How to handle a disruption in the heat source for the heat exchanger?
What do you use as the heat source for analyzing the tower?
In the event of an interruption, first, change the crude gasoline to the substandard stream and enable circulation in the absorption and stabilization towers. Second is normal operation, with the deethanized gas being discharged at the top of the stabilizer
Reply to 2# zhxsh6666: Use steam
1. If the control valve fails, contact the instrumentation team for handling and switch to bypass operation. 2. If there is a short-term steam interruption, the reaction rate decreases, which reduces the amount of stable gasoline fed into the absorption tower; if the pressure in the stabilizer is high, it can be controlled through the non-condensable gas control valve. 3. In the event of a prolonged interruption, the crude gasoline becomes unqualified; the outlet of the compressor is directed to the flare, or the compressor is shut down for handling, while the absorption and stabilization process is switched to a three-tank cycle ； If that doesn’t work, stop working.
