**3. Conclusion**

In this chapter, a newly developed self-heat recuperation technology, in which not only the latent heat but also the sensible heat of the process stream can be circulated without heat addition, and the theoretical analysis of this technology were introduced. Several industrial application case studies of the technology were then presented and compared with their conventional counterparts. Although these processes require the power to circulate the process self heat instead of fuel for the furnace heater, a large amount of the energy required can be eliminated. Furthermore, to integrate the proposed self-heat recuperative processes with power generation plants, some amount of the power required can be generated from surplus fuel and energy, leading to achievement to co-production of products and power. Finally, this self-heat recuperation technology is a very promising technology for suppressing global warming and reducing the use of fossil fuels.
