Optimal synthesis of fuel gas networks for energy sustainability Conference Paper uri icon

abstract

  • The optimal synthesis of a fuel gas network (FGN) with practical features, e.g., auxiliary equipment, non-isobaric and non-isothermal operation, non-isothermal mixing, nonlinear fuel quality specifications, fuel/utility costs, disposal and treatment costs, and emission standards, is put forward. A nonlinear program based on a superstructure that includes essential equipment, e.g., compressors, valves, and utility heaters/coolers, is developed. Alternatives for heating/cooling, moving, mixing, and splitting are then highlighted. The model is applied to real-life case studies from LNG and refinery industries to demonstrate that an FGN can save 40-50% of total energy cost of a plant and reduce fuel-from-feed or fuel-from-product consumptions by similar amounts. The issue of retrofitting new sources of fuel into an existing FGN is also examined. Moreover, the use of optimal FGN synthesis in reducing the energy cost of fuel-using and energy-intensive chemical plants is elucidated. This is an abstract of a paper presented at the 2011 AIChE Annual Meeting (Minneapolis, MN 10/16-21/2011).
