What are the sulfur specifcations for propane?
The Gas Processors Association (“GPA”) provides product specifications for liquefied petroleum gases. These specifications may be found in Figure 2-1 (GPA Liquefied Petroleum Gas Speficications – GPA Standard 2140-92) of the Engineering Data Book (10th Edition, 1994) published by the Gas Processors Suppliers Association. Total sulfur standards are provided in units of ppmw. For commercial propane, the standard is 185 ppmw as S (254 ppmv as S, 239 ppmv as H2S).
