Baytown Cogeneration Project

The Baytown Cogeneration Project installed a GE 7FA gas turbine generator that produces 160 MW of electricity and 560-klB/hr of superheated 1500-psig steam. All of the steam and electricity are consumed by the ExxonMobil Refinery & Chemical Plant Complex. Small sales of electricity are possible in winter months. The new Cogen Unit allowed the complex to shutdown three inefficient, 1960’s vintage, steam and electricity generators to improve steam and power generation efficiency and to reduce environmental emissions. The 1500-psig steam generated by Cogen reduces the firing on the conventional boilers which are used in the olefins plant to drive extraction/condensing steam turbines. The lower pressure extracted steam is both used within the olefins plant and exported throughout the refining/chemicals complex
