Abstract:
Natural gas/NGL supply chains usually comprise extensive networks of compressor stations pipelines processing units and other facilities. Their operation involves many degrees of freedom impacting efficiency profitability and environmental performance. We present a novel methodology making use of detailed physics-based models to optimize network operation. Despite its underlying complexity the application of rigorous mathematical optimisation to detailed models of entire networks is now computationally tractable and can ensure that the solution obtained actually meets all constraints. The new methodology is applied to the natural gas network of Basrah Gas Company (a Shell Joint-venture in Iraq) demonstrating profitability improvements of 9%.
