Design of CO2 Thickeners and Role of Aromatic Rings in Enhanced Oil Recovery Using Molecular Dynamics
Source abstract
Abstract
Oligomers of PDMS (M1), polyFast (M2), modified PVEE (M3 and M4), and two new molecules with cyclic cores (M5 and M6) were studied to understand their ability to thicken the sc-CO 2 at 377 K and 55 MPa, without any cosolvent. It was observed that PDMS and polyFast behaved in the known ways. PDMS does not improve the viscosity of the system without a cosolvent and PolyFast enhances the viscosity by a large margin. M3 and M4 also have not improved the viscosity significantly even with the introduction of a styrene component, but which has improved their solubilities in the fluid. M5 and M6, however, are observed to have enhanced the viscosity similar to that of polyFast due to their structural advantage and π–π interactions between the molecules. These molecules were also tested for their synthesizability, and their synthesis is found to be moderately easy.
