  • SYSTEM AND APPARATUS FOR CREATING A LIQUID CARBON DIOXIDE FRACTURING FLUID
    Publication number: 20180128092
    Abstract: A method, system, and apparatus required for creating a mixture of dry proppant and liquid carbon dioxide (LCO2) for fracturing oil and gas formations is presented. The operation includes making a mixture of dry proppant and liquid carbon dioxide (LCO2) for use in a fracturing operation by supplying dry proppant that is pressurized to between 75 and 600 psia with a gas; further supplying a stream of sub-cooled LCO2 having a pressure substantially equal to that of the pressurized dry proppant; and adding dry, pressurized proppant to the stream of sub-cooled LCO2, thereby forming a mixed LCO2 and proppant fracturing slurry.

  • Purifying carbon dioxide using activated carbon
    Patent number: 8282715
    Abstract: Carbon dioxide-containing feed stream such as flue gas is treated to produce a high-purity carbon dioxide stream by a series of steps including removing SOx and NOx with activated carbon, carrying out subambient-temperature processing to produce a product stream and a vent stream, and treating the vent stream by pressure swing adsorption or by physical or chemical absorption to produce a product stream which is recycled to the feed stream.
