Remote and Automatic Main Line Valve Technology Assessment

The capabilities of current automatic and remote-controlled valves for natural gas transmission pipeline break control are documented. The reliability of current break detection methods is limited due to the difficulty in distinguishing a line break from other transient operating conditions.

Summary:
The capabilities of current automatic and remote-controlled valves for natural gas transmission pipeline break control are documented. The reliability of current break detection methods is limited due to the difficulty in distinguishing a line break from other transient operating conditions. Simulation models show that more sophisticated approaches of applying existing sensors can be used to improve the reliable detection of pipeline breaks and therefore improve the effective use of line break controls. These approaches, specific for given pipeline configurations, involve the monitoring of different pipeline operating conditions, both at and away from the valve site. Further improvements could be expected from development of novel sensors that can better discriminate when a pipeline break occurs, continued development of "intelligent" valves with distributed measurement and control features, and increased automation and telecommunication capabilities. Appendixes present calculations, modeling, and analyses.
