1.1        This document specifies methods for measuring and evaluating the performance of CO2 capture connected to a CO2 intensive plant, and which separates CO2 from the CO2 intensive plant exhaust gas in preparation for subsequent transportation and geological storage. In particular, this document provides a common methodology to calculate key performance indicators (KPI) for the CO2 capture plant. To determine the KPIs, the boundaries of the CO2 capture plant need to be defined and the necessary parameters need to be measured.


1.2        This document covers the CO2 capture plant capturing CO2 from CO2 containing exhaust gas connected to CO2 intensive plants. The connection of a CO2 capture plant to a CO2 intensive plant is anticipated to have negligible impact on the product quality or the quantities produced by the CO2 intensive plant. This is in contrast with the integration of CO2 capture plants with power plants which usually results in a reduction of the power plant output. For the CO2 intensive industry, it is important that product quality remains the same after connection of the CO2 capture plant, in order for the industry to continue to meet customer requirements.


The CO2 capture technologies covered by this document are able to operate without interfering with the operations of the CO2 intensive plant. Frequently used CO2 capture technologies are chemical absorption (e.g. liquid amine) and solid adsorption [e.g. pressure swing adsorption (PSA), temperature swing adsorption (TSA)]. Other CO2 capture concepts are membranes, cryogenic and other capture technologies. The CO2 capture plant can be installed for treatment of the full volume of exhaust gas from the CO2 intensive plant or a fraction of the total (i.e. a slipstream). Captured CO2 is then conditioned, e.g. dried and compressed or liquefied, as de...
