attractive because the DCS manufacturer would supply both the local control level and central supervisory equipment as an integrated package, thus reducing design integration risk. Today the functionality of Supervisory control and data acquisition (SCADA) and DCS systems are very similar, but DCS tends to be used on large continuous process plants where high reliability and security is important, and the control room is not geographically remote. Many machine control systems exhibit similar properties as plant and process control systems do.
