Abstract
Carbon capture and storage has gained increased attention during the last decade, and several full-scale projects are currently being planned. From economic and public acceptance point of view it is important to ensure that the transportation system is operated in a safe manner, avoiding threats such as corrosion or formation of solid matters. Thus, routine chemical analyses are required to ensure that the CO2 stream complies with the required specifications. The CO2 will usually be transported in the liquid or supercritical state (high pressure), which makes the practicalities around chemical analyses difficult. Phase transition from liquid or supercritical state to gaseous state may also introduce several physiochemical effects that may affect the analyses. This paper discusses technical and practical challenges with CO2 stream analyses experienced in a joint industry project that studied corrosion and chemical reactions in a simulated CO2 transport system.
Highlights
Carbon capture and storage (CCS) has gained increased attention as a method to reduce emissions of anthropogenic CO2 to the atmosphere [1,2]
Since most CO2 transport specifications [14] are based on the concentration of impurities in the transport system, this paper focuses on the monitoring during transport or monitoring related to mixing of several CO2 streams
Most of the present work is based on the experience gained during the process of building a corrosion test system that can be operated under CCS conditions in our lab
Summary
Carbon capture and storage (CCS) has gained increased attention as a method to reduce emissions of anthropogenic CO2 to the atmosphere [1,2]. The acidic aqueous phase may introduce corrosion problems in the CO2 transportation system, a system which most likely will be constructed of carbon steel due to cost and availability [7,8]. Elemental sulphur is another possible reaction product [9,10]. Most of the present work is based on the experience gained during the process of building a corrosion test system that can be operated under CCS conditions in our lab. Chemical reactions, etc., are only briefly treated here, as more details can be found elsewhere [3,9,15]
