Patent ES-358855-A1 (ES)
Title: Process for the Production of Urea having a Low Carbamate Content
IPC: C07C239/00
Filed: 1968-09-25
Abstract: Urea production comprises feeding gaseous CO 2 and an excess of liquid or gaseous NH 3 to a synthesis zone in a reactor, reacting the CO 2 and NH 3 therein so as to produce, as the reaction product, a solution of urea contaminated with ammonium carbamate and containing the excess NH 3 , causing or allowing the said solution to flow as a thin film over a surface in a decomposition chamber in which the temperature and pressure are substantially the same, heated to an extent sufficient to cause at least part of the ammonium carbamate to decompose into gaseous CO 2 and NH 3 , recycling the decomposition products as well as the excess NH 3 to the synthesis zone, and recovering the urea solution having a reduced ammonium carbamate content. The thin liquid film may be obtained, e.g. by allowing the reaction product to drop along the inside wall of a heat exchanger or along the wall of part of the reactor other than the synthesis zone. Synthesis and decomposition may be effected at a temperature of 180- 350 C. and pressure of 100-300 atm. The presence of NH 3 excess and consequent dissolved NH 3 in the solution from the synthesis zone is essential and the usual NH 3 /CO 2 ratio is from 2À3:1 to 5À5:1.

Title: Recirculation dialysate system for use with an artificial kidney machine
IPC: A61M1/16
Filed: 1970-06-25
Abstract: A recirculating dialysate system for use with an artificial kidney in which the total volume of dialysate solution is controlled. After leaving the artificial kidney, the urea in the solution is removed in a zirconium phosphate column containing urease and the other waste products are removed in a carbon column containing activated carbon and hydrated zirconium oxide. The solution passes through the dialysate reservoir (or container) where it was originally introduced and where the level of solution indicates the amount of fluid removed from the body. Downstream of the dialysate reservoir, the solution is reconstituted by the addition of magnesium and calcium (removed in the zirconium phosphate column) so that these substances will not be removed from the blood in the kidney. The rate at which water passes from the blood into the dialysate solution can be controlled by controlling the pressure of the dialysate solution on the dialysate side of the kidney membrane, so that sufficient water can be removed to arrive at water balance in the patient.
