... to demonstrate, and quantify, diameter effects in single-phase flow. Further, the effects of DRA in two- and three-phase flow have been studied in a D=100mm pipe. The overall conclusion is that the drag reduction increases with the inlet fraction of the liquid that carries the DRA. INTRODUCTION This paper...

... projects (with longer pipeline lengths and with larger pipe diameters) can require even larger slugcatchers (e.g. 8000 to 10000 m3). The presence of a large slugcatcher will guarantee the continuous supply of gas to the downstream gas plant. The available literature on by-pass pigging is limited. Out [1...
