Abstract
A process for producing a coagulated latex is disclosed which comprises spraying into a coagulating chamber a suspension liquid or a high polymer latex to disperse as droplets, simultaneously spraying a coagulant into the chamber in the form of gas or mist, introducing into the chamber super-heated steam to heat dispersed droplets of the suspension liquid or the high polymer latex and the coagulant, collecting coagulated particles in a film-like flow of water or an organic solvent flowing downward along side walls and the bottom of the chamber, and recovering the coagulated particles. Also disclosed is an apparatus used for practicing the foregoing process which comprises a spraying means of a suspension liquid or a high polymer latex into a coagulating chamber, a spraying means of a coagulant, a distributing means of a downward flow liquid which forms a film-like flow of water or an organic solvent covering side walls of the chamber, a means for heating and rectification by which super-heated steam is introduced and the flow of atmosphere in the chamber is rectified, a gas-liquid contacting means which brings the downward flow liquid into contact with an exhaust gas, and a means for removing slurry containing coagulated particles.
