DESIGN II Rigorous process simulation for chemical and hydrocarbon processes including refining, refrigeration, petrochemical, gas processing, gas treating, pipelines, ammonia, methanol and hydrogen facilities The Easy Way To Do Simulation Microsoft Windows has become the standard for desktop graphical computing and WinSim's DESIGN II for Windows was the first process simulator developed specifically for Windows computing. DESIGN II for Windows has been leading the way in this technology since 1991. Instant Usability One click and you'll be convinced: DESIGN II for Windows is the easy way to do simulation. WinSim’s original process simulator for Windows is intuitive and inter-operable with other Windows applications. Its look and feel provides an instant familiarity for experienced Windows users. The graphical interface means there are no special commands or function keys to remember. Just draw your flowsheet with point-and-click simplicity. Double click on flowsheet equipment and streams for specification dialog boxes to appear. Once your flowsheet is complete, DESIGN ll for Windows will even validate your input before computing the simulation results. Export stream and equipment results to Microsoft Excel, or display the complete results as a text file. The simulation is fast, easy, and error free. The Proven Pioneer of Simulator Engines - DESIGN II With a thirty plus year history of continued development and refinement, DESIGN II has long been a leader in process simulator innovation. Many DESIGN II features, such as Inline FORTRAN and rigorous column calculations, have set the standard for process simulation. Because of its proven strengths, DESIGN II is the simulation engine underlying DESIGN II for Windows. DESIGN II is a powerful and comprehensive process simulation computational engine, which performs complete heat and material balance calculations for a wide variety of pipeline and processing applications. The simulator’s easy-to-create flowsheets allow process engineers to concentrate on engineering, rather than computer operations. A minimum amount of input is required to utilize DESIGN II for Windows. Furthermore, the DESIGN II keyword commands that are necessary are fully supported via a free-form text window in DESIGN II for Windows. WinSim’s simulator offers advanced features, such as sizing and rating of heat exchangers and separators, within the flowsheet. The DESIGN II for Windows database contains 880 pure components, and others can be added via CHEMTRAN. Also included is a crude library with 38 world crudes, already characterized and at your fingertips. |

| A Perfect Fit for Any Environment Whether the situation requires a quick answer to a simple pressure drop problem or a complete simulation model of a large plant for operational engineering, DESIGN II for Windows is the perfect combination of power and ease-of-use. The size and complexity of the flowsheet, including the number of unit operations, streams, and components, is limited only by the capacity of the computer on which the flowsheet is constructed. The flowsheet can be built using a point-and-click Windows interface, keyword commands, or a combination of both options. |

| Mixed Amines DESIGN II for Windows offers the industry's foremost rate-based single and blended amine simulator for gas treating applications. Rate Based Column Models Accurate kinetic models are used to determine reaction rates and their impact on column operation. Rigorously accounting for the kinetic and hydrodynamic effects in selective gas treatment allows for the proper design and operation of treating units. Avoid under design (insufficient CO2 pickup) or over design (excessive CO2 removal, loss of selectivity and possible increased content of H2S in sweet gas). Thermodynamic models (Kent-Eisenberg or Deshmukh-Mather) rigorously account for the ionic nature of the solvents, rates of mass transfer, heat transfer coefficients, and driving forces. Reaction kinetics will determine mass transfer enhancement factors and selective removal rates. Selective Stripping and Solvent Formulation By simulating processes that employ either a single amine or a binary blend of MEA, DEA, DGA, DIPA or MDEA as solvents, DESIGN II FOR WINDOWS allows the selective removal of H2S and CO2. The user may, for example, debottleneck DEA columns or lower the CO2 content of sweet gas from MDEA columns. This allows the engineer to reduce their amine operating cost by formulating a solvent that best meets their particular needs. Real Column Simulation Both trayed and packed columns are modeled by describing their actual configuration. Packed columns need not be converted to trays (HETP) or the actual trays to equilibrium trays; DESIGN II for Windows calculates the actual mass transfer in a section of packing or on a real tray. You can specify the pressure drop over the entire column, the pressure drop per tray, or request the program calculate the pressure drop. The column parameters are outlined below. |

| Petroleum Crude Processing DESIGN II for Windows offer engineers rigorous simulation and optimization of one or more distillation columns receiving high hydrocarbon feeds with complex heat trains for maximum product recovery and heat loss minimization. Crude Feed Streams DESIGN II for Windows can simulate multiple crude feeds into the process. The hydrocarbon feeds are typically characterized by TBP or ASTM D-86/1160 distillation curves. DESIGN II allows entry of as much information as you have for your feed(s), from the minimum required details to define a feed (distillation curve, bulk gravity, temperature, pressure and flow rate) to more elaborate data such as sulfur weight percent curves, viscosity curves, pour point and metals content. Refine Columns The Refine Columns are used for rigorous simulation of distillation columns receiving high hydrocarbon-content feeds. Many common refinery units can be modeled including pre-flash towers, atmospheric columns, vacuum columns, FCC main fractionators and quench columns. Multiple side strippers, pumparounds, and side heaters / coolers can be added to the main column configuration for a rigorous simultaneous calculation. Refine Columns can be used for designing or modifying refinery fractionators with very good results. It is possible to duplicate the operation of existing units within a few percent of actual plant data. The simulator can match many important operational parameters, such as tower temperatures, reflux ratio, product rates and property specifications. Significant discrepancies are usually due to inaccuracies in data collection, but may be due to operational problems. In these cases a Refine Column may be used to identify the source of the problem and determine the solution.

| Heat Exchangers DESIGN II for Windows offers engineers rogorous simulation of many types of heat exchangers. Shell and Tube Heat Exchangers The Shell and Tube heat exchanger module simulates two process streams exchanging heat with each other. This usually involves a heat recycle situation with one of the streams coming from downstream in the process. DESIGN II has built-in rating calculations for shell and tube heat exchangers. Any single phase counter-current exchanger, and any type E or type F shell two- phase exchanger, can be rated in the flowsheet. The rating calculations automatically handle boiling or condensation occurring in either the shell-side or the tube-side of a heat exchanger. No special commands are required to indicate a two-phase stream. Plate-Fin Heat Exchangers The Plate-Fin Exchanger module can be used to simulate multiple stream exchangers. This type of exchangers allows multiple hot and cold streams to exchange heat with a maximum heat transfer surface area. The module calculates the heat and material balance from known input stream information and the specifications to be met. DESIGN II has built-in rating calculations for Brazed Aluminum Plate-Fin heat exchangers. The rating calculations automatically handle boiling or condensation occurring in either the hot-side or the cold-side streams of the heat exchanger. |

| Multiple Pass Shell and Tube Heat Exchangers The LNG Exchanger module is used to specify heating or cooling of up to twenty tube side streams and twenty shell side streams. Each tube-side stream can have either the same outlet specification or entirely different specifications. Tube side outlet streams may be recycled back and mixed with a single shell side feed stream. Air-Cooled Heat Exchanger The air-cooled heat exchanger module allows you to rigorously model and rate air coolers or air condensers. You can specify the process side and/or the air side of the air cooler. The air side of the air cooler can be modeled as a utility stream (automatically calculated) or it can be a process stream (specified conditions). You can specify all the physical characteristics of the air cooler (tubes, fins, fans, power, passes, etc) or use the default values when rating is calculated. Refrigerant Heat Exchanger Refrigerant exchangers are similar to counter-current heat exchangers with the refrigerant entering at the bubble point and leaving at the dew point. The temperature or pressure of the refrigerant is calculated along with the flow rate required and all corresponding properties. The properties of the process stream out are calculated. The duty, area, and corrected LMTD are calculated and reported in the equipment summary. Water-Cooled Heat Exchanger Water-cooled exchangers are handled as single-stream exchangers. The water temperatures in and out are specified for the heat exchanger, rather than specifying the stream temperature and pressure. The amount of water is calculated as part of the heat exchanger output, in lieu of specifying it on a flow command or reporting it in the final stream summaries. Therefore, the water stream in and out of the water-cooled exchanger does not need to be included as part of the flowsheet. Also, water does not have to be added as a component in the flowsheet simulation. The amount of water required to condense the process stream is calculated along with the duty, area, corrected LMTD, and outlet stream properties for the process stream. Single Stream Temperature Change In many process simulations, only one side of the exchanger is of interest. For example, you may be interested only in process-stream temperature adjustment, instead of the amount of utility required for the heat exchange. Usually, exchangers that use a heating or cooling substance to adjust the temperature of a process stream can be modeled by specifying only one stream in and one stream out. This greatly reduces the complexity of the simulation. In this case, the duty and/or temperature out of the exchanger are calculated along with all the properties of the outlet stream. |

| Visual Basic Interface The DESIGN II simulator kernel can be embedded in your company's in-house software for flashes and property calculations. Microsoft Visual Basic Interface DESIGN II has a complete interface for any Visual Basic program (or VB compatible environment) to directly call the flash methods in the simulator kernel. The Design II DLL is a dynamic link library that contains 100% of the functionality of Design II for Windows in a form that can be used directly by other programs. All of the chemical compounds, property calculations and equipment simulations are included in the DLL, but only those parts needed most often flashes and property calculations - are exposed for each client. This permits WinSim to charge much less for Design II DLL than for Design II for Windows. Clients can provide Design II DLL’s as a part of their SFA packages for hundreds of laptops at affordable prices. Visual Basic is the glue Microsoft’s Visual Basic (VB) is a programming methodology that lets programmers quickly create easy-to-use programs that have a Windows look-and-feel. A great advantage of VB is that it can "call" DLL’s. VB is the glue that holds together the manufacturer’s classic detailed design programs, many written in Fortran, with needed parts of WinSim’s world-class calculation engine to give a better, more accurate and much quicker “quotation machine”. Targeted manufacturers and suppliers The Design II DLL is targeted at those companies with internal, proprietary programs for detailed design of piping, equipment or suppliers for process plants, but need a key element of Design II such as its extensive thermodynamic property methods and database. Examples include pump, compressor and heat exchanger manufacturers and consumable suppliers such as those that sell mixed amines for gas treating. Imagine How WinSim’s Powerful Calculation Engine Can Be Combined With Yours Sales force automation is but one of the many ways the Design II DLL can be used. For example, the piping and detailed equipment design departments of E & C companies can incorporate rigorous thermodynamic and fluid flow methods from Design II into their design programs. Anytime some of the powers of a world- class simulation engine can be combined with your programs using VB, Lab-View¨ or other glue that can call DLL’s, the possibilities can only be imagined and only by you. Microsoft Visual C++ Interface In addition to the Visual Basic interface, DESIGN II for Windows also includes an interface for embedding the DESIGN II DLL in Visual C++ programs. A sample Visual C++ application calling the DESIGN II simulator kernel is also included in the standard software distribution. Microsoft Excel VBA Interface In addition to the Visual Basic interface, the DESIGN II DLL can be called from any Microsoft Excel spreadsheet. A sample Microsoft Excel spreadsheet for calling the DESIGN II simulator kernel is also included in the standard software distribution. Sample VB Application with source code A sample Visual Basic application using the DESIGN II DLL has been included in the software distribution in the BIN subdirectory. The name of the sample application is D2PROPS. Full source code is included in the D2PROPS.FRM file.Ê The Visual Basic project files of D2PROPS.VBP and D2PROPS.VBW are also included.
