  3. Abstract:
  4. As the membrane technology developed at the last 30 years, the relevant processes have been significantly developed. One of which is the chlor alkali technology. The development of membrane technology and its effect on Chlor-Alkali process is capable of evaluation in to two different fields, environmental and energy consumption. Some of environmental problems of mercury and diaphragm processes because of their technological development have been eliminated the energy consumption of these processes is significantly decreased especially in membrane and diaphragm processes. Recently investigation in the field of membrane cell is more focused on cell construction, depolarized cathodes, and fluid dynamics. At this work we focused on the historical development of membrane cell. Finally with regard to the past and present situation and using the published statistical data, predict the future of membrane cell technology. Which predicts the energy consumption at 2005 will be 2100(KWh/ton NaOH) and in 2010 will be 1400(KWh/ton NaOH)
