| titleOfInvention | A kind of methenamine recovery process |
| abstract | The invention discloses a kind of methenamine recovery process, it is characterized in that, comprise the following steps: step 1: rectifying column technique centrifuge mother liquor is out separated by the continuous chromatography piece-rate system that is filled with ammonium type strong acidic ion resin, obtain methenamine solution and ammonium chloride solution; Step 2: adopt counter-infiltration system to concentrate to obtain methenamine reverse osmosis concentrated liquid methenamine solution, the methenamine reverse osmosis concentrated liquid obtaining is returned to Crystallization Procedure. Methenamine recovery process of the present invention, separates centrifuge mother liquor and reverse osmosis concentration by continuous chromatography successively, has the advantages such as technique is simple, good separating effect, and the methenamine rate of recovery is high, cost recovery is low. |
