Case 14236

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

Keywords:

Carbon-dioxide Purification, NOx and SOx gases, CO2

Applications:

Purify Oxy fuel combustion flue gases.

Problem:

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

Technology:

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.

Advantages:

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