TL;DR: In this article, the fugacity of CH4 from CH4-hydrate soaked in liquid CO2 was measured at 274-277 K and 4-5 MPa, while that of CO 2 was much higher than the initial forming fugacity.

TL;DR: A gas separation process is a unit therefor. as discussed by the authors describes the steps of: introducing a gas consisting of two or more components into an adsorption system in which adsorbent particles circulate in a fluidized state, thereby to allow, at atmospheric pressure or an elevated pressure, the adsorbents to adsorb a gas component to be separated from the gas.

TL;DR: Citric acid (CA) has successfully been separated from fermentation broth by a novel and unique purification process, which is characterized by organic solvent extraction and precipitation with compressed carbon dioxide (CO 2 ) as a poor solvent as discussed by the authors.

TL;DR: An empirical mixing rule for the Helmholtz function with ternary as well as binary non-randomness parameters was proposed based on the density-dependent local composition concept in this paper, which successfully correlated the phase equilibria of the carbon dioxide-ethanol-water system.

TL;DR: In this paper, a combination of hydrovisbreaking and hydroconversion by asphaltene bottom cracking (ABC) catalyst was used for cracking of inferior crudes with a high metal content.
