Case 14236

A Novel Approach to Carbon-dioxide Purification for Oxy-Combustion System


Carbon-dioxide Purification, NOx and SOx gases, CO2


Purify Oxy fuel combustion flue gases.


Reservoirs to store recovered CO2 cannot tolerate specific contaminants above threshold concentrations.


This invention proposes a CO2 purification process consists of three major sections:

  1. The NOx and SOx removal unit
  2. The non-condensable gas removal unit
  3. The CO2pressurization unit. Each of these systems is designed and described in detail.


Achieve purity requirements for oxy-combustion systems over a wide range of constraints.
