Fractionation: Understanding Your Column From First Principles

Fractionation is required to produce saleable liquid hydrocarbon products from extracted NGLs, often referred to as Y-grade in North America. This webinar discusses fractionation columns that separate the NGLs into the various liquid product commodities. The first step in understanding column operating parameters is to understand product specifications and how those specifications relate to the required column operating conditions. Understanding multicomponent distillate phase behaviour is the key to understanding what sets column operating pressure, and subsequently required reboiler temperature.
