    re SO2 emission control. Hello Tam, SO2 emissions in a properly-operated cement kiln with a reasonable alkali/SO3 balance are due primarily to increased levels of sulphides and organic sulphur-containing compounds in the raw meal. By 'properly-operated' I mean that the kiln oxygen should be continuously maintained at a level which prevents the
