BAT for the production of viscose fibres

Additionally to the generic BAT (see Section 13.1), for the production of viscose fibres, the following BAT have to be taken into account. 

BAT is to condense the exhaust air from spinning streets to recover CS2 and recycle it back into the process (see Section 12.7.2) 

BAT is to recover CS2 from exhaust air streams through adsorption on activated carbon (see Section 12.7.3) 

Depending on the concentration of H2S in the exhaust air, different technologies are available for the adsorptive recovery of CS2. 

BAT is to apply exhaust air desulphurisation processes based on catalytic oxidation with H2SO4 production (see Section 12.7.4)
