the subject we discussion about are nucleation and meta stable phenomena’s , superheat liquids , supercold liquids and meanwhile  applications of this liquids. all in all meta stable situation can occur in three condition: first while changing liquid phase to gas phase by heating , second changing liquid phase to solid phase by cooling , third while moving water stream in subsonic nozzles or su...

We review the scientific history of random close packing (RCP) of equal spheres, advocated by J D Bernal as a more plausible alternative to the non-ideal gas or imperfect crystal as a structural model of simple liquids. After decades of neglect, computer experiments are revealing a central role for RCP in the theory of liquids. These demonstrate that the RCP amorphous state of hard spheres can ...

Production of low-viscosity liquids (including condensates) from tight reservoirs (such as shales) is severely restricted by the ultra low-permeability of such formations, limiting production to a very small fraction (usually less than 5 percent) of the liquids-in-place. In this study, which is part of a wider investigation, we evaluate by means of numerical simulation several possible strategi...

natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

Ionic liquids can be used as solvents for gas absorption operations in order to improve the process economy and general efficiency of gas separations. This work investigates solvent properties of ionic liquids and compares them to amine solutions used for absorption of carbon dioxide (CO2). The CO2 solubility into imidazolium-based Room Temperature Ionic Liquids (RTILs) was measured at temperat...
