Overview

Oil refineries are large scale plants. Due to the high capacity, many of the units are operated continuously at steady state for long periods of time. Producing varieties of petroleum products at high capacity while improving environmental and safety regulations is crucial to a refinery’s success. DCS (Distributed Control System) systems are deployed in complex oil refining processes, which allow the entire system of controllers to be connected by networks for communication and monitoring.

A sudden breakdown in the DCS system can be extremely costly for the production line, so the process control system must be designed with full redundancy to achieve high data availability and optimal manufacturing productivity. To enhance the safety of the operating environment, auxiliary networking systems that extend across the entire plant play an integral part in a plant’s safety.

Solution

Oil Refining Process

Dual redundant networks can be built with modular Ethernet switches, which offer multiple media and bandwidth configurations, and also leave room for future expansions. TNS industrial modular Ethernet switching solutions have DIN-Rail and rack mounting options that support Turbo Ring redundant technology (recovery time < 20 ms).

TNS oil refining network solutions feature high MTBF ratings with fan-less design, high-EMI noise immunity, redundant power supplies, and fiber optic support. All of these features allow long term stable operation in a refinery plant.

Auxiliary Systems Networking

Industrial rackmount Gigabit Ethernet switches deliver proven industrial reliability in a high port-density rack-optimized form factor, making it a perfect core switch in the control center. TNS Gigabit redundant Ethernet switches come with up to three Gigabit fiber ports, 2 Gigabit ports for redundant ring, and one Gigabit port for uplink.

Industrial-grade video encoders are capable of converting video from analog cameras to digitally compressed video.

Active Ethernet I/O delivers active, event-response-based reporting and control of I/O devices to the PC-based data acquisition and control field. Critical sensor data can be obtained immediately with real-time stamping. Instant event messaging by TCP, UDP, e-mail, and SNMP trap allows operators to respond immediately to exceptional situations.
