Case Studies

Case Study: Enterprise Products / Lower Colorado River Authority (LCRA)

Customer Challenge
When the Lower Colorado River Authority (LCRA) tapped Enterprise Products for LCRA’s gas-fired electric power plant in Horseshoe Bay, Texas, Enterprise contacted ATI. ATI applied a proprietary Gevalco pipeline automation solution to Enterprise for remote operation control of a mainline valve to protect LCRA assets and the environment.

Along with the remote opening operation, ATI incorporated an automatic Linebreak Control in case of a ruptured pipeline or an unusually high demand from the pipeline. The Linebreak Control has a manual reset which inhibits any opening operation after a linebreak condition has been reached. After normal operating conditions have been re-established, as an added security level, the control must be manually reset to engage any of the control features, giving further control to Enterprise and greater protection against unintended reset.

Previously only manually operated, the valve can now also be remotely operated which gives Gas Control in Houston the ability to operate the valve and get valve position feedback. The actuator operates using natural gas straight from the pipeline, which averages 600 psig at this location. The Linebreak Control compares the pipeline pressure with that of a reference tank and a calibrated orifice. Once the Rate of Drop reaches the set point of the control, it will automatically cause the valve to close.

The automation retrofit package provides savings in manpower, energy, and time. In this case, the nearest technician is a two-hour drive from the valve location. Enterprise now has more precise control and protection of their assets and the surrounding area of operation, without travel or additional manpower.

Technology Note
The design concept of this Gas Motor Actuator Control dates back to 1998 when Gevalco was asked by Texas Eastern Transmission Corporation for assistance with their RCV Project. At the time, Texas Eastern was also interested in assessing the effectiveness of remotely controlled valves on interstate natural gas pipelines and determining their technical and economical feasibility to shut off gas after a rupture.

In 2000, Gevalco was awarded a patent for these controls and has since been supplying gas transmission companies with a reliable, economical solution for automating existing and new mainline block valves. ATI acquired Gevalco in 2011.

Case Study: Excess Flow Control

ATI shipped fifteen hydraulic double-acting actuators with newly designed control systems on each of the units. A Houston-based valve automation center approached ATI to design a system to actuate and control the valves on a hydrogen pipeline. The control system is designed to sense a change of 7 psi differential pressure in a pipeline operating at 915 psi which would indicate excess flow and possibly a leak. If excess flow is detected, the actuator shuts the valve and stops the flow.

This is important because such an increase in differential pressure would indicate an increase in flow which may mean a leak downstream. Fast speed and fast response were critical in the design of these units.

Case Study: East Tennessee Natural Gas

In early 2003, East Tennessee Natural Gas commissioned the first-of-its-kind bi-directional station bypass at the Ooltewah, TN station. This system, developed and manufactured by Gevalco, was needed to fit the unique operating scenario created by the Patriot project to cross-connect three pipeline systems. The actuator controls provide an automatic opening of the station bypass valve based on pressure differential across the compressors.

The challenge was to provide the same control action when the flow direction was changed, thereby making the normal discharge pressure sensing point the suction pressure point under the reverse flow scenario. By making some unique modifications to the standard Gevalco “Station Bypass Control” system, the new control strategy was implemented seamlessly, requiring no operator changes when switching flow direction.

This system ensures the integrity of continuous operation under varying operating conditions. ETNG’s confidence with the system is evidenced by the purchase of 7 additional Gevalco “Bi-Directional Station Bypass Control” systems.
