A gaseous or liquid propellant is used to push the pig through the system. This strategy avoids rinsing loss of valuable product, provides reduction of adverse environmental impacts, and gains high efficiency for less investment. The book describes clearly and methodically the important basic equipment required for the planning and design of pigging units. Many practical examples are shown for the operation of industr 606 $aPipeline pigging 615 0$aPipeline pigging. 676 $a621.8/672 700 $aHiltscher$b Gerhard$01757310 701 $aMuhlthaler$b Wolfgang$01757311 701 $aSmits$b Jorg$01757312 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910876892203321 996 $aIndustrial pigging technology$94195126 997 $aUNINA
