Bubble Point Measurements of Neopentane + Ethane Mixtures

March 14, 2019
Author(s)
Elisabeth Mansfield, Vladimir Diky
Bubble point measurements have been taken on three compositions of neopentane + ethane systems. The results are modeled with a Peng-Robinson equation with symmetrical mixing rule and a Helmholtz-energy based 4-parameter model. Interaction parameters for
