Storage of chlorine

The ozone hole over Antarctica results from the storage of chlorine-containing molecules on the surfaces of polar stratospheric clouds during the Antarctic winter followed by sudden photolysis and release in the spring. 

The bulk storage of chlorinated solvents is practised widely throughout the world and providing the correct... 

It is important to note that the philosophy of production, transportation, and storage of chlorine has changed drastically following the 9/11 incident Heightened security measures by the producers and the consumers have added significant costs to the industry. The consideration of relocation of consumers to nearby chlorine production facilities has received attention. The development of security regulations will impact the chlor-alkali industry in the future. 

C. Confined Storage. Another approach that would seem to provide inherent safety is the storage of chlorine in a fully confined system. The objectives in providing... 

New inorganic hypochlorite bleaching agents are unlikely to be developed. The relative economics and use patterns of hypochlorites for water treatment, cleaning, and disinfection are also unlikely to change. However, the use of hypochlorites as a safer alternative to transportation and storage of chlorine may increase. In the United States, this may also cause closer affiliation of hypochlorite production with chlorine sources. The competition with point-of-use electrolytic generators will also increase as these become cheaper and more prevalent. 

Many industrial uses of hypochlorite will also continue unchanged or increase, particularly for treatment of drinking water, cooling water, and wastewater. Hypochlorite avoids transport and storage of chlorine in populated areas, but it is more expensive and forms chlorate during storage. However, concerns about the formation of chlorinated organic by-products wiU continue to limit or decrease the use of hypochlorite for some other industrial purposes. 

L. J. Nuttal and A. B. LaConti, J.Power Sources, 2 191 (1977/78)] that the "electric to electric" (ETE) efficiency is less than 40%. Electrolysis of HCl could lead to an ETE efficiency of about 70%. Storage of chlorine should not present new technological problems in view of the wide production, transportation and use of chlorine.
