This section of the Quality Guidelines provides recommended impurity limits for CO 2 stream components for use in conceptual studies of CO 2 carbon capture, utilization, and storage systems. These limits were developed from information consolidated from numerous studies and are presented by component and application. Impurity levels are provided for carbon steel pipelines, sequestration through enhanced oil recovery (EOR), saline aquifer sequestration (SAS), and co sequestration of CO 2 and H 2 S in saline reservoirs. This guideline is intended only for conceptual studies under a generic scenario and should not be used for actual projects, which are likely to have requirements that differ from the generic scenario assumed herein. Exhibit 2-1 contains the recommended limits for CO 2 stream impurities required by the transportation pipeline, by EOR applications, and by saline reservoirs. Each of the three design cases presents a design point and a range independent of the other design cases. For most impurities, the range indicates the maximum and minimum values found in the literature review and does not necessarily represent recommended limits; however, some represent an unofficial industry standard or the lack of information. In most cases, the design value matches the most restrictive constraint. Details for the design value and range for each impurity can be found in the subsections below the table. An extensive literature search revealed there is little experimental work done to date to identify the corrosion mechanisms that set the limitations on most of the impurities listed below. Corrosion testing is difficult because of the multiple variables involved but is critical to determine standards for corrosion levels.
