Issues with instrument reserves and density.

2022-08-03View Original

Thread Content

In catalytic unit reactors, regeneration is generally based on reserve and density. During operation, there are occasional issues with inaccurate density readings; there is positive and negative pressure, as well as reverse airflow. So, what should be done if the density value is incorrect? What are the steps for treating with reverse blowing air? Is it necessary to turn off the positive and negative pressures of the transmitter, or should the wall valves be turned off?
