Title (EN) METHOD AND FACILITY FOR PRODUCING A LIQUID FERTILISER FROM AIR LOADED WITH AMMONIA FROM ANIMAL URINE
(FR) PROCEDE ET INSTALLATION DE PRODUCTION D'UN ENGRAIS LIQUIDE A PARTIR D'AIR CHARGE EN AMMONIAC PROVENANT D'URINE D'ANIMAUX
Abstract:
(EN) The invention relates to a method for producing a fertiliser from air from urine. Said method comprises the following steps: a) an acid solution is circulated through a conduit (1), and an air flow loaded with ammonia is circulated counter-currently in such a way as to at least partially extract the ammonia contained in the air due to the passage of urine over said air flow, one end (11) of said conduit (1) communicating with a storage tank (3) containing said aqueous acid solution and receiving the ammonium salt formed; b) the pH of the liquid in the tank (3) is permanently maintained at a nominal value between two value limits ph1 and pH2 by acid addition; c) once a high level of said tank (3) is reached, the introduction of urine is interrupted in such a way as to circulate a flow that is more and more depleted in ammonia and the circulation of said liquid is continued but without maintaining the pH; d) the circulation of said liquid is interrupted as soon as it reaches a nominal value pH3; and e) said liquid is extracted.
(FR) L'invention se rapporte notamment à un procédé de production d'un engrais à partir d'air provenant d'urine. Il comprend les étapes suivantes : a) à travers une conduite (1), on fait circuler une solution d'acide et à, contre-courant, un flux d'air chargé en ammoniac, de manière à extraire au moins partiellement l'ammoniac contenu dans l'air provenant du passage d'urine sur ce flux d'air, une extrémité (11) de ladite conduite (1) communiquant avec un réservoir de stockage (3) dans lequel est contenue la dite solution aqueuse d'acide et dans lequel est reçu le sel d'ammonium formé; b) on maintient en permanence le pH du liquide du réservoir (3) à une valeur de consigne comprise entre deux bornes de valeurs ph1 et pH2 par ajout d'acide; c) une fois un niveau haut dudit réservoir (3) atteint, on interrompt l'introduction d'urine de manière à faire circuler un flux de plus en plus appauvri en ammoniac et on continue, à faire circuler ledit liquide, mais sans procéder à un maintien du pH; d) on interrompt la circulation dudit liquide dès lors que ce dernier a atteint une valeur de consigne pH3, et e) on extrait ledit liquide.
