Abstract
The present invention relates to a method for continuously obtaining carbon dioxide from a carbon-dioxide containing atmosphere, in which a fibrous carrier material charged with polyethylene imine is guided alternately through at least one adsorption zone and at least one desorption zone. In addition, the present invention relates to a device by which the method according to the invention can be carried out.
Claims19
A method for continuously obtaining carbon dioxide from a carbon-dioxide containing atmosphere, the method comprising the steps of guiding a fibrous carrier material charged with polyethylene imine alternately through at least one adsorption zone (A) and at least one desorption zone (D), wherein the at least one desorption zone (D) is heated at least in portions to a temperature of more than 30° C.,
- wherein the carrier material adsorbs carbon dioxide from the carbon-dioxide containing atmosphere at room temperature and normal pressure in the at least one adsorption zone (A), and emits the same in the at least one desorption zone (D) at a temperature which is higher than room temperature and/or at a lower carbon dioxide partial pressure than normal conditions.
A device for obtaining carbon dioxide from a carbon-dioxide containing atmosphere, comprising a fibrous carrier material charged with polyethylene imine, an adsorption zone (A) and a desorption zone (D), wherein the desorption zone (D) has at least two spatially separate gas outlets, which are each connected to a respective suction device,
- wherein the desorption zone (D) comprises at least one heating device and/or at least one device for pressure reduction and/or a stripping gas feed, and wherein the fibrous carrier material charged with polyethylene imine is movably tensioned over a number of support and/or deflection rollers, which are arranged in the adsorption zone (A) and/or in the desorption zone (D).
A method for continuously obtaining carbon dioxide from a carbon-dioxide containing atmosphere, the method comprising the steps of guiding a fibrous carrier material charged with polyethylene imine alternately through at least one adsorption zone (A) and at least one desorption zone (D), wherein the at least one desorption zone (D) comprises several portions at different temperatures (T, T′, T″),
- wherein the carrier material adsorbs carbon dioxide from the carbon-dioxide containing atmosphere at room temperature and normal pressure in the at least one adsorption zone (A), and emits the same in the at least one desorption zone (D) at a temperature which is higher than room temperature and/or at a lower carbon dioxide partial pressure than normal conditions.
