The desalinated water flowing through the water cooler interacts with low-pressure steam
Thread Content
Our factory has two water coolers. The first one is used for heat exchange with desalinated water; what is the purpose of using low-pressure steam? The temperature coming out of the heat exchanger is very high – how can low-pressure steam be used to reduce this temperature?
It would be best to have a diagram; please explain the location of this heat exchanger, as well as the process conditions such as inlet and outlet pressures and temperatures
Desalted water is used as the heat transfer medium to prevent scaling in the water cooler and thus maintain effective heat transfer, while low-pressure steam is primarily used for wax melting.
The low-pressure steam pipe should be a backup, so that steam can be used for heating when the temperature is too low.
Normally, there is only desalinated water, used to cool the process gas, as well as a tank for heating the desalinated water to remove oxygen. The steam pipe is used for wax removal after shutdown.
Desalinated water; steam is used for heating during shutdown – water is poured in and then heated with steam through boiling. This is my own idea; just for reference
Desalinated water is used as the cooling medium, while steam is employed during shutdown to remove wax buildup; this is because wax accumulation in the water coolers can affect heat exchange efficiency
The answer is upstairs; low-pressure steam is used for boiling and blowing wax
I have the feeling that what the original poster is talking about is just a deaerator
