For current information see Sodium hydroxide and Chloralkali process.

The Chloralkali process is an industrial process for the electrolytic production of sodium hydroxide and chlorine.

Because a whole industry-most of the chemical industry-is founded upon a single reaction: the Chloralkali process- turning salt water into covalent chlorine.

The most common chloralkali process involves the electrolysis of aqueous sodium chloride (a brine) in a membrane cell.

The Weldon process was first replaced by the Deacon process and later by the Chloralkali process.

There are no longer any operating chlor-alkali facilities in Ontario.

It began as a manufacturer of chlor-alkali and petrochemical commodities and feedstocks.

The second amendment concerns mercury-cell chlor-alkali plants.

Mercury cell chlor-alkali production is a significant user of mercury and a source of mercury releases to the environment.

To support the Workshop on Reducing Mercury Releases from Chlor-Alkali Production.

In 1972, the federal government issued a regulation under the Fisheries Act to limit the discharge of mercury in effluents from mercury-cell chlor-alkali plants.

Today, membrane cell systems are one of the most promising and fast-developing techniques for producing Chlor-alkali and it will undoubtedly replace other techniques.

Instead, most mercury supplies come from recycling of mercury products such as thermostats, as well as decommissioned mercury-cell chlor-alkali plants.

Orica's Botany site was contaminated during the operation of a mercury-cell chlor-alkali plant by Orica and its predecessors between 1944 and 2002.

The Environment Canada Reference Method described in this report determines the rate of mercury emissions from mercury cell chlor-alkali plants.

Currently there are three integrated chemical plants (titanium dioxide pigment, chlor-alkali and air separation) and a silicon smelter in the estate, occupying 215ha.

The proposal includes parallel provisions on safe storage of the excess mercury which will mainly be coming from decommissioned mercury-cell chlor-alkali plants, to prevent its re-sale.

Tosoh Corporation is divided into 13 business divisions that are organized in five groups: Petrochemical, Chlor-alkali, Speciality and Engineering.

Shanghai Chlor-Alkali Chemical Co., Ltd.

The industry responsible for this contamination was the Dow Chemical Chlor-Alkali Plant in Sarnia, Ontario.

Partnership areas in which countries have expressed interest include coal fired power generation, artisanal gold mining, mercury inventories, mercury-containing products and the mercury cell chlor-alkali sector.

EuroChlor, the European Chlor-alkali producers association, has set a target for Western European installations to reduce overall emissions of mercury by 2007.

Similarly, while code 58 (chlor-alkali) ranks as 13th under the procedure outlined in the pre-workshop background information, it ranks as 12th by the alternative procedure involving weighting.

Commission decision on aid for Bitterfeld Chlor-Alkali GmbH (BCA), Saxony-Anhalt.

SP Chemicals, a Singapore-based company is one of the largest ion-membrane chlor-alkali producer and aniline producer in the PRC.

In Canada, mercury releases from human sources have declined since the 1970s due to pollution control and other measures, particularly in the base metal smelting and mercury-cell chlor-alkali sectors.

The company specialized for isocyanates (MDI, TDI), PVC and chlor-alkali (vinyl) businesses.

SunBelt Chlor-Alkali earnings are expected to be lower compared with second-quarter 2007 and first-quarter 2008 results, due to low incremental chlorine demand outweighing benefits from higher caustic pricing.

INTRODUCTION In December 2002 the Commission presented a report to the Council concerning mercury from the chlor-alkali industry1.

Bitterfeld Chlor-Alkali GmbH (BCA), formerly ‘Chlore IV’, is the product of the setting-up of two companies.
