ABSTRACT:
This invention relates to a method for decreasing the pressure drop in a column used for contacting at least one gaseous stream and at least one liquid stream, wherein a portion of the pressure drop across the column is caused by foam. The method comprises injecting a non-foamable liquid into the gaseous stream at a location, in an amount, and at a temperature which are sufficient to decrease the total pressure drop across the column.
