Issues related to the normal operation of styrene plants

In styrene plants, principles and steps for operating the ethylbenzene/styrene separation tower at reduced load；
Reduce the feed amount by lowering the draw rates from the top reflux tank and the bottom of the tower, respectively. Of course, for even better results, one can reduce the reflux rate and use less steam to save energy.
Additional note: Take a look, okay? Principle: The tower bottom must be qualified； Steps: First reduce the feed, then reduce the steam
1. Try to avoid changes in the reflux flow； 2. Reduce feed rate ； 3. Reduce steam ； 4. Reduce recovery.
1. Reduce load. 2. Reduce extraction rate. 3. Adjust the amount of reflux based on the liquid level in the reflux tank. 4. Adjust the amount of steam based on the liquid level at the bottom of the tower. 5. The prerequisite is to ensure that the styrene at the bottom of the tower meets the required standards
