# Commission Implementing Decision (EU) 2017/2117 of 21 November 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of large volume organic chemicals (notified under document C(2017) 7469) (Text with EEA relevance), Division BAT 85:: In order to reduce the amount of hazardous waste being sent for disposal and to increase resource efficiency, BAT is to use all of the techniques given below.

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

Technique
Description
Applicability
a.
Hydrogenation of acetylene
HCl is generated in the EDC cracking reaction and recovered by distillation.
Hydrogenation of the acetylene present in this HCl stream is carried out to reduce the generation of unwanted compounds during oxychlorination. Acetylene values below 50 ppmv at the outlet of the hydrogenation unit are advisable
Only applicable to new plants or major plant upgrades
b.
Recovery and reuse of HCl from incineration of liquid waste
HCl is recovered from incinerator off-gas by wet scrubbing with water or diluted HCl (see Section 12.1) and reused (e.g. in the oxychlorination plant)
Generally applicable
c.
Isolation of chlorinated compounds for use
Isolation and, if needed, purification of by-products for use (e.g. monochloroethane and/or 1,1,2-trichloroethane, the latter for the production of 1,1-dichloroethylene)
Only applicable to new distillation units or major plant upgrades.
Applicability may be restricted by a lack of available uses for these compounds
