Lead oxide chloride, mill

The majority of the chlorine produced is used internally within the chemical industry for the manufacture of polyvinyl chloride, chlorinated hydrocarbons, propylene oxide, etc, (Table 3.1), Hence, it is common to find chlor-alkali plants as part of very large, integrated chemical complexes and the capacity of such plants may be 0,5 x 10 tons Ci2/yean On the other hand, concern about the transport and storage of liquid chlorine has led to a different trend towards smaller plants sited close to the user This is particularly attractive when there is an almost balanced requirement for both chlorine and sodium hydroxide, e.g. in pulp and paper mills (Table 3,1). A typical plant in this application may have a capacity of 10 ions Cl2/year, On an even smaller scale, the same concerns lead to a need for plants, for example, to provide Cl to prevent biological growth on...
