What is the purpose of the process for controlling the liquid level in the [chlorine scrubber]? What level is reasonable for control?
The purpose of controlling the liquid level in the chlorine scrubber tower is to prevent the liquid level from being too low, which could cause the pump to draw in chlorine, and to avoid the liquid level from being too high, as this would block the chlorine inlet and lead to fluctuations in the chlorine flow in the main pipeline. Based on the above objectives, and in accordance with the design of the scrubber tower, it is reasonable to control the corresponding positions
The high-temperature, wet chlorine gas produced by electrolysis contains a large amount of water; if the liquid level is not controlled, it can flood the gas inlet as mentioned on the second floor, ultimately affecting the chlorine-hydrogen pressure difference and disrupting production. In severe cases, this can lead to the shutdown of the electrolyzer via interlock protection. The chlorine scrubber serves to cool, remove water, and desalt the gas. The liquid level control range is determined such that it does not affect the pump’s operation nor cause the gas inlet to be submerged; to ensure stable production, the liquid level is generally set at a mid-value.
