Abstract
Processes and systems for analyzing a composition of a C3− component separated from a steam cracker effluent. The process can include steam cracking a hydrocarbon feed to produce a steam cracker effluent. The effluent can be cooled to produce a cooled effluent and a sample can be separated therefrom. Heat can be indirectly exchanged from the sample to a heat transfer medium to produce a gas phase product that can include C3− compounds and a first liquid phase product that can include C4+ compounds. The gas phase product can flow through a flow restricting line and into a transport line. The flow restricting line can have an inner cross-sectional area that is <50% of an inner cross-sectional area of the transport line. The gas phase product can flow through the transport line and into an analyzer. An at least partial composition of the gas phase product can be determined.
