The issue of comprehensive energy utilization?
Thread Content
The chemical plant where I work has a unit for evaporating toluene. Toluene is fed into the tower at 50°C. I am considering changing the process so that the toluene is first cooled in a condenser at the top of the tower before being fed into the tower at its bubble point. I wonder how much energy can be saved by this approach; if 33 tons of toluene need to be evaporated per day, how much steam can be saved?
What was the original reaction heat of the poster, and what is it after the modification? What other heat exchange equipment is there in the intermediate process, and what is the heat transfer capacity? What pressure and temperature of steam is required? Without specific parameters, I really don’t know how to offer help. It is recommended that the original poster first consult the relevant professional forums for the thermal parameters required.
1. It is theoretically feasible, and thermal energy can be saved. 2. However, the capacity of the tower top condenser will decrease; it’s not clear whether this is compatible or not The equipment pipelines need to be modified accordingly. 3. The head of the pump needs to be increased, resulting in higher kinetic energy consumption. 4. A comprehensive consideration should be given.
Thank you for the reminder from the 3rd floor. Our factory is about to relocate, and all the equipment can be replaced with new ones; I just need the specific details! !
