WebbLiquefied Chlorine is one of the final products of the chlor-alkali process. At this point, most of the impurities have been removed and the Cl 2 is ready to be transported to the next process as a feed stock. Residual moisture in the stream will create corrosive compounds if the moisture exceeds the solubility of water in chlorine. WebbChlor-alkali products make everyday life safer, healthier and more convenient. ... In this process an electrical current passes through brine and splits apart the positive sodium and negative chloride ions to form molecular chlorine gas. The chlorine gas is dried, chilled and pressurized or converted to liquid for storage or shipping. The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), which are commodity chemicals required by industry. Thirty five million tons of chlorine … Visa mer The chloralkali process has been in use since the 19th century and is a primary industry in the United States, Western Europe, and Japan. It has become the principal source of chlorine during the 20th century. The … Visa mer See also Electrochlorination The initial overall reaction produces hydroxide and also hydrogen and chlorine gases: 2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2 Without a membrane, the OH ions produced at the … Visa mer The interests of chloralkali product manufacturers are represented at regional, national and international levels by associations such as Visa mer • Bommaraju, Tilak V.; Orosz, Paul J.; Sokol, Elizabeth A.(2007). "Brine Electrolysis." Electrochemistry Encyclopedia. Cleveland: Case Western Reserve University. Visa mer Three production methods are in use. While the mercury cell method produces chlorine-free sodium hydroxide, the use of several tonnes of mercury leads to serious environmental problems.
