What will happen to the operating system during normal operation if there is a malfunction with the solenoid valve?
The program proceeds, and the system will issue an alarm. Depending on the importance of the valve controlled by the solenoid valve, this can lead to failure to meet process specifications, venting, and safety accidents
In the event of a sudden power outage, the operating equipment of the system will stop working, the control system will no longer output any signals, the solenoid valves will return to their default position due to the power loss, and all programmable valves will close as a result of the action of the accumulators. Therefore, in the event of a power outage: immediately sound the stop signal for the compression unit and inform them by phone that the decarburization process has been halted. After contacting the compression team, reach out to relevant teams and personnel such as those in charge of crude alcohol production, gas generation, shift conversion, and scheduling, and ask an electrician to come and check the cause of the fault. Record the pressure and conditions of each tower; after troubleshooting, contact the dispatch to start up the operation.

When the solenoid valve is damaged, the valve cannot open and close properly, which triggers a system alarm. The pressure in the pressure equalization towers becomes abnormal, and the pressure difference between them decreases; in severe cases, the pressures of several towers become almost equal. The venting pressure rises to extremely high levels, posing a serious threat to safe production. There are also sudden changes in the sound of venting, so it is necessary to identify the faulty tower as soon as possible and take action to address it
