A program for investigating gaseous and liquid properties of methane is being conducted at the Cryogenics Division of the U.S. National Bureau of Standards under a grant from the American Gas Association. Precision measurements have been made for vapor pressures, melting pressures, and pressure-volume-temperature (PVT) relationships of LNG. Future measurements will include PVT relations in compressed gaseous methane and specific heat determinations for both gaseous and liquid phases. Temperatures of all these measurements range from 90.7 K (the triple point) to 300 K; pressures vary between 0.1 and 35 Mnewtons sq m (1 Mnewton/sq m = 145 psia). A publication, the "LNG Quarterly", listing articles and papers from the recent LNG literature, is available by subscription. A concurrent NBS project is investigating flowmeter design, including unusual metering problems with LNG.
