Addressing environmental problems is becoming an important initiative

throughout the world. The reduction of CO

emissions is a key element in

the path toward lowering the human contribution to climate change.

Many industrial processes generate waste energy that passes out of plant

stacks into the atmosphere and is lost.

Energy recovered from waste heat streams could supply part or all of the

electric power required by a plant, at no additional cost.

Therefore, heat recovery offers a great opportunity to conserve by

productively using this waste energy, to reduce overall plant energy

consumption and simultaneously decrease CO

emissions.

Power generation with zero additional emissions ORegen is a thermodynamic superheat cycle that recovers waste heat from gas turbine exhaust and converts it into electric energy. The thermodynamic cycle is based on an Organic Rankine Cycle (ORC). Heat from the turbine exhaust is transferred to a closed diathermic oil loop, which is used to heat an organic fluid loop. This lower temperature heat is then converted into useful work that can generate electricity.
