【Abstract】 Technical renovation is carried out of 2 500/3 250 absorption towers and the 4 000 regeneration tower in the carbon dioxide removal system of the Benfield Process with the help of the combined technology of structured packings, random packings and new type of liquid distributors. This is the first retrofit of the towers in the carbon dioxide removal system in a large imported 1 000 t/d ammonia unit in China. An evaluation of the technical renovation shows that expected results are obtained through retrofit, conditions are provided for further tapping the potentials of the unit, and an active role is played in the optimization of the process indicators of the unit in operation.更多还原
