CCUS for the Pulp and Paper Industry Webinars – Session 3 Video 1.
The following presentation discusses CO2 purification for the Pulp & Paper sector. The primary objective is to produce a purified CO2 stream that is suitable for transportation and/or utilization in an effort to achieve net-zero or negative emissions. The presentation considers and discusses the pros and cons of a variety of flue gas treatment, CO2 capture, and compression/liquefaction options for the major CO2-containing streams in a typical kraft mill. Key observations on post-combustion CO2 capture and purification approaches are discussed, including alternative strategies, such as flue gas stream blending and oxy-firing, to lower costs and improve capture efficiencies. Major knowledge gaps are defined to deploy CO2 capture and purification systems, including potential next steps using models and machine learning tools (TEA and LCA) being developed as part of the National CCUS Assessment Framework.
