Narrative:

Entered icing conditions at 13000 ft. Right engine intake heat was deferred and placarded. We selected right intake heat on and it worked normally. Exited icing conditions as soon as possible. No problems on returning to msp departure point. We were about 25 NM from airport when we turned around.
