ABSTRACT:
A liquid absorbent is contacted with and atomized by an aromatics-laden gas resulting in transfer of the aromatics from the gas to the absorbent. The gas and aromatics-laden absorbent are then separated, and the aromatics-laden absorbent is collected. The aromatics may be obtained from an aromatics-bearing material, including vegatable materials such as roast and ground coffee, for example, by contacting the aromatics-bearing material with a gas.
