Prediction of thermodynamic properties: centerpiece approach—how do we avoid confusion and get reliable results?

The absolute vapor pressures of three amino-alcohols were measured using the transpiration method. The consistent set of standard molar enthalpies of vaporization for eighteen amino-alcohols was evaluated using empirical and structure–property correlations. The averaged values of vaporization enthalpies were recommended as reliable benchmark properties for the heat management of CO2 capture technologies. Centerpiece approach based on the group-additivity principles was developed toward amino-alcohols. Graphic abstract

Water budgets for natural systems

Natural systems including constructed and natural wetlands as well as irrigated land areas,geofilters and ponds are capable of absorbing pollutant loadings, and in appropriatecircumstances can provide a low cost alternative to traditional chemical and biologicaltreatment. Many projects have shown reduction of nutrients, oxygen consuming substancesbut also more environmental haz.ardous compounds.Natural systems seem to have a great potential for treatment of leachate. Some parts of thesesystems belongs to biological treatment and other parts to "filtration" and therefore thesesystems could be seen as a mix of transformation and filtration together with the volumereducing effect by evaporation and transpiration. Method used in Sweden are mainly SoilPlant (SP) system there a large part of the treatment is removal of water by evapotranspiration.Irrigation of e.g. energy forest or land surfaces increases the possibility of natural evaporation.When an area of the landfill is irrigated the water balance will change. This paper focusesupon the water budget and water movement within the natural system.
