The gas processing simulation will be built using the following basic steps:
1. Create a unit set.
2. Choose a property package.
3. Select the components.
4. Create and specify the feed streams.
5. Install and define the unit operations prior to the column.
6. Install and define the column.In this Tutorial, a natural gas stream containing N2, CO2, and C1 through n-C4 is processed in a refrigeration system to remove the heavier hydrocarbons.

The lean, dry gas produced will meet a pipeline hydrocarbon dew point specification. The liquids removed from the rich gas are processed in a depropanizer column, yielding a liquid product with a specified propane content.

The following pages will guide you through building a UniSim Design case to illustrate the complete construction of the simulation, from selecting a property package and components to examining the final results. The tools available in the UniSim Design interface will be utilized to illustrate the flexibility available to you.
