The stream SEP is the outlet flow of the ethylene production unit, composed by ethylene and other undesired components. This stream flows into the heat exchanger (EX5) to be cooled down from around 117 °C–50 °C. The following valve (VA1) brings the SEP2 stream pressure to 39.51 bar, to be successively fed into the flash separator (FL1).
