15 - PROCESS FOR THE CONTINUOUS PRODUCTION OF HYDROXYLAMMONIUM A13STRA PROCESS AND EQUIPMENT FOR THE CONTINUOUS PRODUCTION OF HYDROXYL AMMONIUM BY REDUCTION OF NITRATE IONS OR NITROGEN OXIDES WITH HYDROGEN 5 IN THE PRESENCE OF A CATALYST WHEREBY THE HYDROXYL AMMONIUM IS PRODUCED IN 2 OR MORE PARALLEL PLACED HYDROXYL AMMONIUM PRODUCTION UNITS WHICH PROCESS IS OPTIONALLY PART OF A PROCESS FOR THE PRODUCTION OF CYCLOHEXANONE OXIME IN WHICH AN INORGANIC PROCESS LIQUID IS CYCLED FROM A HYDROXYL AMMONIUM SYNTHESIS ZONE (A) TO A CYCLOHEXANONE OXIME SYNTHESIS ZONE (B) AND BACK TO THE HYDROXYL AMMONIUM 1 0 SYNTHESIS ZONE FOR EXAMPLE THROUGH AN EXTRACTION ZONE (G) AND A NITRIC ACID PRODUCTION ZONE (D), IN WHICH HYDROXYRI AMMONIUM SYNTHESIS ZONE HYDROXYL AMMONIUM IS FORMED BY REDUCTION OF NITRATE IONS OR NITROGEN OXIDES WITH HYDROGEN IN THE PRESENCE OF A CATALYST, AND IN WHICH CYCLOHEXANONE OXIME SYNTHESIS ZONE HYDROXYL AMMONIUM IS REACTED WITH CYCLOHEXANONE TO FORM CYCLOHEXANONE OXIME.
