Emergency power supply for ion-exchange membrane caustic soda plant
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 20:35. In the various processes related to ionized caustic soda production (using Asahi Kasei tanks in our factory), which equipment and instruments require emergency power supplies, UPS, or EPS? And how do they function in the event of a power outage? For example, the oil pressure pump of the electrolyzer extruder, pure water pumps, and so on. If anyone knows, I hope they will kindly share their knowledge. # hcbbs
Our emergency section equipment: electrolytic brine circulation pump, alkali solution circulation pump, brine feed pump, pure water pump, dechlorination vacuum pump, dechlorination fresh brine water pump, sodium hypochlorite feed pump, chlorine water pump； Alkali solution circulation pump for exhaust gas treatment, exhaust fan ； Fire pumps for utility systems. When the system trips, the backup power supply automatically comes online, but there is a 5 to 6 second delay, during which the operator needs to restart the pump. The DCS control system is equipped with a UPS power supply.
It needs to be discussed separately: 1. The equipment mentioned on the second floor, along with all the control systems, lighting systems, and security systems, require automatic backup power supplies that can be activated automatically. 2. Among them, all control systems should be equipped with UPS or EPS; this depends mainly on the investment capacity available. These are uninterruptible power supplies that ensure the continuous operation of the control systems. 3. Among them, the lighting and signaling facilities for evacuation should be equipped with emergency lights, such as those at exits and for indicating the direction to exits. This emergency light comes with its own battery.
The more detailed, the better. Please help me
