Coking issue in the pre-hydrogenation feed heat exchanger?
Thread Content
This issue has been difficult to address; the heat exchange efficiency is poor, and both the load on the pre-hydrogenation furnace and the air cooling system increase as a result
Increase the flow rate on one hand, and reduce the temperature of the heating medium on the other hand

The possibility of coking is low; generally, the formation of ammonium salts is more likely. Pre-hydrogenation feed heat exchangers are usually equipped with a water injection system for washing away ammonium salts, and the amount of water injected is adjusted accordingly to remove ammonium salts from the feed heat exchangers and the areas surrounding the air coolers, thereby reducing pressure drops and improving heat exchange efficiency.
