Author has introduced the process flow and main equipment for ammonia recovery from middle pressure stripper condensate;has analyzed the reasons of the problems existing in commission and production about gasification of medium of pressurizing pump,leakage of head of condensate heater,tray falling off of middle pressure stripper etc.;has proposed the reforming measures of these aspects of adding venting valve on the case of pressurizing pump,silver coating integrally at gasket surface of the head of condensate heater,adding anti-rotating piece etc.;result indicates that the condensate can be used as demineralized water after technical reformation,the synthetic ammonia production can be increased by 2 t/d.
