（六）PIPEFLO 7 Features and Applications

Graphical User Interface (GUI) and Convenient Self-Guiding Data Entry:A Windows GUI has been implemented for ease of data entry. Drag and drop pipeline items onto the schematic and connect them. Windows Explorer type layout allows easy inspection of properties for each item. Fly-by display for calculated results allows for fast efficient modelling.
Handles Compositional, Black-oil, Non-compositional, and Steam Systems: For compositional systems, PIPEFLO 7 models the required fluid P-V-T behaviour according to the user- selected equation of state which are provided under special license from Hyprotech. Phase envelopes can be requested at any point in the pipeline system. Additional equations and correlations are available to determine transport properties. As with selection of the pressure loss technology, PIPEFLO 7 provides recommended choices based on the user's specified fluid system. For non compositional systems (when detailed fluid composition or characteristic data are not available),the fluid behaviour can be modelled by a selection of black-oil correlations developed from regional-based oils or using a simplified approach in which it is assumed that no phase change occurs between the liquids and gases. This is especially useful for low liquids systems when detailed fluid analyses are not available or preliminary work is being performed. Single component multiphase systems such as saturated steam, can also be handled, based on a pressure-enthalpy balanced algorithm.
Perform Calculations with an Assigned Temperature Profile:This a particularly useful option to assess the sensitivity of the pipeline model to flowing fluid temperatures.
Estimate liquid slug size when pigging: PIPEFLO 7 uses an approximation technique for estimating this important parameter that should be sufficiently accurate for most slug catcher sizing calculations.
Plotting & Output Processing: Select a path through the pipeline system on screen and right click to plot any of the calculated gradients along that path. Use the output generator to choose the calculated results required in the report. The resulting HTML output file can then be browsed using a standard browser within interior links which give direct access to the component details in the pipeline system.
