How to reduce fluctuations? This post was last edited by yfq4308 on 2009-3-3 11:17 ]
⒈According to the changes in the feed amount, the tower bottom temperature can be adjusted in time, and the tower pressure, reflux volume, and external rejection volume can be stably cut into the tower. ⒉Make the adjustment smaller.
When the outlet temperature of the heating furnace is stable and the feed amount is stable, the low temperature of the coke tower is above 340 and the tower wall temperature is above 280 and the system pressure is stable. Is it better to change the tower?
What’s a good way to solve the problem of high summer temperatures in lean-liquid water coolers?
What kind of tower is it? The operating steps should be different for different towers.
Preheating is in place more than half an hour in advance, and the fractionation system is relatively stable.
