ANALYSIS ON STRIPPING EFFICIENCY DECREASE OF AMMONIA STRIPPER AND ITS IMPROVEMENT
The connection of stripping tube and the distributing tube in the ammonia stripper in urea plant didn't seal well, leading to the erosion corrosion on stripping tube end and side. The urea solution entered into the stripping tube directly from the corrosion clearance without formation of uniform liquid membrane, causing the stripping efficiency decreased. By increasing the pretightening force and the mode of the sealing gasket, the tripping efficiency was enhanced, therefore prolonging the life of the equipment, ensuring the safety and long term operation of the plant.
