摘要： The present invention describes a method of removing ammonia from alcoholic solution in the presence of carbonic acid compounds while avoiding fouling by supplying the solution to be separated to the upper part of a distillation column and adjusting the temperature at the introduction point such that the ammonium salts of the carbonic acid compound in question are soluble in the in question at the top of the distillation column under the operating conditions.
