2 1. Introduction The Petrospace Desktop Refinery Simulation is a proven and advanced refinery training tool available for the first time as a desktop version. Developed for refinery trainers, it is however of great relevance to all involved in refinery operations and maintenance Petrospace is a collection of refinery plant and equipment linked together as a functioning interactive whole and arranged for maximum training and demonstration opportunities. Users can navigate freely through the virtual refinery using keyboard and mouse, or choose to be transported to key equipment by mouse click. They can choose to see the inner workings of key apparatus via a visualization option: an enormously powerful feature in aiding understanding. Virtual copies of pumps, heat exchangers, column, furnace, gas compressor, tanks, safety equipment, valves, etc. are actual working copies. Most valves, levers and switches can be activated by mouse click, causing the relevant response of that equipment. Users can pre-select various operational parameters, and trigger equipment malfunctions and emergencies (eg. oil leaks and fires), by means of easy-to-use drop-down menus. This manual is not a set of training exercises. Users are free to devise their own demonstration and training content depending upon individual training objectives. This manual serves to explain what is contained in the Petrospace simulation and which training tasks can be accomplished. Users are ultimately responsible for the training content which they devise and deliver to their trainees, and Phenomatics accepts no liability in this respect. 2. System requirements (minimum hardware specifications) Petrospace needs an OpenGL-capable graphics card. OpenGL works with most of today s graphics chips. However, many notebook computers and older desktop PCs, as well as some office PCs do not offer enough graphics processing power to run Petrospace. If the trial version runs well on your system, your PC is powerful enough for Petrospace. Minimum System Requirements CPU 2 GHz single core CPU Main memory 2 GB (4 GB recommended on Windows Vista and Windows 7) Free hard disk space 480 MB Graphics card OpenGL capable graphics card, i.e. NVIDIA Geforce FX5900 or better 2

3 ATI Radeon X800 or better IBM GMA X3000 or better Operating system Sound a minimum of 128 MB of dedicated graphics memory Windows XP with Service Pack 2 or Windows Vista (32 or 64 bit edition) or Windows 7 (32 or 64 bit edition) Onboard sound chip or sound card 3. Installing the Petrospace software Petrospace is easy to install and brings everything it needs in a single package. You will need to have at least 480 MB of free space on your hard disk to install it. You will also need the necessary user permissions on the computer where you want to install Petrospace, so you might need to check this with your system's administrator. 1. Double click the file PetrospaceSetup.msi to start the installation process. This is a Windows Installer package containing Petrospace. Under Windows Vista and Windows 7 you will get a security warning by Windows that the manufacturer of the software could not be verified. This is normal and you can safely click the "Execute" button (it only means that the software has not been registered with Microsoft). 2. The Petrospace Setup Wizard will come up. Click "Next". 3. The Setup Wizard will ask you where to install Petrospace. We recommend to install it in the default folder provided by the Setup Wizard 3

4 ("C:\Program Files\Phenomatics\Petrospace"). But Petrospace will also work from a different folder. You can also choose how the Setup Wizard shall set the permissions to use Petrospace on this computer ("Everyone" for all users or "Just me"). Click on "Next". 4. The Setup Wizard will finally ask you to confirm the installation settings by clicking on "Next". The installation will start. 5. Users of Windows Vista and Windows 7 may get a warning message by the Windows User Access Control (UAC) during the installation process. Tell UAC to allow Petrospace to install itself on your computer. 4

5 Changing to the purchased version After purchasing a license for Petrospace, you will receive a license key by e- mail which will turn the trial version (even if your trial period has already expired) into the purchased version, so you don t need to install Petrospace again. Start Petrospace. Click on the button Enter Key. Another message box appears with two fields. Enter the name you registered with in the Name field and the key you received by into the key field. The key is a combination of letters and digits in multiple groups of 6 characters. Make sure the name matches the name you registered at our web shop (or the name sent along with the key). The key will be rejected if you use a different name! 4. Getting started 4.1.

Press n or F1 again to quit TO QUIT THE SIMULATION COMPLETELY, PRESS Esc 4.5 Interacting with equipment 10

11 Simply navigate the cross-hairs onto the desired valve, switch, lever, etc and hold down the mouse button. On most equipment the rule is Left mouse button to open valves. Right mouse button to close valves. Or single click on the middle mouse button (or wheel) to fully-open or fully-close valves. 4.6 Menu mode (drop-down menus) Menu Mode (M mode) can be activated for every major piece of equipment. In M mode, the user can easily set-up various pre-determined situations (for example pump seizure, oil leak, or adjust oil levels, etc). To enter M Mode press space bar Select the required piece of apparatus from the tabs at the bottom of the screen Select which parameters are to be set, by choosing from the drop-down menu 11

12 Full navigation in the refinery is only restored when M Mode is quit (press Space again). 4.7 Visualizations For certain key equipment, it is possible to visualize the interior workings by selecting from the drop-down menus. This is dynamic real-time visualization: the visualization responds immediately to changes in the operating parameters which are set or triggered by the user. When it is no longer necessary to visualize a piece of equipment, the visualization should be de-selected in order to conserve computing power, and maximize the quality of the Petrospace user experience. Visualization of selected equipment can be triggered (drop-down menu): 12

34 Thermo-syphon sealing oil system G414 The procedure for filling the sealing oil is identical to that shown above for G412 and G413. Manometers Every manometer can be tested by means of the manometer lever. The correct operation of the manometer can be checked: with the valve leading to the manometer closed, the reading falls when the manometer lever is closed. The reading rises again after the manometer lever and the valve are opened again. 7 Refinery start-up top gas condensate steam top product cooling water inlet cooling water return bottom product feedstock fire ext. steam F 401 E 427 A E 427 B G 5814 F 411 E 430 B G 401 A E 430 A G 401 B D 406 G 412 A G 413 A F 5818 G 412 B G 413 B B 404 F 421 E 429 G 414 A Steam trap G 417 A G 417 B G 414 B Opening all lines from battery limit Follow the overhead pipes to locate the battery limit at the refinery perimeter or press Space, select battery limit and press go-to.

35 Opening the line feedstock from tank at the battery limit. Feedstock to distillation column After a few seconds there is a clearly-audible noise, and a rise of the pressures at the heat exchangers E 430 A/B and a rise in the suction pressure of the pump G 401. After opening of the feedstock line, 2 minutes are available to prepare the pump G 401 for start-up. If this time is exceeded, the buffer tank F 401 fills itself to 100%. When the pump G 401 is in use, the column D406 fills slowly. Within 2 minutes the sump pump G 414 must be taken into operation, otherwise the level in the column rises to 100%. The top product coming from the delivery side of G 413 A/B can be switched between the inlet pipe for use in tank F 401, or to the battery limit. 35

36 To battery limit To tank F401 From pump G413 From heat exchanger E430 Triggering condensation: The user has to decide on the correct timing to trigger condensation (of top product). Top product appears in the tank F411 only after the user has selected trigger condensation in the distillation column drop-down menu. In the start-up Refinery Scenarios refinery running and refinery running except gas compressor, the condensation is already triggered. 8 Furnace B404 start-up In this simulation, there are both a furnace and an evaporator (E429) as distinct options. Normally, only one of these options would be present. 36

37 In the start-up Refinery Scenarios refinery stopped and refinery stopped except G401, the furnace may be started-up as below. In start-up Refinery Scenarios refinery running and refinery running except gas compressor, the furnace is already in operation. Quantity of the pump G 401 (above 4 ) 37

Note that it will take about 60 seconds for the visualization to initialize after selecting it in M Mode. Three malfunctions can be activated: Overheating will overheat the bottom product which will then propagate slowly to the top of the column. This can be noticed by a growing percentage of brown spheres (bottom product) on each tray. Flood at sump will flood the column with liquid starting from the bottom. Flood at tray will flood the column with liquid starting at the second bubble cap tray. The following can be triggered (drop-down menu): (Press space for M Mode. Select Dist. Column.

Software trouble shooting Visualizations Visualizations require substantial computing power, so you should activate only one visualization at a time and give the simulation a few seconds to initialize itself and create equilibrium. Initialization Some visualizations need time to initialize themselves correctly and reflect the true state of the apparatus after they have been activated. The following table lists the visualizations and the maximum time it takes for them to reflect the true state of the apparatus after activation: apparatus/visualization maximum time for initialization Pump G401A 5 seconds Furnace inside - Steam trap 5 seconds Distillation column and evaporator 60 seconds Heat exchanger E427 - Gas compressor (gas flow visualization) 5 seconds Gas separator 7 seconds Graphics/Speed We recommend using Petrospace with a screen resolution between 1024 x 768 and 1920 x It will run on higher resolutions, but this will put more strain on your graphics card. It will also work with lower resolutions, but you may experience problems using all functions in the menu mode. It is recommended to close all other applications before starting Petrospace. Fullscreen vs. windowed mode Petrospace will always start in full screen on your primary display. If you need to switch to a different application (e.g. your client) during your Petrospace session, you can press the f key (fullscreen) to switch to a windowed mode. However, Petrospace can t be operated correctly in windowed mode. To switch back to fullscreen, move your mouse into the Petrospace window (and click the left mouse button to set the Windows focus on Petrospace) and press f again. General measures to improve graphics speed 74

75 If Petrospace runs jerky or is too slow, you can try switching to a lower screen resolution. Petrospace will always use the current resolution of your Windows desktop. You can change the screen resolution before starting Petrospace using the software utilities of the graphics driver (e.g. NVIDIA Control Panel, AMD/ATI Catalyst Control Center) or the System Settings of Windows. Please note that Petrospace requires at least 1204 x 768 pixels to operate correctly. It will run on lower resolutions, but you might not be able to use all functions in the menu mode. Jerky motion It is normal to experience short stops or jerky motion at the beginning of the simulation, especially when you look into a direction for the first time. This is because Petrospace must load graphics data into the graphics memory. You should not experience stops or jerky motion after this. If you experience jerky motion permanently, it is likely that the PC on which you are running Petrospace is not powerful enough for the simulation. Flashes/Missing background textures If you experience flashing surfaces or a black background instead of a sky and refinery panorama, it s likely that the graphics card of the PC on which you are running Petrospace lacks sufficient graphics memory. Try switching to a lower screen resolution (note that 1024 x 768 is the lowest recommended resolution for Petrospace) or install Petrospace on a different PC. You will need at least 128MB of graphics memory to run Petrospace in a resolution of 1024 x 768 pixels. The application is frozen and will not react to any mouse or keyboard input In rare cases Petrospace might freeze. This is most likely because of limited resources on your PC or because the PC is not powerful enough to run Petrospace. In this case you will need to hold down the keys Cntrl+Alt+Del at the same time to start the Process Monitor of Windows where you can click on Petrospace and select Kill process. You can also try pressing Alt+Tab to switch to the console window of Petrospace and close this window. Please close all applications running on your PC before starting Petrospace the next time. Missing pipe bends or small details If small details or pipe bends (in the distance) will not show, it means that your PC (i.e. your graphics card) is not powerful enough to display all details at the same time. In this case Petrospace will discard small features and details (e.g. parts of pipes in the distance) to try to enable a smooth operation. If you get closer to an object it will display correctly. You may try to switch to a lower screen resolution to avoid this effect. No sound 75

76 Please check that sound isn t turned off in the Windows Control Panel and check if you can hear standard systems sounds. If only Petrospace is silent, then you can try the following: 1. Go to the Petrospace install directory (e.g. C:\Program Files\Phenomatics\Petrospace ) 2. Go into the subdirectory bin and further into config 3. Locate the file bonfire.cfg and open it in the Windows Notepad 4. Locate the line sound_device "Generic Hardware" 5. Put two slashes at the beginning of this line so that it reads //sound_device "Generic Hardware" 6. Locate the line //sound_device "Generic Software" 7. Remove the two slashes so that it reads sound_device "Generic Software" 8. Start Petrospace 76
