By the nature of the chemical reaction, chlorine, caustic soda and hydrogen are always manufactured in a fixed ratio: 1.1 tonne of caustic and 0.03 tonne of hydrogen per tonne of chlorine. This product combination is called an Electrochemical Unit or ECU. The average electricity consumption of a chlorine electrolysis plant is about 3.3 MWh per ECU.Web
