After the general maintenance of one of our FCCU’s, we do not operate it again due to the drop in the fuel market (covid-19). To preserve the unit, we are inerting the gas recovery area and the main tower with N2. What other precautions do we need to take (compressor, blower, pumps, ovens, etc.)?
There is a long list of items that will need to be addressed. The main question should be if you are going to bring it back on line in the fairly near future. A big issue are your pump seals including dry gas seals on compressors. I would revise the shut down and start up procedures to safely document everything that you are doing to preserve the unit.
