Downstream: Oil Refining and Petrochemical Operations
Ensure 24/7 Sustainable Production with Industrial Ethernet
Oil refineries are large-scale plants that process large quantities of crude oil and feature a complicated production process with a great number of intelligent equipment devices. Because of the high capacity, many of the units operate continuously for long periods of time. The distributed control system (DCS) is the main control system connected to the controller elements by Ethernet networks to manage and monitor the plant's output and performance. Since non-stop 24/7 operation is crucial to the entire process, the Ethernet network system must have reliable redundancy to achieve high data availability and optimal productivity. In addition, an auxiliary system is used to detect and track unsafe events, such as leaks, to maintain safe operations.
Network Requirements   Moxa Solutions
  • Build a highly reliable, flexible, yet cost-effective industrial Ethernet communication network for the entire DCS.
  • Dual redundant network for SCADA system, controllers, and field devices to simplify the task of providing maximum uptime for the critical oil refinery DCS process.
  • Fiber redundant ring networks over a vast area in the refinery plant to connect the field gas sensors, leak detectors, and other industrial detectors to the SCADA control room.
  • IP video surveillance and Ethernet I/O solutions integrated to the network to enable remote monitoring and control of daily operations, especially for emergency situations.
  • Cellular solutions to easily connect field devices in the remote site for mobile management.
  • High performance modular managed switches supporting 4 Gigabit RJ45/SFP ports, up to 24 fast Ethernet ports, and Turbo Ring/Turbo Chain redundant technology (recovery time < 20 ms) excel in building reliable redundant fiber optic connections for a heavy-load DCS process.
  • Moxa offers a vast range of industrial Ethernet switches with DIN-Rail or rack mounting options and fiber support, including high-port-density rackmount switches that are a natural fit for control centers, Gigabit Ethernet switches for video surveillance applications, and PoE+ solutions for cost-effectively connecting high power PoE-based sensors.
  • Industrial IP video encoders and event-based Active Ethernet I/O provides a valuable integrated service over one Ethernet platform for real-time data acquisition and remote monitoring.
  • Comprehensive device networking solutions, such as cellular IP gateways, serial-to-Ethernet fieldbus gateways, and Ethernet-to-fiber media converters, and more.
  • All of Moxa's solutions feature high MTBF, fanless, high-EMI noise immunity, and industrial design to enable durable operations.
