Abstract
Abstract A rectifying tower having a laminate of rectifying elements filled with waved fins between vertical main partition plates in which each rectifying element has an auxiliary partition plate having a smaller area than that of the main partition plate which is partially disposed vertically between two opposite main partition plates in respective rectifying elements, a gas-liquid contacting chamber in the space formed between portions of two opposite main partition plates not having an auxiliary partition plate therebetween, a distribution chamber in the space formed between the auxiliary partition plate and one of the two main partition plates, and a heat transfer chamber in the space formed between the auxiliary partition plate and the other of the two main partition plates, having passage sealed from the gas-liquid contacting chamber and the distribution chamber. Thus, preferably rectifying operation of a wetted wall type tower is always conducted regardless of the amount of raw fluid involved.
