Black oil correlations are typically used when a limited amount of oil and gas information is available in the system. Oil and gas fluid properties are calculated from correlations with their respective specific gravity (as well as a few other easily measured parameters). Black Oil is not typically used for systems that would be characterized as gas-condensate or dry gas, but rather for systems where the liquid phase is a non-volatile oil (and consequently there is no evolution of gas, except for that which is dissolved in the oil). In this Tutorial, two black oil streams at different conditions and compositions are passed through a mixer to blend into one black oil stream. The blended black oil stream is then fed to the Black Oil Translator where the blended black oil stream data is transitioned to a HYSYS material stream. A flowsheet for this process is shown below. Figure 1.1 Black Oil 1-3 1-3 The following pages will guide you through building a HYSYS case for modeling this process. This example will illustrate the complete construction of the simulation, from selecting the property package and components, to installing streams and unit operations, through to examining the final results. The tools available in the HYSYS interface will be used to illustrate the flexibility available to you. The simulation will be built using these basic steps: 1. Create a unit set and set the Black Oil default options. 2. Select the components. 3. Add a Neotec Black Oil property package. 4. Create and specify the feed streams. 5. Install and define the unit operations prior to the translator. 6. Install and define the translator. 7. Add a Peng-Robinson property package. 1-4 Setting the Session Preferences 1-4 1.2 Setting the Session Preferences 1. To start a new simulation case, do one of the following: • From the File menu, select New and then Case. • Click the New Case icon. The Simulation Basis Manager appears: Next you will set your Session Preferences before building a case. Figure 1.2 New Case icon Black Oil 1-5 1-5 2. From the Tools menu, select Preferences. The Session Preferences view appears. You should be on the Options page of the Simulation tab. 3. In the General Options group, ensure the Use Modal Property Views checkbox is unchecked so that you can access multiple views at the same time. 1.2.1 Creating a New Unit Set The first step in building the simulation case is choosing a unit set. Since HYSYS does not allow you to change any of the three default unit sets listed (i.e., EuroSI, Field, and SI), you will create a new unit set by cloning an existing one. For this example, a new unit set will be made based on the HYSYS Field set, which you will then customize. To create a new unit set, do the following: 1. In the Session Preferences view, click the Variables tab. 2. Select the Units page if it is not already selected. Figure 1.3 1-6 Setting the Session Preferences 1-6 3. In the Available Unit Sets group, highlight Field to make it the active set. 4. Click the Clone button. A new unit set named NewUser appears. This unit set becomes the currently Available Unit Set. 5. In the Unit Set Name field, rename the new unit set as Black Oil. You can now change the units for any variable associated with this new unit set. In the Display Units group, the current default unit for Std Gas Den is lb/ft3. In this example we will change the unit to SG_rel_to_air. Figure 1.4 The default Preference file is named hysys.PRF. When you modify any of the preferences, you can save the changes in a new Preference file by clicking the Save Preference Set button. HYSYS prompts you to provide a name for the new Preference file, which you can load into any simulation case by clicking the Load Preference Set button. Black Oil 1-7 1-7 6. To view the available units for Std Gas Den, click the drop-down arrow in the Std Gas Den cell. 7. Scroll through the list using either the scroll bar or the arrow keys, and select SG_rel_to_air. 8. Next change the Standard Density unit to SG 60/60 api. Your Black Oil unit set is now defined. Figure 1.5 1-8 Setting the Session Preferences 1-8 1.2.2 Setting Black Oil Stream Default Options To set the Black Oil stream default options: 1. Click on the Oil Input tab in the Session Preference view. 2. In the Session Preferences view, select the Black Oils page. 3. In the Black Oil Stream Options group, you can select the methods for calculating the viscosity, and displaying the water content for all the black oil streams in your simulation. For now you will leave the settings as default. 4. Click the Close icon (in the top right corner) to close the Session Preferences view. You will now add the components and fluid package to the simulation. Figure 1.6 Close icon Black Oil 1-9 1-9 1.3 Setting the Simulation Basis The Simulation Basis Manager allows you to create, modify, and manipulate fluid packages in your simulation case. As a minimum, a Fluid Package contains the components and property method (for example, an Equation of State) HYSYS will use in its calculations for a particular flowsheet. Depending on what is required in a specific flowsheet, a Fluid Package may also contain other information such as reactions and interaction parameters. You will first define your fluid package by selecting the components in this simulation case. 1.3.1 Selecting Components HYSYS has an internal stipulation that at least one component must be added to a component list that is associated to a fluid package. To fulfil this requirement you must add a minimum of a single component even when the compositional data is not needed. For black oil streams, depending on the information available, you have the option to either specify the gas components compositions or the gas density to define the gas phase of the stream. 1-10 Setting the Simulation Basis 1-10 To add components to your simulation case: 1. Click on the Components tab in the Simulation Basis Manager. 2. Click the Add button. The Component List view is displayed. In this tutorial, you will uploads/s1/ hysys-upstream-guide.pdf
