Development and evaluation of micro/nanomaterials obtained from Colombian organic waste and biomass for enhanced CO2 capture and geo-storage process at shallow reservoirs conditions (e-CCS) or conventional CCS at deep reservoir conditions (CCS).
Resumen
The Carbon Capture and Storage process (CCS), could potentially mitigate CO2 emissions emitted from industry by 22% by 2035 (IEA, 2011). Its global implementation, however, has been impeded mainly due to technical-economic considerations related to two main stages: 1) economic separation of CO2 from flue gas using absorbent solids , as at present on-surface separation stage represent 70-80 % of the total cost of CCS projects and; 2) CO2 injection in deep geological deposits (more than 800 m) under super critical conditions in a porous medium (Figure 1-a). The Colombian research group Phenomena Surface-Michael Polanyi have proposed an enhanced configuration of CCS (e-CCS) at shallow reservoir (less than 300 m) (Figure 1-b). In e-CCS, the entire industrial flue gas stream is injected directly into a reservoir, and the selective separation of the CO2 is carried out in-situ underground. In this novel concept, the CO2 remains in a gaseous phase , and selective adsorption controls the capture and storage processes. To further enhance the selective adsorption process and, however, it is essential to modify the surface conditions of chosen reservoir rock formation to enhance the molecular interactions. The modifying agent (micro/nanomaterial) must also conserve the naturally porous structure of this deposit site to avoid operational problems. But where to source these necessary absorbents? One solution is organic residues from agricultural production that left as organic waste or biomass in some cases represent social, health, and environmental problems. These products, however, that have potential to be used for carbon micro/nanomaterials production, especially those that have a high carbohydrates content to make ideal sorbens. Agriculture is integral part of the Colombian economy, where there are large producers of cane, rice, corn, fruits, among others, but several production chains have problems, some of them related to waste management while some areas have been vulnerable to violent conflict. This proposal therefore includes four main research lines towards the identification and development of the novel concpet: 1) Identification and characterization of carbon micro/ nanomaterials derived from agricultural waste and biomass; 2) Evaluation of material performance as sorbents at e-CCS/CCS process conditions, 3) Simulation of the e-CCS process under different conditions, e.g physicochemical characteristics of reservoirs and initial gas conditions, and; 4) Economic, environmental and technical evaluation. The last two activities would be innovative worldwide.
