  • Patent number: 6825346
    Abstract: A process for producing melamine crystals at high pureness is distinguished by the fact that it comprises a crystallisation step of a flow comprising substantially pure melt melamine by cooling with liquid ammonia and a thickening step of the resulting suspension of melamine crystals in liquid ammonia by separation of a portion of the liquid ammonia present in said suspension, whereby the liquid ammonia separated in said thickening step is reused as coolant in the crystallisation step.

  • Patent number: 6730278
    Abstract: In a process for the production of urea, substantially pure ammonia and carbon dioxide are reacted in a reaction space (1) from which comes out a reaction mixture subjected to stripping (2) to obtain a partially purified mixture sent to a urea recovery section (3, 4, 7, 8). From the recovery section (3, 4, 7, 8) it is obtained a dilute carbamate solution, which is subjected to stripping (9) with recycling of vapors to the reaction space (1) after condensation (6). This process achieves high conversion yield with reduced energy consumption and low implementation costs.

  • Patent number: 6702992
    Abstract: A method for the modernization of a plant for urea production of the type comprising a reactor (2) for urea synthesis, a stripping unit (3) with carbon dioxide and at least one vertical condensation unit (4) of the film type, foresees the provision of means (36) for feeding a major portion of a flow comprising ammonia and carbon dioxide in vapor phase leaving the stripping unit (3) to the condensation unit (4) and the provision in said condensation unit (4) of means (37) for subjecting to substantially total condensation such major portion of the flow comprising ammonia and carbon dioxide in vapour phase, obtaining a flow comprising urea and carbamate in aqueous solution, then fed to the reactor (2) for urea synthesis. Thanks to the present method of modernisation, the efficiency of the condensation unit (4) is remarkably improved, thus permitting an increase of its capacity.
