  4. Hysys Utilities • Boiling Point Curves • Obtain laboratory-style distillation results for streams. • Critical Property • Calculate true and pseudo critical properties for streams. • Envelope Utility • Show critical values and phase diagrams for a stream. • Pinch Utility • Optimize the use of process heat exchange and utilities for heat exchangers,LNG's,coolers and heaters. • Property Table • Examine stream property trends over a range of conditions. • Tray Sizing • Size/rate existing sections or full towers. • Vessel Sizing • Size and cost installed Separator Unit Operations. • Pipe Sizing • Calculate the pressure drop or the pipe diameter. • Pipe Segment • Simulate a wide variety of piping situations. 054402 Design & Analysis II

  5. Hysys Utilities (continued) • Boiling Point Curves The Boiling Point Curves utility, which will generally be used in conjunction with characterized oils from the Oil Manager, allows you to obtain the results of a laboratory style analysis for your simulation streams. Simulated distillation data including TBP, ASTM D86, D86 (Corr.), D1160(Vac), D1160(Atm) and D2887 as well as critical property data for each cut point and cold property data are calculated. The data can be viewed in tabular format or graphically. The object for the analysis can be a stream, a phase on any stage of a tray section, or one of the phases in a separator, in a condenser or in a reboiler. You select the basis for the calculations and you can specify the boiling ranges for the simulated distillation data. 054402 Design & Analysis II

  6. Hysys Utilities (continued) • Critical Property The Critical Property Utility calculates both the true and pseudo critical temperature, pressure, volume and compressibility factor for a fully defined stream. Before the Critical Property Utility is accessed, set up a Fluid Package using the Peng Robinson property method and the required components. Install the stream Feed. 054402 Design & Analysis II

  7. Hysys Utilities (continued) • Envelope Utility The Envelope utility allows you to examine relationships between selected parameters,for any stream of known composition,including streams with only one component. Vapor-Liquid Envelopes may be plotted for the following variables: •Pressure-Temperature •Pressure-Volume •Pressure-Enthalpy •Pressure-Entropy •Temperature-Volume •Temperature-Enthalpy •Temperature-Entropy Since the Envelope is calculated on a dry basis,you must be careful when applying the utility to multi-component mixtures that contain H 2 O or any other component which can form a second liquid phase. Note also that the Envelope is restricted to the Peng Robinsonand Soave Redlich Kwongequations of state. 054402 Design & Analysis II

  8. Property Table The Property Tableutility allows you to examine property trends over a range of conditions in both tabular and graphical formats. Using a stream of known composition,you target two independent variables and their respective ranges of interest. The range of each independent variable is distinct and can be set as either an incremental range or a selection of specific values.Next,you relate which dependent variables are to be displayed at each combination of the independent variables. Hysys Utilities (continued) • Pinch Utility Pinch technology is a methodology which is used to optimize the use of process heat exchange and utilities in complicated processes. The HYSYS Pinch utility provides the necessary tools to apply the pinch principles in the design of efficient heat exchanger networks. 054402 Design & Analysis II

  9. Vessel Sizing The Vessel Sizing utility allows you to size and cost installed separator, tank and reactor unit operations. You can select a vertical or horizontal orientation for the separator. To obtain a more effective analysis for your vessel, changes can be made to the default parameters provided by HYSYS. Hysys Utilities (continued) • Tray Sizing With the Tray Sizing utility you can perform design and rating sizing calculations on part or all of a converged column. Packing or tray information can be specified relating to specific tower internals such as tray dimensions or packing sizes,design flooding and pressure drop specifications.Results include tower diameter,pressure drop,flooding, tray dimensions,etc. 054402 Design & Analysis II

  10. Pipe Segment The pipe segment is used to simulate a wide variety of piping situations ranging from single/multiphase plant piping with rigorous heat transfer estimation,to large capacity looped pipeline problems. It offers two pressure drop correlations:one developed by Gregory,Aziz and Mandhane,and the other by Beggs and Brill. Four levels of complexity in heat transfer estimation allow you to find a solution as rigorous as required while allowing for quick generalized solutions to well-known problems. Hysys Utilities (continued) The Pipe Sizing utility allows you to calculate the Pressure drop by defining the pipe Diameter and Schedule or to size the pipe Diameter by defining the Pressure dropand Schedule. The Pipe Sizing utility work with one or two phase stream. In the case of two phase stream it state also the flow regime. • Pipe Sizing 054402 Design & Analysis II
