Calculate the threshold level below which the content of components above C3 in ethylene-rich gas is such that the gas does not contain liquid

Establish a design specification: the independent variable is the flow rate of component C3, while the dependent variable is the vapor fraction in the outlet stream = 1

Adding a controller under limited conditions can solve this problem; this was the initial idea

In Flowsheeting Options->Design Specs, create a new design specification; the independent variable is the flow rate of component C3, and the dependent variable is the vapor fraction of the outlet stream, which should be equal to 1
