# Fortis BC SCC

FluidFlow includes a script which allows staff at Fortis BC to create a Station Capacity Chart (SCC). Prior to plotting the chart, the user must set the gas regulators to solve using either the ISA equation or Universal Equation. This can be completed by selecting: Database | Gas Regulators. This will open a new dialog titled: "Database Editor - Gas Only Equipment" (see Figure 1). Select the appropriate regulator from the list on the left hand side. This will then display the relevant product data on the right hand side. Click on the field titled Regulator Equation to switch between the ISA equation or Universal Equation. When you have selected the desired method, select OK. Figure 1: Gas Regulator Database. At this stage, you can now select the script icon at the top of the flowsheet toolbar (Figure 2). Select the option titled: "Generate Station Capacity Chart". Figure 2: Script Menu. This will open a new dialog where you can set the station inlet start and end pressure and also, the desired "Runs" you wish to simulate (Figure 3). Figure 3: Generate Station Capacity Chart Dialog. When you have completed the data entry, select "Run". The software will now automatically run through the simulation and when complete, export the SCC to Excel. It is recommended you don't attempt to complete other tasks within FluidFlow or Excel during this process. The software will export a detailed table of calculated results along with the chart. Figures 4 & 5 provides an overview of the data exported to excel. Figure 4: Station Capacity Table of Results. Figure 5: Station Capacity Chart.
