Organization: ASTM International
Publication Date: 29 July 2002
Status: active
Page Count: 4
scope:

This method is an extraction procedure that, when used in conjunction with UOP Method 959, allows the determination of ammonia in liquid hydrocarbon streams. Other nitrogen species, if present, are not detected by this method. This procedure yields quantitative results and has been tested in the range of approximately 0.5 to 10 mass-ppm ammonia. Higher concentrations can be determined by dilution of the aqueous extract as noted in UOP Method 959, or by performing the extraction using a larger volume of water and/or a smaller sample size (preferred if the ammonia level can be estimated).
