Abstract: A process and apparatus of separating CO2 gas from industrial off-gas source in which the CO2 containing off-gas is introduced deep within an injection well. The CO2 gases are dissolved in the, liquid within the injection well while non-CO2 gases, typically being insoluble in water or brine, are returned to the surface. Once the CO2 saturated liquid is present within the injection well, the injection well may be used for long-term geologic storage of CO2 or the CO2 saturated liquid can be returned to the surface for capturing a purified CO2 gas.

Abstract: A process of manufacturing cement clinker is provided in which a clean supply of CO2 gas may be captured. The process also involves using an open loop conversion of CaO/MgO from a calciner to capture CO2 from combustion flue gases thereby forming CaCO3/CaMg(CO3)2. The CaCO3/CaMg(CO3)2 is then returned to the calciner where CO2 gas is evolved. The evolved CO2 gas, along with other evolved CO2 gases from the calciner are removed from the calciner. The reactants (CaO/MgO) are feed to a high temperature calciner for control of the clinker production composition.

Abstract: Disclosed is a process for manufacturing underground caverns suitable in one embodiment for storage of large volumes of gaseous or liquid materials. The method is an acid dissolution process that can be utilized to form caverns in carbonate rock formations. The caverns can be used to store large quantities of materials near transportation facilities or destination markets. The caverns can be used for storage of materials including fossil fuels, such as natural gas, refined products formed from fossil fuels, or waste materials, such as hazardous waste materials. The caverns can also be utilized for applications involving human access such as recreation or research. The method can also be utilized to form calcium chloride as a by-product of the cavern formation process.
