FIELD: production of non-concentrated nitric acid. SUBSTANCE: method involves obtaining nitrogenoxides; absorbing nitrogen oxides; heating gas discharged upon absorption of gas; recovering waste gas energy in gas turbine unit; feeding gas mixture from gas turbine into cleaning reactor, where oxides are recovered in the presence of ammonia. Number of failures per year is five (in unit operating under pressure of 0.716 mPa). EFFECT: increased efficiency of method. 1 tbl
