UOP 381 – Traces of Sulfur in Liquefied Petroleum Gases by the Nickel Reduction Method
This method is for the determination of low concentrations of sulfur in liquefied petroleum gases. The lower limit of detection ranges from 0.2 ppm sulfur in olefin-free butanes to about 20 ppm sulfur in a 100% olefin sample. The sulfur analyzed includes not only volatile compounds, but also high – boiling forms such as dissolved elemental sulfur.
