Intelligent and innovative valve control DCS-based in large tank farm oil terminal

Control valves are used mainly within industrial plants to control operating conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers. The fully opening or closing of control valves is done by means of electrical, hydraulic or pneumatic systems. These control signals, more common now are 4-20mA signals for industry, 0-10V for HVAC systems, & the introduction of “Smart” systems, HART, Fieldbus Foundation, & Profibus being the more common protocols. Developing Distributed Control System is a major industrial concern since those systems are more and more complex and involved in many safety critical application fields. Third-generation DCS employ powerful object-oriented design technology to enable efficiency improvements within daily operations and maintenance activities. In this paper, the Innovative, modernization, design, integration, development and implementation of Valve Master Control Multi-Networking for a computer-based (DCS) tank gauging system for the Large Tank Farm is described. The complex included 37 storage tanks located at 10 different groups. Each group supports data collection on the pipeline computer located in the main control room. The new and modern tank level gauging systems incorporate Radar gauges for tanks, with transmitters for temperature and pressure. All types of these gauges offer an upgrade in performance and maintainability.
