Supercritical Calorimetry: An Emerging Field

open access: yesCHIMIA, 2002
Calorimetry (adiabatic, isothermal, differential, oscillating or acoustic) is generally based on heat-flow measurements of the studied system. Most of its applications are dedicated to kinetic-parameter determination, safety studies and process ...

Supercritical Carbon Dioxide Extraction

open access: yes, 2019
The objective of this thesis is to explore the properties of supercritical carbon dioxide (CO2). In addition, the feasibility of building a small-scale low cost system will be explained. A supercritical fluid is a fluid which exhibits properties between liquid and gas with liquid like densities and viscosities similar to a gas.
