Stabilizer tower control
Thread Content
The control system of the stabilizer in the reforming unit maintains a top pressure of 0.8 Mpa. The bottom temperature is 185°C, while the top temperature is 52°C. After shutting down for maintenance and restarting, much less liquefied gas is produced than before. Let’s analyze what the reasons are
If there’s less liquefied gas, does that mean the separation effect has improved? This shows that your maintenance work is done very well. Add chicken legs at noon~
Check whether the temperature values are accurate, and also verify whether the feed rate is comparable to that before the shutdown
Have there been any changes in raw material properties, reaction depth, reaction process parameters, processing volume, reformate yield, etc.?
