Abstract In order to evaluate chemical impacts of SO 2 impurity on reservoir rock during CO 2 capture and storage in deep saline aquifers, several batch reactor experiments were performed on laboratory scale using core rock samples from the pilot CO 2 injection site in Heletz. In this experiment, the samples were exposed to pure N 2 (g), pure CO 2 (g), and CO 2 (g) with an impurity of 1.5% SO 2 (g) under reservoir conditions for pressure and temperature (14.5 MPa, 60 °C). Based on the set-up and...

Abstract Potential effects of SO2 as an impurity on CO2 injectivity for CO2 storage in a targeted sandstone saline aquifer in western Canada were investigated. Batch experiments using rock and brine samples in contact with supercritical CO2 and CO2 mixtures with SO2 were conducted in high-pressure reactors for 45 days. The results suggest that SO2 increased precipitation of sodium chloride and calcium sulfate dehydrate, and also increased the dissolution of quartz. Moreover, the precipitation of...

This paper provides an overview of the aims, objectives and the main findings of the CO2QUEST FP7 collaborative project, funded by the European Commission and designed to address the fundamentally important and urgent issues regarding the impact of the typical impurities in CO2 streams captured from fossil fuel power plants and other CO2 intensive industries on their safe and economic pipeline transportation and storage. The main features and results recorded from some of the unique test facilit...

The ultimate composition of the CO2 stream captured from fossil fuel power plants or other CO2 intensive industries and transported to a storage site using high pressure pipelines will be governed by safety, environmental and economic considerations. So far, most of the studies performed on this topic have been limited in scope, primarily focusing on investigating the impact of the CO2 stream impurities on each part of the Carbon Capture and Sequestration (CCS) chain in isolation. This is a sign...

Abstract In the area underlain by the Basal Aquifer in the Prairie region of Canada, there are 20 large CO 2 sources (coal-fired power plants, oil sands and heavy oil production and upgraders, refineries, chemical and petrochemical plants, fertilizer plants and cement plants) that emit more than 1 Mt CO2/year each, for a total of 83 Mt CO 2 /year,which represents 12% of canada ‘s anual greenhouse gas emissions. If post-combustion capture technologies are used, 75 Gt CO 2 /year can be captured fr...

Abstract Carbon capture and storage (CCS) is one of the major transformative technologies for reducing atmospheric CO 2 emissions from large CO 2 emitters where a large potential for geological CO 2 storage exists. CO 2 captured from the emitters contains various impurities, such as N 2 , O 2 , Ar, SO x , etc., and allowing these impurities to be stored together with CO 2 would reduce the cost of CO 2 capture. However, the impurities would have various undesirable effects on CO 2 storage. In thi...
