What is the reason why the waste sulfuric acid used for drying hydrogen chloride in the polyethylene workshop is black in color?

If it is dry organic matter, sulfuric acid will be black. But dry hydrogen chloride should not be black, right? When chlorine gas is dried upstream, it is transparent.

Where does the hydrogen chloride come from in the polyethylene workshop?
