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 ...

Structural Properties of Yukawa One‐Component Plasmas Revisited

Contributions to Plasma Physics, EarlyView.
ABSTRACTYukawa one‐component plasmas are fully described in terms of the Coulomb coupling parameter Γ$$ \Gamma $$ and the screening parameter κ$$ \kappa $$. One of their remarkable properties is the existence of lines of constant effective coupling, Γeff(Γ,κ)$$ {\Gamma}_{\mathrm{eff}}\left(\Gamma, \kappa \right) $$, along which their short‐range ...

The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Determination of chain conformation of polysaccharides using a SEC‐MALLS‐Vis

Food Biomacromolecules, EarlyView.
Abstract For polysaccharides, biological activity is associated with the chemical structure as well as the chain conformation. The chain conformation is conventionally derived from the scaling relationships between weight‐average molecular weight (Mw) and intrinsic viscosity ([η]) or the radius of gyration (Rg) or the translational diffusion ...

On the relation between virial coefficients and the close-packing of hard disks and hard spheres

, 2011
The question of whether the known virial coefficients are enough to determine the packing fraction $\eta_\infty$ at which the fluid equation of state of a hard-sphere fluid diverges is addressed.

Phase Transition in Hot Pion Matter [PDF]

, 2000
The equation of state for the pion gas is analyzed within the third virial approximation. The second virial coefficient is found from the pion-pion- scattering data, while the third one is considered as a free parameter.

Virial equation of state for a granular system

The European Physical Journal E
The equation of state for an ideal gas is simple, which is $P=nk_{\rm B}T$. In the case of imperfect gases where mutual interactions among the constituents are important, pressure $P$ can be expressed as the series expansion of density $n$ with appropriate coefficients, known as virial coefficients $B_m$.

Computational Mechanics Model to Evaluate the Structural Maintenance of Catenated Hydrogen‐Bonded Organic Frameworks

Small, EarlyView.
This study presents a computational framework treating crystalline HOFs as adaptive atomic‐scale interfaces. Catenated HOFs preserve lattice stability under load while enabling auxetic deformation and reversible nonlinearity. The results provide direct evidence that supramolecular interactions govern macroscopic resilience and structural adaptability ...

The Virial Equation of State of Low-Density Neutron Matter

, 2005
We present a model-independent description of low-density neutron matter based on the virial expansion. The virial equation of state provides a benchmark for all nuclear equations of state at densities and temperatures where the interparticle separation ...

QCD equation of state in a virial expansion [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2009
We describe recent three-flavor QCD lattice data for the pressure, speed of soun d and interaction measure at nonzero temperature and vanishing chemical potentia l within a virial expansion. For the deconfined phase we use a phenomenological model which includes non-pert urbative effects from dimension two gluon condensates that reproduce the free en ...
