BURNETT AND PYCNOMETRIC (P,V-M,T) MEASUREMENTS FOR NATURAL-GAS MIXTURES

Accurate (p,V-m, T) measurements were performed on five natural gas mi xtures using a Burnett apparatus and a high pressure, continuously-wei ghed pycnometer. These measurements were part of a co-operative projec t sponsored by the Gas Research Institute to establish an internally c onsistent database of experimental measurements for five representativ e natural gas mixtures. Burnett results are reported at T = (250, 275, 300, and 325) K for pressures to 11 MPa. Pycnometer results are repor ted at T = (225, 250, 275, 300, 325, and 350) K for pressures to 70 MP a.
