The plant was designed to process associated gas – gas that is produced with crude oil – at a rate of 1.5 billion standard cubic feet per day (scfd).
Gas that enters the plant is first treated to remove carbon dioxide and hydrogen sulfide. This sweetened gas stream is then sent to dehydrators. After this process the gases are chilled to temperatures as low as -72 C. After the methane is stripped out, all that remains is natural gas liquids (NGL). This is then sent to Yanbu' and Ju'aymah for fractionation.
In 2011, we successfully installed the first Gas Treating Membrane Technology Plant at Shedgum Gas Plant. This pilot program studies the removal of nitrogen and acid gas contaminants, as well as the membrane’s durability and maintainability for sour gas services. We will complete performance tests by mid-2013.
Due to the scale and integrated design of the project, world-class gas processors have approached Saudi Aramco to collaborate on research and development of membranes.
We rolled out our Asset Performance Management (APM) program at the Shedgum Gas Plant to transform operations and maintenance through a proactive, integrated and performance-focused approach. The APM helped us identify areas for improvement and develop action plans to optimize plant performance.
Also at Shedgum and 'Uthmaniyah, we have upgraded 10 sulfur recovery units to increase sulfur recovery from 95 percent to 98.7 percent and to reduce sulfur dioxide emissions.
