Top water cooler of the thermal regeneration tower
Thread Content
How should the top water cooler of the thermal regenerator be put into use during the initial startup phase of low-temperature methanol washing, and what are the precautions to take?
Put into use in advance to establish a water circulation system for exhaust and water intake.
Could you explain it in more detail? Because I’m new to this industry and don’t know much about it yet\ud83d\ude4f
1. Open the exhaust valve at the top of the cooler. 2. Slightly open the water inlet valve. 3. Once exhaust is complete, allow water to flow continuously and then close the exhaust valve. 4. After fully opening the water inlet valve, partially open the water outlet valve. 5. After the regeneration tower is in operation, adjust the opening degree of the water outlet valve according to process requirements
Ensure thorough exhaust; first add cold water, then hot air
Just install a circulating water heat exchanger; it can be put into use following the standard procedures for such heat exchangers.
When putting it into use, add water first to ensure complete exhaust of air, and then add hot gas； When shutting it down, turn off the hot gas first and then the water. The seal might leak when it’s shut down; tightening it again should resolve the issue
First, use the water side; exhaust air from the water side to the water outlet and open the return water valve, then use the heat side.
The water cooler of the thermal regeneration tower was put into operation during the preparation phase before startup; after the circulation water pump was started, the various circulation water heat exchangers were brought online one after another. Ignore him. Once the methanol cycle is established and steam is supplied to the thermal regeneration tower, the methanol vapor will gradually condense.
