| 20090101050 | METHODS AND SYSTEMS FOR REDUCING CARBON DIOXIDE EMISSIONS - A reduced emission kiln is described. In some embodiments, the kiln includes a combustion zone for generating heat energy. The combustion zone includes an oxygen inlet and a fuel inlet. In some embodiments, the kiln also includes a calcination zone for converting limestone into lime and carbon dioxide in response to the heat energy from the combustion zone. The calcination zone includes an inlet for limestone, a conduit for directing the carbon dioxide to the combustion zone for use as a flood gas to control the heat energy, an outlet for directing the lime to a hydration chamber, and a carbon dioxide permeable membrane for separating the carbon dioxide in the calcination zone from other materials in the calcination zone and preventing the other materials from entering the conduit for directing the carbon dioxide. | 04-23-2009 |
| 20090120288 | REMOVAL OF CARBON DIOXIDE FROM AIR - The present invention provides a method and apparatus for removing a contaminant, such as carbon dioxide, from a gas stream, such as ambient air. The contaminant is removed from the gas stream by a sorbent which may be regenerated using a humidity swing, a thermal swing, or a combination thereof. The sorbent may comprise a substrate having embedded positive ions and individually mobile negative ions wherein the positive ions are sufficiently spaced to prevent interactions between the negative ions. Where a thermal swing is used, heat may be conserved by employing a heat exchanger to transfer heat from the regenerated sorbent to an amount of sorbent that is loaded with the contaminant prior to regeneration. | 05-14-2009 |
