Licenced Discharge Points (LDP)
The ChlorAlkali facility has three discharge points on EPA licence 20547. These are the hypo backing tower located at the sodium hypochlorite plant, the absorption tail tower located at the hydrochloric acid plant, and the emergency chlorine scrubber located at ChlorAlkali plant.
Hypo Backing Tower – LDP 1 (formerly LDP 3)
The backing tower is the end of the line emergency scrubber for the hypo and ferric plants. Its main duty is to remove the remainder of chlorine at the outlet of the hypo plant. It is designed to scrub the chlorine to less than 1ppm even during plant upset conditions.
Tail Tower – LDP 2 (formerly LDP 4)
The tail tower is used to dissolve any unabsorbed gases coming from the synthesis tower. By the time the gases reach atmosphere any remaining HCl fumes will have been dissolved in the demineralised water.
Tail Tower – LDP 3 (formerly LDP 7)
The emergency chlorine scrubber is installed to remove any remaining chlorine from the gas stream before being vented to atmosphere, or if a chlorine plant process upset occurs requiring absorption of all chlorine produced. The tower absorbs the gases vented to control the pressure in the chlorine distribution system.
