Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Lyman Alpha Emitting Galaxies as a Probe of Reionization [PDF]
, 2014 The Epoch of Reionization (EoR) represents a milestone in the evolution of our Universe. Star-forming galaxies that existed during the EoR likely emitted a significant fraction (~5-40%) of their bolometric luminosity as Lyman Alpha (Lya) line emission ...
