CO2 capture using liquid crystals: Selectivity analysis for CO2 capture from syngas

The current need to reduce CO2 emission from power plant flue gas demands development of new and more energy efficient separation processes. Liquid crystals are a new class of solvents for CO2 absorption; making use of a solubility switch between two phases. Solubility of CO2 is higher in the isotropic liquid phase than in the structured liquid...

Sensitivity analysis of residential building simulations: Model choice for specific applications and critical parameters

Sensitivity analysis of a residential building. To observe critical parameters that influence the building energy behaviour.

Predicting the diffusivity of CO2 in substituted amines

The experimental determination of the diffusivity of carbon dioxide (CO2) in an amine solvent is difficult as the CO2 diffuses and reacts simultaneously when absorbed into an amine solvent. As the knowledge of the diffusivity and solubility of CO2 is essential to design the absorption units based on amine solvents, the nitrous oxide (N2O)...

Experimental Validation of a New Ammonia/Water Absorption Model in a Minichannel Annulus

In this study two mathematical models are developed to evaluate the performance of ammonia/water absorption and desorption in a minichannel. The models evaluate pressure drop, heat transfer and mass transfer inside the minichannel, including the effect of surface tension and flow patterns.
