2. 1. Property Impacts on Heat Exchanger Design in CO2 Cryogenic Process of Carbon Capture and Storage

   Author : Yuting Tan; Jinyue Yan; Hailong Li; Bin Liang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Literature review; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; sizing design; property impact; viscosity; thermal conductivity; property model; Energy Technology; Energiteknik;

   Abstract : Carbon capture and storage (CCS) is one of the most promising technologies which can significantly reduce CO2 emissions. A better understanding of thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. READ MORE

4. 2. CO2 storage in deep saline aquifers : Models for geological heterogeneity and large domains

   Author : Liang Tian; Auli Niemi; Fritjof Fagerlund; Simon Mathias; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2; Carbon Capture Storage; Storage Capacity; Injectivity; Monte Carlo; Gaussian; Permeability; Upscaling; 二氧化碳; 地質封存; 高斯仿真; 滲透係數; 非均質性; 升尺度; 存儲效能; 場地模擬; 不確定性; 壓力累積;

   Abstract : This work presents model development and model analyses of CO2 storage in deep saline aquifers. The goal has been two-fold, firstly to develop models and address the system behaviour under geological heterogeneity, second to tackle the issues related to problem scale as modelling of the CO2 storage systems can become prohibitively complex when large systems are considered.

   Abstract : Carbon capture and storage (CCS) is one of the most promising technologies that may significantly reduce CO2 emissions. A better understanding of the thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. READ MORE

6. 4. Off-gassing from thermally treated lignocellulosic biomass

   Author : Eleonora Borén; Markus Broström; Sylvia H. Larsson; Peter Björklund; Lorenz Gerber; Henrik Antti; Capucine Dupont; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; steam explosion; enclosed storage; CO; CO2; O2 depletion; VOCs; Tenax-TA; SPME; process settings; storage temperature; storage time;

   Abstract : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. READ MORE

7. 5. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

   Author : Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

   Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. READ MORE
