In 2004 the management approved the phased replacement of all pneumatic field instrumentation and pneumatic control equipment. This allows us to achieve the desired high level of operating reliability and facilitates optimum process operations. In six phases, the plant is receiving new instrumentation unit by unit. The conversion of all instrumentation and control systems is mostly being conducted while the plant remains operational. That’s an achievement to be proud of. Completion of this major control-room modernization marks the finish of the re-instrumentation at the VCM plant.
