This invention is a method for improving dissolution efficiency in processes in which a feed fluid is introduced to a zone where it is contacted with a liquid solvent for preferentially removing a component of the feed and where part of the solvent so contacted undergoes transfer into the feed fluid to saturate the same. It has been found that such transfer significantly impairs dissolution efficiency. In accordance with the invention, an amount of the above-mentioned solvent is added to the feed fluid being introduced to the contact zone, the solvent being added in an amount sufficient to effect reduction or elimination of the above-mentioned transfer. Preferably, the solvent is added to the feed fluid in an amount saturating or supersaturating the feed fluid under the conditions prevailing in the contact zone.
A method for increasing dissolution efficiency in a process wherein a feed fluid including at least a first component and a second component is introduced to a zone where said fluid is contacted with a liquid solvent for effecting preferential dissolution of the first component and wherein part of said liquid solvent undergoes transfer into said fluid upon contact therewith to effect saturation of said fluid, said method comprising:
A method for increasing absorption efficiency in a process wherein a feed gas including at least a first gaseous component and a second gaseous component is introduced to a zone where said gas is contacted with a liquid solvent for effecting preferential absorption of the first component and wherein part of said liquid solvent undergoes vaporization on contact with said gas to effect saturation of said gas, said method comprising:
In the processing of a feed gas to recover a selected component thereof said gas including at least a first gaseous component, a second gaseous component, and vapor of a selected solvent, the concentration of said vapor in said gas being less than the concentration required to saturate the same, said gas being introduced to an absorption zone where it is contacted with the selected solvent in the liquid phase to effect preferential absorption of the first component, the improvement comprising:
In a continuous process wherein a stream of gas including at least a first gaseous component and a second gaseous component is mixed with a gas-recycle stream to form a stream of feed gas, said recycle stream containing vapor of a selected solvent in an amount insufficient to saturate said feed gas, said feed gas being introduced to a zone where it is contacted with said selected solvent in the liquid phase to effect preferential absorption of the first component, the improvement comprising:
A method for increasing dissolution efficiency in a process wherein a liquid feed including at least a first component and a second component is introduced to a zone where said feed is contacted with a liquid solvent for effecting preferential dissolution of the first component and wherein part of the liquid solvent undergoes transfer into said feed upon contact therewith to effect saturation of the same, said method comprising:
