Apparatus for dividing a gravity flow liquid stream into a plurality of separate streams of predetermined proportions comprising (a) a substantially vertical inner liquid inlet tube having a closed end, such end being that toward which the liquid is flowing, and this inner tube containing one or more substantially parallel vertically elongated openings beginning at the closed end of the tube, such openings being of such size as to cause a partial backup of liquid traveling toward the end of the tube; (b) a substantially vertical covering tube having a closed end and containing a plurality of substantially parallel vertically elongated openings, but offset from the vertically elongated opening or openings of the inner tube, and wherein the space between the inner surface of the covering tube and the outer surface of the inner tube, and the size of the vertical opening of the covering tube are such that a partial backup of liquid occurs between the inner tube and the covering tube; and (c) outlet means for collecting the liquid ammonia which passes out through the vertical openings of the covering tube into a plurality of separate streams.
