Operation of C4/C5 separation tower

You can look for some operating procedure materials; it is recommended to ask questions and discuss

The parameter values you provided indicate poor separation efficiency in the stabilizer tower, resulting in substandard products at both the top and bottom of the tower. Solution: 1. Check whether the stabilizer is operating under overload; if so, reduce the feed rate to the stabilizer. 2. Check whether the pressure drop in the stabilizer column is greater than 36 KPA; if it is, it indicates that the liquid layer remains on the tray, and the gas-liquid separation function is not working properly. Appropriately reduce the processing volume and the reflux rate, and increase the tower pressure; there is no need to lower the temperature at the bottom of the tower to 140 degrees for now. Once the tower pressure drops below 36 KPA, gradually increase the feed rate and adjust the parameters back to normal levels. The area above the feed inlet belongs to the distillation section, and adjustments are made accordingly based on the temperature changes at various points in the upper part of the tower.
