# Commission Implementing Decision of 9 December 2013 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for the production of chlor-alkali (notified under document C(2013) 8589) (Text with EEA relevance) (2013/732/EU), Division: SCOPE

Extent: E+W+S+N.I.

These BAT conclusions cover certain industrial activities specified in Sections 4.2(a) and 4.2(c) of Annex I to Directive 2010/75/EU, namely the production of chlor-alkali chemicals (chlorine, hydrogen, potassium hydroxide and sodium hydroxide) by the electrolysis of brine.
In particular, these BAT conclusions cover the following processes and activities:
the storage of salt;
the preparation, purification and resaturation of brine;
the electrolysis of brine;
the concentration, purification, storage and handling of sodium/potassium hydroxide;
the cooling, drying, purification, compression, liquefaction, storage and handling of chlorine;
the cooling, purification, compression, storage and handling of hydrogen;
the conversion of mercury cell plants to membrane cell plants;
the decommissioning of mercury cell plants;
the remediation of chlor-alkali production sites.
These BAT conclusions do not address the following activities or processes:
the electrolysis of hydrochloric acid for the production of chlorine;
the electrolysis of brine for the production of sodium chlorate; this is covered by the BAT reference document on Large Volume Inorganic Chemicals – Solids and Others Industry (LVIC-S);
the electrolysis of molten salts for the production of alkali or alkaline earth metals and chlorine; this is covered by the BAT reference document on Non-ferrous Metals Industries (NFM);
the production of specialities such as alcoholates, dithionites and alkali metals by using alkali metal amalgam produced with the mercury cell technique;
the production of chlorine, hydrogen or sodium/potassium hydroxide by processes other than electrolysis.
These BAT conclusions do not address the following aspects of chlor-alkali production as they are covered by the BAT reference document on Common Waste Water and Waste Gas Treatment/Management Systems in the Chemical Sector (CWW);
the treatment of waste water in a downstream treatment plant;
environmental management systems;
noise emissions.
Other reference documents which are of relevance for the activities covered by these BAT conclusions are the following:
