The transport sector is one of the largest emitters of climate-effecting emissions. Thus, a major transformation in this sector is necessary to achieve Germanys and EUs ambitious goals of CO2 neutrality. In these transitions, fossil fuel-based engines will be replaced by sustainable ... En savoir plus
High power CO2 lasers have been the workhorses for sheet metal cutting, welding and many more applications in materials processing during the past decades. Even though a significant replacement by fiber coupled lasers takes place, there are still many applications that benefit from the ... En savoir plus
Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... En savoir plus
Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... En savoir plus
Carbon dioxide levels are increasing faster than in hundreds of thousands of years due to fossil fuels burning. A serious worldwide interest is growing towards the field of CO2 valorization as a step in transitioning away from fossil fuel economy at the same time of decreasing CO2 ... En savoir plus
Photosynthesis can be defined as the conversion of solar energy into chemical energy. In green plants, this applies to the conversion of CO2 into organic compounds. The energy stored in these compounds can later be used to supply energy to run physical and chemical processes in plant ... En savoir plus
In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... En savoir plus
The primary interest of the VC (Vacuum Characterization) test is to experimentally characterize the adsorption and vacuum desorption of CO2 and water vapor of a pelletized sorbent bed in a large diameter column. The VC test article is shown in Figures 1 and 2. The aluminum canister is 3” ... En savoir plus
This work encompasses different physics involved in fluid flow in shale gas reservoir. Non-linear equations for fluid flow are solved with COMSOL Multiphysics® PDE module. It focuses on comparing the performance of various species transport flux models by accounting for inter-molecular ... En savoir plus
The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. In general, four ... En savoir plus
