Abstract:
     In the bottom of the tower, all the materials including ammonia, CO2, ammonium carbamate, etc. enter into the tower through respective fluid distributor, so that the material liquid is distributed homogeneously in the whole section once entering into the tower, and this can eliminate radically the distribution inhomogeneity of the flow rate, concentration and temperature of the materials. At the main urea discharge port in the upper part of the tower and at the discharge port for small amount of urea in the lower part, fluid distributors are set for homogeneous discharge. All the section homogeneous distribution of liquid flow in the tower can realize the homogeneous distribution of material residence-time and high reaction percent conversion.
