13 Protocol bij het Verdrag van 1979 betreffende grensoverschrijdende luchtverontreiniging over lange afstand inzake de verdergaande vermindering van zwavelemissies

CONTROL TECHNIQUES FOR OTHER SECTORS

Reported examples are the following:

a) In new kraft pulp mills, sulphur emission of less than 1 kg of sulphur per tonne of pulp AD (air dried) can be achieved;

*) Control of sulphur-to-sodium ratio is required, i.e. removal of sulphur in the form of neutral salts and use of sulphur-free sodium make-up.

b) In sulphite pulp mills, 1 to 1.5 kg of sulphur per tonne of pulp AD can be achieved;

c) In the case of roasting of sulphides, removal efficiencies of 80 to 99% for 10,000 to 200,000 m3/h units have been reported (depending on the process);

d) For one iron or sintering plant, an FGD unit of 320,000 m3/h capacity achieves a clean gas value below 100 mg SO x /Nm3 at 6% 02;

e) Coke ovens are achieving less than 400 mg SOx/Nm3at 6% 02;

f) Sulphuric acid plants achieve a conversion rate larger than 99%;

g) Advanced Claus plant achieves sulphur recovery of more than 99%.
