What are the main factors affecting the cooling efficiency of the water cooler in methanol synthesis? Answer: The reduced cooling effect of water cooling may be due to the following reasons: 1) The amount of water has significantly decreased, which affects its cooling capacity. The cooling water inlet valve can be opened wider and the cooling water pressure can be increased to increase the amount of cooling water. 2) The accumulation of scale and sediment on the wall of the water layer in the water cooler increases, which affects heat transfer and the removal of heat, thereby impacting the cooling effect. 3) The water quality is relatively poor, and the water may contain impurities such as plastic sheets. These impurities have a significant impact on the cooling efficiency of the water cooler, especially in shell-and-tube heat exchangers. They accumulate on the inlet plates of the cooler, blocking the pores and preventing smooth flow of water, thereby affecting the cooling effect. In such cases, in addition to improving water treatment and purification, two parallel filters can be installed before the water enters the cooler to remove these impurities. 4) Paraffin is produced during methanol synthesis, and this paraffin adheres to the inner walls of the condenser tubes; over time, this has an increasingly negative impact. If wax accumulation is severe and affects production, steam purging or thermal cooking can be employed to remove it.
The main issues are: 1) The water volume has decreased significantly, which affects its cooling efficiency. The cooling water inlet valve can be opened wider and the cooling water pressure can be increased to increase the amount of cooling water. 2) The scaling and silt accumulation on the wall of the water layer in the water cooler increase, which affects heat transfer and the removal of heat, thereby impacting the cooling efficiency. 3) The water quality is relatively poor, and the water may contain impurities such as plastic sheets. These impurities have a significant impact on the cooling efficiency of the water cooler, especially in shell-and-tube heat exchangers. They accumulate on the inlet plates of the cooler, blocking the pores and preventing smooth flow of water, which in turn affects the cooling effect.
