Then select Stream to conect Flash with in and outputs arraws,after connecting press Ecs. First you need to select the piece(s) of equipment you desire, from All UnitOps tap select Feed arraw, two prodcut arraws and Flash #1. Select Format>Engineering Unit> Select default setting in English units. Step 2: Now select engineering units that you will use for your simulation. Select File>Save as, then name your simulation Flash Chamber.

Step 1: After you Start up Chemcad, start new simulation, how? What are the product compositions and flow rates? Feed conditions are the same as that of the flash chamber. Let start with a simple example to show how you can applied previous procedure.Ī flash chamber operating 80oC(176oF)and 500kPa (72.5 psia)is separating 1000 kg/hr (2204 lb/hr) of a feed that is 10 mol%Ethane, 5%Propane, 15% n-Butane, 10% n-Pentane,12% iso-Pentane, 8% n-Hexane, 30%Heptane and 10%Nonane. Creating flowsheets and running simulations is fast and easy with CHEMCAD, and the program is highly customizable to fit your needs and the way you work.īefore we start, should you know the basic procedure for creating a simulation that can be broken down into the following common steps:Ģ-Select engineering units for the simulation.Ĥ-Select chemical components for the process.ĥ-Select K‐value and enthalpy options for the process.Ħ-Define the feed streams used in the process.ħ-Enter specifications for the unit operations.
