processing for treating talc to remove the impurties

Mercaptans

As stated earlier, amine treating is not effective for the removal of mercaptan There are two options for treating mercaptans In each option, the mercaptans are first oxidized to disulphid One option, extraction, dissolves the disulfides in caustic and removes them The other option, sweetening, leaves the converted disulfides in the ....
