Numerical Simulation for Optimum Seeding Operation Using Liquid Carbon Dioxide

A Numerical Model to Investigate Optimum Liquid Carbon Dioxide Seeding Rate in Weather Modification Projects

Encapsulated liquid sorbents for carbon dioxide capture.

Drawbacks of current carbon dioxide capture methods include corrosivity, evaporative losses and fouling. Separating the capture solvent from infrastructure and effluent gases via microencapsulation provides possible solutions to these issues. Here we report carbon capture materials that may enable low-cost and energy-efficient capture of carbon dioxide from flue gas. Polymer microcapsules compo...

Removal of Water for Carbon Dioxide-based Egs Operation

CO2-based Engineered Geothermal Systems (EGS) have been explored from the perspectives of thermodynamic performance, in-reservoir chemical reactivity, and economic viability. Previous works have correctly noted the important role that initial water content in the geothermal reservoir will play in determining the viability of the concept, but have not examined reservoir water content from a quan...

Stability of dense liquid carbon dioxide.

We present ab initio calculations of the phase diagram of liquid CO(2) and its melting curve over a wide range of pressure and temperature conditions, including those relevant to the Earth. Several distinct liquid phases are predicted up to 200 GPa and 10,000 K based on their structural and electronic characteristics. We provide evidence for a first-order liquid-liquid phase transition with a c...
