True or False: The factors that affect the operation of a distillation tower include changes in the tower’s pressure and temperature, the properties of the feed material, the amount of feed and reflux entering the tower, as well as the amount of product extracted and the volume of gas produced. （ ）right
Correct,√~~~~~~~~~~~
Factors affecting the operation of a fractional distillation tower include changes in the tower’s pressure and temperature, the properties of the feed material, the amount of feed and reflux entering the tower, as well as the amount of product withdrawn and the volume of vapor. (V)
Top pressure, Bottom pressure, Feed rate, Stripping steam, Return flow, Extraction rate
Changes in oil and gas volume in the coke tower (minor and major purging in the old tower, preheating in the new tower)
