How would you design a cogeneration system for an industrial facility requiring both process steam and electricity?

Cogeneration system design requires analyzing thermal and electrical load profiles to determine the prime mover type. For steam-intensive loads, a backpressure turbine extracts steam at required pressure while generating power. For power-heavy loads, a gas turbine with HRSG provides flexibility. Key considerations include heat-to-power ratio matching, load following strategy (thermal or electrical), steam pressure/temperature requirements, and grid interconnection. Economic analysis should compare fuel savings against capital costs. Overall system efficiency of 70-85% is achievable versus 35-40% for separate generation.
