.... The impact on transportation efficiency in terms of energy consumption as well as the impact on the transport capacity of a pipeline where the equipment was sized originally for natural gas transport, are assessed. Introduction and Background The increased use of renewable energy will require...

... operating pipelines are presented. The characteristics of these pipelines are very diverse: internal diameters vary from 0.4 m to 1 m, different DRAs are used, and different types of liquid (oils, oil products and gas-condensates) are pumped. concentration efficiency distribution logic programming...

... ABSTRACT Predicting the efficiency of a DRA is still dependent on the use of models developed through field tests. Two forms of the model are widely used for liquid pipelines, one correlates Drag Reduction (DR) as a function of DRA concentration only, and the other correlates DR as a function...

... basic hydraulic pump equations. Actual system efficiency was used. Both maximum surge pressure and pressure rise rate are calculated each model time step. This same method can be used for other energy recovery systems hydraulic analysis. In this study, a high-pressure feed pump with a discharge...

... ABSTRACT One of the key goals of pipeline hydraulic optimization is the capability to minimize fuel consumption of gas turbine driven centrifugal compressors. This requires an accurate, and computationally efficient method to calculate the fuel consumption of a gas turbine driven centrifugal...
