Patent ID: 10350510

Abstract:
What is described relates to cross-flow packing heat and mass transfer column vessels, where rectifying separation of liquid-vapor mixtures, distillation of liquid-vapor mixtures, and absorptive separation of liquid-vapor mixtures occur, and may be used in oil-refining, petrochemical, chemical, gas, food, and other industries. The proposed mass transfer column with cross flow of liquid and gas (vapor) phases includes shell, feed nozzle, distillate and residue withdrawal nozzles, nozzles of injection and withdrawal of auxiliary flows, cross-flow packing sections separated heightwise by horizontal baffles having, successively, in direction of gas (vapor) phase, in normal shell cross section, a window for gas (vapor) flowing on packing section inlet side and continuous area on packing section outlet side, which alternate on horizontal baffles neighboring by height, with liquid distributors between packing adjacent sections and above packing upper section, which consist of three successively mating parts: horizontal leaf, set of steps, and blind pocket.
