Innovative intelligent DCS based method for tank gauging control system in large oil terminal

The introduction of microprocessor-based plant control occurred shortly before 1980 with simple single-loop controllers. This technology quickly evolved into a DCS with control processor redundancy, high-density input/output systems, and a human machine interface (HMI). Today´s tank management plans are faced with intense pressure to improve storage reliability. Thereby, current business goals focus on increasing operational efficiency and overall equipment effectiveness. In support of this, a tool used to identify production loss and asset availability. Third-generation DCS employ powerful object-oriented design technology to enable efficiency improvements within daily operations and maintenance (O&M) activities. Additionally, advanced process optimization technology is added to support improvements in process efficiencies. Control system technology also now integrates several fieldbus protocols, thus enabling more flexible plant designs as well as improved data for maintenance. In this paper, the Innovative, modernization, design, integration, development and implementation of 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.
