Abstract
This two-paper work focuses on a different approach for capture and reduction of CO2 from flue gases of fossil fired power plant, with respect to conventional post-combustion technologies. This approach consists of flue gases utilization as co-reactants in a catalytic process, the tri-reforming process, to generate a synthesis gas suitable in chemical and energy industries (methanol, DME, etc.). In fact, the further conversion of syngas to a transportation fuel, such as methanol, is an attractive solution to introduce near zero-emission technologies (i.e. fuel cells) in vehicular applications.
(And, of course, once we have the methanol, ExxonMobil's MTG(r) technology can convert it into gasoline for us. Or, it can be used in the manufacture of plastics and other useful materials, wherein the CO2 would be permanently sequestered.)
In this Part A, integrated systems for co-generation of electrical power and synthesis gas useful for methanol production have been defined and their performance has been investigated considering different flue gases compositions. In Part B, in order to verify the environmental advantages and energy suitability of these systems, their comparison with conventional technology for methanol production is carried out.
The integrated systems (ITRPP, Integrated Tri-Reforming Power Plant) consist of a power island, based on a thermal power plant, and a methane tri-reforming island in which the power plants' exhausts react with methane to produce a synthesis gas used for methanol synthesis.
The energy and environmental analysis of ITRPP systems (ITRPP-SC and ITRPP-CC) has been carried out by using thermochemical and thermodynamic models which have allowed to calculate the syngas composition, to define the energy and mass balances and to estimate the CO2 emissions for each ITRPP configuration.
The reduction in the CO2 emissions has been estimated in 83% ... (to) 84%."
So, we reduce Carbon Dioxide emissions by more than 80%, and we get liquid fuel in the bargain.
Nah. ... Nuts to that. Let's just gather it up and stuff it all down a leaky old oil well, instead.
