While typical gas transmission pipelines operate at pressures up to about 1500 psi, a number of applications in North America and Australia use or plan pipelines operating at significantly higher pressures. Often, these operations are referred to as “dense phase”. These are, in general, operating conditions above the critical pressure and temperature of the gas. Several existing installations are described and analyzed. We will explain the underlying reasons why higher pressure pipelines are considered as well as the tradeoffs compared to traditional, lower pressure pipelines. This involves, in particular, the impact of a larger effort to bring the gas to thehigher pressure. The impact on compressor and driver selections is also considered, in particular the impact of the higher power density of the centrifugal compressors at higher pressures.
