| titleOfInvention | Process and apparatus for preparation of nitric acid |
| abstract | The invention relates to a method for producing nitric acid from ammonia and oxygen-containing gas applying the single pressure or dual pressure process, characterized in that during the start-up and/or shut-down of the nitric acid plant, a process gas is flowing through a process gas cooler (3) and/or a feedwater preheater (2), which process gas is heated in the process gas cooler (3) and/or in the feedwater preheater (2) and is conveyed through at least one heat exchanger (5, 4) located downstream of the process gas cooler (3) and/or the feedwater preheater (2) in order to transfer thermal energy from the heated process gas to a residual gas. The invention further relates to a device for carrying out the method. By means of said methods and/or devices, a freezing of the residual gas turbine can effectively be prevented. |
