standard by GPA Midstream Association, 2020
Full Description
GPA 2177-20 is intended for the analysis of demethanized liquid hydrocarbon streams containing nitrogen/air and carbon dioxide, and purity products such as ethane/propane mix that fall within compositional ranges indicated in the standard.
This method is limited to mixtures containing less than 5 mole percent of heptanes and heavier fractions (20 mole percent of hexanes and heavier fractions).
