Abstract

An apparatus for dividing the vapor and liquid components of a two-phased flow of anhydrous ammonia includes an upper chamber, a lower chamber and a partition member interposed between the upper and lower chambers. The partition member includes walls defining an aperture between the upper and lower chambers. At least one vapor outlet extends through the top of the upper chamber, at least one liquid outlet extends through the bottom of the lower chamber, and at least one two-phase inlet extends through the lower chamber disposed to admit two-phase flow in tangential relation to an internal surface of the lower chamber.
