The pressure difference across the heat exchanger increases
Thread Content
The pressure difference across the inlet and outlet of the hydrogenation heat exchangers E-102/E-103 increased suddenly. What causes it, and what are the solutions?
It might form ammonium salts! Redirect the water flow to the heat exchanger!
Increase the water injection volume to raise the outlet temperature of the reaction products from the heat exchanger above 220°C, and check whether the chloride ion content in the raw material exceeds the specified limit
