      The Basket must be replaced ,no decision is required after its inspection.The basket life is not more than 20 years and by not replacing it will have to work for almost 30 years(15 Previous years and 15 further years with fresh catalyst).It is recommended , more Precisely,Required to arrange a new basket before it is Planned to replace the Convertor Catalyst

          dear

          Widodo Heru S,.

          Although it has been explained excellently by M.aslam, i would like to add following,

          The catalyst may last more than 20 year if operating temp and pressure remain consistent . and ammonia conversion remains in desired rang . As far basket is concerned ,its decision can be made after its inspection . if the condition is found good than one can continue with it

          Regards

            Dear;

            Nitriding produces a compact, brittle layer over the surface of steels generally in the range of 0.3-0.8 mm. The increasing rate of this layer slows down after an initial fast growth, since the layer itself act as a barrier to further penetration. On the internals, this layer does not cause any problem until it remains compact and does not crack.

            As you are operating for the last 18 years, it is expected that your catalyst is approaching end of life. With new catalyst, it is always recommended to change the basket also, as next opportunity will come after another long period for which basket may not be suitable.

                  dear friend
                  As mr farooq mentioned we have also a horizontal NH3 convertor that has been designed by MW kellog since 1995 without any problem and it has been working with the first catalyst up to now.
