What are the bottlenecks in soda ash production during the summer? And what are the common methods used to solve it?

For the ammonia-alkali process, the main bottlenecks include the temperature for carbonization to produce alkali and the temperature for absorbing the off-gas.

Why do carbonization towers tend to form scabs more easily? Personally, I think this is due to the difference in temperature differences between the carbonization tower water tank and the mother liquor during heat exchange. In cold weather, the temperature of the cooling water is low, while the process temperature for carbonization remains essentially unchanged. So less water is used. In summer, the temperature of the cooling water is higher, resulting in greater water consumption. So it’s easier to stammer

In addition, there are bottlenecks such as the difficulty in lowering the furnace gas temperature and the kiln gas temperature.

In the production of caustic soda, the quality of the output depends on whether the heat generated during the reaction is removed promptly and in its entirety. Therefore, the biggest bottleneck in summer production is the poor cooling effect; after all, high ambient temperatures combined with high humidity make it difficult for the circulating water to cool down, which prevents the heat generated during the reaction from being removed effectively and in a timely manner. The heat that remains untreated then affects the progress of subsequent reactions. The main measure still lies in improving the heat transfer efficiency of the heat exchange equipment. For example, before the onset of summer, heat exchangers that may be prone to blockages should undergo treatments such as pickling to ensure that the heat exchange tubes and the shell side remain unobstructed ； Inspect the water distribution devices, nozzles, and associated water pumps in the cooling tower, and replace those that are faulty promptly. These can only play a role in the maintenance of the equipment.
