Reasons for the large fluctuations in Chang San’s performance
Thread Content
Chang San experiences significant fluctuations; overall adjustments in daily operations are not substantial. What are the reasons for this?
How many side streams at atmospheric pressure? Three or four? If it is the lowest side line, consider increasing the reflux slightly, or reducing the temperature at the outlet of the heating furnace within a certain range. The fluctuations are quite large; one reason for this is the entrainment of mist, and in that case increasing the reflux rate slightly could be considered. Another reason is the poor gas-liquid equilibrium resulting from an excessively high vaporization rate in the heating furnace!
:Lol, we’re just feeding wax oil in here; nothing is being controlled
