Definitions

  • the present invention concerns a system and method for waste heat energy recovery or waste heat energy utilization .
  • waste heat is contained in the flue or exhaust gases of various industrial processes and the exhaust gases of different drives and engines and the net efficiency values in the discussion below are based on waste heat utilization from flue/exhaust gases. This is as distinct from waste heat utilization in solid bodies, such as solar collectors or some other high temperature solid structures, which may produce significantly higher values of net efficiency.
  • Waste heat can be utilized by turbine-generator systems which employ thermodynamic methods, such as the Rankine cycle, to convert heat into work.
  • this method is steam-based with the waste heat being used to raise steam in a boiler to drive a turbine.
  • a key short-coming of a steam-based Rankine cycle is its high temperature requirement; that is, it usually requires a relatively high-temperature waste heat stream (e.g. 300°C or higher) or a very large overall heat content.
  • the complexity of boiling water at multiple pressures/temperatures to capture heat energy at multiple temperature levels as the heat source stream cools is costly.
  • a steam-based Rankine cycle is not a practical option for streams of low flow rate and/or low temperature.
  • the organic Rankine cycle addresses short-comings of a steam-based Rankine cycle by replacing water with a lower-boiling-point fluid, such as a light hydrocarbon like propane or butane, or a HCFC fluid (e.g. R245fa) .

  • ORC organic Rankine cycle
  • widely implementing the organic Rankine cycle (ORC) technology does not permit a utilization of all the waste heat potential due to the limited thermal stability of the organic fluid, which affects thermal efficiency of ORC systems when the waste heat source temperature exceeds 250°-300°C.
  • the total net efficiency of existing ORC units does not exceed a value of about 10%, such that up to 90% of the thermal energy is still wasted to the atmosphere.
  • Supercritical carbon-dioxide (S-CO2) waste heat utilization technology has been used to address some of these issues.
  • the supercritical state of CO2 provides improved thermal coupling with multiple heat sources and allows for development of more effective (up to 20% net efficiency) and very compact units compared with ORC systems for a variety of applications.
  • Such S-CO2 systems often require very complex system layouts and unique heat transfer equipment, however, which lead to high capital costs and also technical difficulties. Examples ' of such known systems for waste heat recovery and utilization are described in the patent publications WO2011/119650A2, WO2012/074905A2, WO2012/074911A2, and WO2012/074940A2.
