Disclosed is an improved process for recovering condensable components from a gas stream, in particular, heavier hydrocarbons from a gas stream. The present process uses solid adsorbent media to remove said heavier hydrocarbons wherein the adsorbent media is regenerated in a continuous fashion in a continuous adsorbent media counter-current regeneration system using a stripping gas to provide a regenerated adsorbent media and a product gas comprising heavier hydrocarbons from a loaded adsorbent media. The improvement is the use of a portion of the product gas from the regeneration unit as the stripping gas.

Provided is a method of carbon capture, the method comprising: a) providing a solid sorbent in a fluidized bed reactor; b) fluidizing the solid sorbent by flowing air comprising CO.sub.2 through the fluidized bed reactor, wherein at least a portion of the CO.sub.2 is adsorbed onto the solid sorbent; and c) refluidizing the solid sorbent having CO.sub.2 adsorbed thereon by flowing an inert fluid through the fluidized bed reactor; and d) irradiating the fluidized solid sorbent having CO.sub.2 adsorbed thereon with microwave irradiation, thereby desorbing at least a portion of the captured composition from the fluidized solid sorbent.

Methods and systems for carbon dioxide removal are disclosed herein. In some embodiments, a representative carbon dioxide removal apparatus includes a web with a sorbent configured to absorb carbon dioxide and a drive system operably coupled to the web. The drive system can transport the web from a first zone, in which the web is exposed to gas, to a second zone, where the first zone is at a first temperature and the second zone is at a second temperature greater than the first temperature. The apparatus can further include a heating mechanism configured to increase a temperature of the second zone at least to the second temperature. This causes the removal of fluid including carbon dioxide from the web within the second zone.

The present invention relates to a drying apparatus capable of regenerating an adsorbent used for drying using microwaves. The drying apparatus of the present invention is formed to include a microwave irradiation means configured to irradiate microwaves to the adsorbent in a plurality of reaction towers in which the adsorbent adsorbing moisture or carbon dioxide is embedded, and when regenerating the adsorbent, directly heats the adsorbent using microwaves, thereby shortening a heating time and securing a sufficient cooling time, resulting in the effect of reducing the amount of dry air consumed for cooling and further increasing the drying efficiency.
