Apparatus and process for the preparation of ammonia and heavy water

Abstract From the Canadian patent

In order to replace the electricity required to drive the compressors of the apparatus, the nitrogen-producing means is supplied with a flow of a synthesis gas mixture from the synthesis circuit of the synthesizing plant. This gas mixture is burned with compressed air to form a mixture of water vapor and nitrogen. The water vapor is then condensed in a condensor and separated out for entry into an exchange tower of the monothermal isotope exchanger. The separated nitrogen is supplied together with hydrogen to form the synthesis gas mixture for the synthesizing plant. In addition a steam circuit is connected with the condensor and has a steam turbine which produces work to drive the …
