Objective In this workshop, you will build a turbo expander and NGL fractionation plant model. You will also use the LNG Exchanger unit operation to simulate a multi-pass heat exchanger. The liquids produced from the inlet hydrocarbons will feed into a fractionation section consisting of a pair of distillation columns for liquefied gas recovery. You will also review reporting in Aspen HYSYS by applying desired physical properties via the Correlation Manager. In this workshop, you will build the flowsheet that will be used throughout most of the modules of this course.
The process is a Turbo Expander plant where LPG Product is obtained from a feed natural gas stream by cooling, expanding, separating, and distilling the condensed liquids. The remaining gas is then re-compressed for export.
