Abstract
In a rectifying apparatus of vapor/liquid contact type, the rectifier 5 is disposed above a regenerator 4 and has two stages, a lower recovery stage and an upper condensation stage. The two stages are filled with filler elements 7a, 7b and 7c, 7d, respectively. Each filler elements 7a and 7c has a conical bottom for biasing the falling liquid towards its center and the rising refrigerant vapor towards its outer edge. The rising speed of the refrigerant vapor is made more uniform and the falling liquid has less tendency to drip down along the side wall. As the contact between the vapor and the liquid is increased, the efficiency of rectification is enhanced.
