A fundamental understanding of porous diaphragm membrane utilized by Dow Chemical Company in the production of chlorine gas and caustic soda, is integral to optimizing its performance. Several factors have been identified as integral components in this effort to optimize the chlorine cell diaphragm. Among these components are the diaphragm's porosity, pore size, thickness and tortuosity. Several methods have been utilized in an effort to determine not only the desired values of each of these variables but also to develop ways of achieving these desired values. Because not all of these variables can be measured directly, other methods of collecting the necessary data have been determined in an effort facilitate the rapid optimization of the porous diaphragm membrane. The primary focus of this thesis is the discussion of the importance of each of these variables to the overall performance of the diaphragm as well as the method of measuring and optimizing each variable. Future efforts in the development of a non-asbestos porous membrane will also be discussed.
