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 will discuss 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.
We will discuss the three primary operating objectives of fractionation facilities:
1. Meet product specifications
2. Keep operating costs at a minimum
3. Maximize stable production / profitability
Discuss liquid product specifications and why they are important
Describe multicomponent phase behavior
Explain why phase behavior is the key to understanding fractionation column operation
Understand how stabilizers / fractionation columns work
List the purpose for the condenser, reboiler and external reflux
Describe what controls column pressure and bottoms operating temperature
What Will Attendees Learn?
Typical liquid product specifications
How fractionation columns separate the key components into a distillate and bottoms product stream
The primary column control points
Understand how reflux ratio controls the overhead product composition
Discuss why lowering the column operating pressure is an opportunity in reboiler (fuel gas) savings
Who Should Attend?
This webinar is directed towards Supervisors, Operators, and Facilities Engineers working in facilities that have fractionation trains associated with their operations. The seminar will also benefit anyone who wishes to update themselves on the primary operating principles of fractionation columns and phase behaviour.
