# Commission Implementing Decision (EU) 2016/1032 of 13 June 2016 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the non-ferrous metals industries (notified under document C(2016) 3563) (Text with EEA relevance), Division BAT 27

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

In order to reduce diffuse emissions from Peirce-Smith converter (PS) furnace in primary and secondary copper production, BAT is to use a combination of the techniques given below.
Description of the technique is given in Section 1.10.
Technique
a
Operate the furnace and gas route under negative pressure and at a sufficient gas extraction rate to prevent pressurisation
b
Oxygen enrichment
c
Primary hood over the converter opening to collect and transfer the primary emissions to an abatement system
d
Addition of materials (e.g. scrap and flux) through the hood
e
System of secondary hoods in addition to the main one to capture emissions during charging and tapping operations
f
Furnace located in enclosed building
g
Apply motor-driven secondary hoods, to move them according to the process stage, to increase the efficiency of the collection of secondary emissions
h
Boosted suction systems and automatic control to prevent blowing when the converter is ‘rolled out’ or ‘rolled in’
