Abstract: A separator assembly (30) for an evaporator comprises an ensemble of spaced-apart corrugated vanes (31) mounted in a hollow cylindrical configuration at the outlet (22) of the evaporator. The spacing between adjacent vanes (31) is such as to prevent line-of-sight passage of vapor between adjacent vanes (31) from the outer wall (33) to the inner wall (34) of the ensemble. The upper end of the ensemble of vanes (31) is secured to an annular support member (32), which is secured to the evaporator circumjacent the outlet (22). A closure member (40) is secured to the lower end of the ensemble. The annular support member (32) and the closure member (40) prevent vapor from leaving the evaporator via any path other than tortuous path between adjacent vanes (31) in a direction from the outer wall (33) to the inner wall (34). Droplets entrained in the vapor passing through the separator assembly (30) impinge upon the vanes (31) and are thereby separated from the vapor.
