The collapse of slack line regions may cause pressure surges that must be considered when developing operational procedures to avoid damaging the pipeline. Slack line regions significantly change the hydraulics of the pipeline operations, particularly the behavior of transients. Slack line flow behavior is of interest to pipeline operators for a number of reasons:įrictional head loss in slack regions is much greater than in tight line regions. On one large pipeline, slack volumes are in the tens of thousands of barrels. On others, slack line flow was expected as a normal part of the operation. Since the simulation software was not designed to handle the slack line flow, simulations during those periods were inaccurate. Again, the pipeline operators were unaware of this condition until real time simulation so&are was installed. On another, slack line flow occurred only during some upsets. In this case, the total slack volume (volume of vapor bubble) was only 50 to a few hundred barrels in size. However, until the real time simulation software was installed, the pipeline operators were unaware of its occurrence. On one, slack line flow existed almost all of the time. Slack line flow occurs only during abnormal pipeline operations.Įxperiences installing real time simulation software on a number of liquid pipelines over the last 15 years have included the following: Slack line flow occurs occasionally during normal pipeline operations. Slack line flow occurs all of the time in some section of the pipeline. Most liquid pipelines fall into one of the following categories: This flow condition is very common in liquid pipelines. Slack line flow is a phenomena in which a pipeline transporting a liquid product develops vapor bubbles at points at which the pipeline pressure falls below the vapor pressure of that liquid.
