# 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 1: Cell technique

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

BAT 1: BAT for the production of chlor-alkali is to use one or a combination of the techniques given below. The mercury cell technique cannot be considered BAT under any circumstances. The use of asbestos diaphragms is not BAT.
Technique
Description
Applicability
a
Bipolar membrane cell technique
Membrane cells consist of an anode and a cathode separated by a membrane. In a bipolar configuration, individual membrane cells are electrically connected in series.
Generally applicable.
b
Monopolar membrane cell technique
Membrane cells consist of an anode and a cathode separated by a membrane. In a monopolar configuration, individual membrane cells are electrically connected in parallel.
Not applicable to new plants with a chlorine capacity of > 20 kt/yr.
c
Asbestos-free diaphragm cell technique
Asbestos-free diaphragm cells consist of an anode and a cathode separated by an asbestos-free diaphragm. Individual diaphragm cells are electrically connected in series (bipolar) or in parallel (monopolar).
Generally applicable.
