Factors affecting the C3 content in catalytic cracking dry gas
Thread Content
How do the feed temperature of the desorption tower and the temperature of the desorption tower reboiler affect the C3 content in the dry gas? Is there any inevitable connection? ? Beginners can’t understand it. .
The separation efficiency of the separation tower directly affects the absorption efficiency, and the C3 content is influenced by the absorption efficiency. One of the factors affecting separation efficiency is temperature; therefore, the feed temperature and the temperature of the reboiler at the bottom of the tower affect the C3 content in the absorption tower by influencing its separation efficiency. To put it another way: if the temperature of the distillation tower is too high, excessive distillation occurs, which results in poor absorption and ultimately leads to a decrease in the C3 content.
