What to do if the computer in the diol synthesis tower freezes?
The computer freezes, but the control system continues to operate normally (this is a requirement of the control system’s design); it’s just that you cannot input signals. Solution: (1) Have specialized instrument maintenance personnel handle it ； (2) Restart the computer ； (3) Pay attention to the conditions at the site, especially the temperatures of the methanol separator and the synthesis tower.
In modern system controls, there is usually a backup computer available that allows you to manage and control the system in case the main control computer freezes or crashes. With older systems, one can only wait for the computer to restart before proceeding with operations; the system generally continues to operate as usual. If a crash does occur, there isn’t much that can be done about it
