  • History of the Chlor-Alkali Industry
    2 History of the Chlor-Alkali Industry During the last half of the 19th century, chlorine, used almost exclusively in the textile and paper industry, was made [1] by reacting manganese dioxide with hydrochloric acid 100–110◦C MnO2 + 4HCl −−−−−−→ MnCl2 + Cl2 + 2H2O (1) Recycling of manganese improved the overall process economics, and the process became known as the Weldon process [2]. In the 1860s, the Deacon process, which generated chlorine by direct catalytic oxidation of hydrochloric acid with air according to Eq. (2) was developed [3]. ◦ 450–460 C;CuCl2 cat. 4HCl + O2(air) −−−−−−−−−−−−−−→ 2Cl2 + 2H2O(2) The HCl required for reactions (1) and (2) was available from the manufacture of soda ash by the LeBlanc process [4,5]. H2SO4 + 2NaCl → Na2SO4 + 2HCl (3) Na2SO4 + CaCO3 + 2C → Na2CO3 + CaS + 2CO2 (4) Utilization of HCl from reaction (3) eliminated the major water and air pollution problems of the LeBlanc process and allowed the generation of chlorine. By 1900, the Weldon and Deacon processes generated enough chlorine for the production of about 150,000 tons per year of bleaching powder in England alone [6]. An important discovery during this period was the fact that steel is immune to attack by dry chlorine [7]. This permitted the first commercial production and distribu- tion of dry liquid chlorine by Badische Anilin-und-Soda Fabrik (BASF) of Germany in 1888 [8,9]. This technology, using H2SO4 for drying followed by compression of the gas and condensation by cooling, is much the same as is currently practiced. 17 “chap02” — 2005/5/2 — 09Brie:49 — page 17 — #1 18 CHAPTER 2 In the latter part of the 19th century, the Solvay process for caustic soda began to replace the LeBlanc process.

    EUROPEAN COMMISSION Integrated Pollution Prevention and Control (IPPC) Reference Document on Best Available Techniques in the Chlor-Alkali Manufacturing industry December 2001 Executive summary EXECUTIVE SUMMARY This reference document on best available techniques in the chlor-alkali industry reflects an information exchange carried out according to Article 16(2) of Council Directive 96/61/EC. The document has to be seen in the light of the preface which describes the objectives of the document and its use. The chlor-alkali industry The chlor-alkali industry is the industry that produces chlorine (Cl2) and alkali, sodium hydroxide (NaOH) or potassium hydroxide (KOH), by electrolysis of a salt solution. The main technologies applied for chlor-alkali production are mercury, diaphragm and membrane cell electrolysis, mainly using sodium chloride (NaCl) as feed or to a lesser extent using potassium chloride (KCl) for the production of potassium hydroxide. The diaphragm cell process (Griesheim cell, 1885) and the mercury cell process (Castner- Kellner cell, 1892) were both introduced in the late 1800s. The membrane cell process was developed much more recently (1970). Each of these processes represents a different method of keeping the chlorine produced at the anode separate from the caustic soda and hydrogen produced, directly or indirectly, at the cathode. Currently, 95% of world chlorine production is obtained by the chlor-alkali process. The geographic distribution of chlor-alkali processes world-wide differs appreciably (production capacity of chlorine): - western Europe, predominance of mercury cell process (June 2000): 55% - United States, predominance of diaphragm cell process: 75% - Japan, predominance of membrane cell process: >90% The remaining chlorine production capacity in western Europe consists of (June 2000) diaphragm cell process 22%, membrane cell process 20% and other processes 3%.

However, only limited studies have investigated the optimum electrolysis parameters and the bactericidal effect of acidic electrolyzed water (AcEW) and alkaline electrolyzed water (AlEW). Here, the Box–Behnken experimental design was used to identify the optimum parameters. The tests were conducted with different types of electrodes, electrical voltages, electrolysis times, and NaCl concentrations. There were no obvious differences observed in the physico-chemical properties of EW when different electrodes were used. However, stainless steel was chosen as it meets most of the selection criteria.

  • The European Chlor-Alkali Industry: an Electricity Intensive Sector Exposed to Carbon Leakage
    Brussels, December 2010 The European Chlor-Alkali industry: an electricity intensive sector exposed to carbon leakage The revised EU ETS (Emission Trading Scheme) Directive 2009/29/EC will have financial consequences for all energy-intensive industries. The chlor-alkali industry is in particular exposed to a significant risk of carbon leakage due to CO 2 costs passed through in the electricity prices. The Directive recognises the need to avoid carbon leakage whilst at the same time fulfilling the climate change objective of reducing CO 2 emissions and, consequently, it allows Member States to adopt financial measures to compensate energy-intensive sectors for the additional costs of carbon passed through in electricity prices. This document aims at explaining why and how the chlor-alkali industry is highly impacted by the EU Emission Trading Scheme. 1. The chlor-alkali industry 1.1. The importance of the European chlor-alkali industry Chlorine and caustic soda are basic building blocks for thousands of useful substances and products. The chlor-alkali industry underpins about 55% of the European chemicals and pharmaceuticals industry which realised in 2009 a turnover of almost 660 billion euro. About 20 million tonnes of chlorine, caustic soda and hydrogen are produced each year at 76 manufacturing sites in 22 European countries. The chlor-alkali sector employs about 39,000 people. About two thirds of European chlorine production is used in engineering materials – polymers, resins and elastomers. The largest single end use (35%) is PVC plastic for primarily the construction, automotive, electronic and electrical industries. The manufacturing processes of many chemicals, plastics and medicines use chlorine, although the end product is chlorine-free, such as the plastics polyurethane and polycarbonate which have increasing numbers of applications.

    PROCESS ECONOMICS PROGRAM SRI INTERNATIONAL Menlo Park, California 94025 Abstract Proceee Economic Program Report No. 61 D CHLORINE (June 1992) Chloralkali producers around the world - in the major industrialized countries in particular - are pondering the balance between sagging demand for chlorine and strong demand for caustic soda. The former is caused by increasing environmental pressure in the following major sectors: l Dioxin generated during pulp bleaching with chlorine has forced the pulp and paper indus- try to switch from chemical bleaching to chemi-thermal mechanical bleaching, replacing chlorine with hydrogen peroxide. l Serious depletion of ozone layers has caused the major industrialized countries to totally phase out CFC production by 1995-l 996,4 to 5 years ahead of the deadline set by the 1990 internationally approved Montreal Protocol. l Laws in Western Europe have been proposed to restrict the use of PVC for food and non- food packaging. This report, a supplement to PEP Report 61 C issued in December 1962, presents a compre- hensive review of technology and economics for the production of primary chlorine by electrolysis of brine in the membrane cell, diaphragm cell, or mercury cell processes, and production of secondary chlorine by catalytic oxidation as well as electrolysis of HCI. Also presented are preliminary eco- nomicsfor process conversion and retrofit from either mercury cells or diaphragm cells to membrane cells.
