Burnett and pycnometric (p,Vm,T) measurements for natural gas mixtures

Abstract

Accurate (p,Vm,T) measurements were performed on five natural gas mixtures using a Burnett apparatus and a high pressure, continuously-weighed pycnometer. These measurements were part of a co-operative project sponsored by the Gas Research Institute to establish an internally consistent database of experimental measurements for five representative natural gas mixtures. Burnett results are reported atT=(250, 275, 300, and 325) K for pressures to 11 MPa. Pycnometer results are reported atT=(225, 250, 275, 300, 325, and 350) K for pressures to 70 MPa.
