Abstract: A chemical solution synthesis device comprises a chemical solution holding unit, a reaction vessel, a first chemical solution feed unit, a chemical solution feed and discharge unit, and a second chemical solution feed unit. The chemical solution holding unit is configured to hold a chemical solution. The chemical solution and carriers are reacted in the reaction vessel. The chemical solution is transferable from the chemical solution holding unit to the reaction vessel without coming into contact with atmosphere. The first chemical solution feed unit is connected to the reaction vessel and configured to supply the chemical solution to the reaction vessel. The chemical solution feed and discharge unit is provided vertically above the first chemical solution feed unit. The second chemical solution feed unit is configured to suppress adhesion of the carriers to the reaction vessel.

Abstract: A continuous falling film reactor includes a reactor body including chambers for a reaction between first and second reagents. The chambers have a respective inner surface, for the sliding of the first reagent in the form of a thin film, or layer, a device for introducing the first reagent, in particular in the liquid phase, especially in the form of an organic raw material, into the respective chamber and a device for inputting the second reagent, in particular in the gaseous phase, especially in the form of sulphuric anhydride, in the respective one of the chambers. A head introduces the first reagent, in the respective chamber, which head—includes a corresponding nozzle so calibrated to cause a predetermined load loss of said first reagent.

Abstract: An integrated process for the synthesis of urea and melamine, wherein: urea is synthesized with a stripping process in a high-pressure synthesis loop comprising a reactor, a stripper and a carbamate condenser, and the urea solution leaving said stripper is sent to a recovery section to produce a concentrated urea product and a recovered carbamate solution; at least part of said urea product is converted to melamine, and the off-gas from the synthesis of melamine are recycled to the urea synthesis by mixing with the gas phase from the stripper and with said recovered carbamate solution, thus forming a mixed flow which is then condensed in said carbamate condenser, and the condensate is eventually directed to the reactor.
