System and device for increasing the yield and the production potential of urea reactors

Abstract From the Canadian patent

System for increasing the yield and at the same time the production potential of reactors for urea formed by the, synthesis of ammonia with carbon dioxide at high pressure and temperature, the internal space of said reactors being run through cocurrently by a liquid phase and a gas phase and being divided into compartments to avoid the excessive mixing of the entire liquid phase and to allow the intermittent redistribution of the gas in bubbles of a suitable size for increasing the exchange of heat and matter between the two phases, characterized by the fact that at each passage from one compartment to the next the liquid phase and the gas phase are made to flow on separate routes and …
