Abstract
PURPOSE: To prevent the foaming of bottom liquid in a liquid-vapor contactor, by installing an antifoaming plate in the lower liquid basin, and by adjusting the liquid depth above this antifoaming plate.
CONSTITUTION: The space between the bottom of packed layer of a packed column and its bottom liquid basin is separated into upper and lower parts by an inverted conical partition (antifoaming plate) 7; a vertical downtake 8 for introducing the absorbent solution into the bottom basin is installed in the center of this antifoaming plate 7; and a disk 9 is provided at the bottom outlet of the downtake 8. The foaming restricting effect can be further improved by operating the column so as to hold the absorbent solution above the antifoaming plate 7. The depth of absorbent solution above the antifoaming plate 7 is controlled to 200W500mm by installing a valve or an orifice in the downtake 8 or the preparing the downtake 8 in a form of one or several vertical U-tubes. It is desirable to operate the absorption column at high temperatures and with a low recycling rate of absorbent solution.
