This work throws the light on the environmental problems caused by carbon dioxide accumulation in the atmosphere, together with the energy crisis and the rapid depletion of the fossil fuels. Also, this effort proposes the solution for both problems by presenting new approach for capturing/converting CO₂ into liquid fuel methanol. The new approach seeks to reduce both, the fossil consumption and atmospheric CO₂ by recycling secondary CO₂ as a carbon source instead of using natural gas. Three models are suggested for converting carbon dioxide present in the large- scale flue gases streams emitted from electric power plants into liquid fuel methanol. Our work considers the CO₂ balance for the new technologies proposed taking into account all CO₂ flows from/to the environment. Three new process technologies are developed and modeled for converting CO₂ streams into methanol. The total cost of equipment and utility for all processes are compared. The energy targets as well as the CO₂ emissions (balance) are determined. Heat integration is performed on the best selected process technology
