Safety Instrumented System Ensures Safe Operation of Oil and Natural Gas Facilities

Yokogawa Electric Corp.  has released the enhanced ProSafe-RS safety instrumented system. This new version, ProSafe-RS R3.02.00, features input/output modules that will operate reliably in the high-temperature conditions typically encountered in desert locations. Support of an open communications protocol has also been added, enhancing ProSafe-RS’s compatibility with other vendors’ distributed control systems (DCS).

In the oil, natural gas, petrochemical, iron and steel, and other energy and basic materials industries, it is becoming increasingly important to ensure the safety of plant operations to prevent accidents, protect the environment and be good corporate citizens. Accordingly, there is a growing demand for safety instrumented systems that can detect abnormal conditions and safely initiate emergency shutdowns.

Yokogawa’s new modules can operate at ambient temperatures up to 70°C (158°F). This reduces the system footprint. ProSafe-RS has been enhanced by adding support for Ethernet-based Modbus/TCP communications with other systems. This facilitates the flexible connection of the ProSafe-RS system with distributed control systems from other vendors, allowing our customers a greater range of choice.

Applications include emergency plant shutdown and fire prevention/fighting in the oil, natural gas, petrochemical and other process industries.
