What are the design flaws of the radial cold-jet ammonia synthesis tower?
(1) The cold shock gas only serves to lower the temperature; it does not participate in the synthesis reaction, and at the same time it dilutes the ammonia concentration, thereby affecting the ammonia production rate to some extent. (2) The production intensity is low, and the volume utilization factor is not optimal. (3) Internal inspections are difficult; it is necessary to cut open the welded gasketing and lift the large cover of the synthesis tower, which involves a lot of work. Leaks may also occur during reinstallation and welding. (4) The catalyst is difficult to replace.
