Abstract
A method is disclosed for reusing the processing condensates in a combined plant for the production of ammonia and urea. The condensates are combined into a single stream, filtered to remove the solid substances in suspension, if any, and fed to a boiler for the production of steam while exploiting the sensible heat. Pollution of sewage waters is prevented while obtaining a considerable economy in the running costs.
