In this work, a simulation package to study the adsorption separation of main components biogas (CO2/CH4/N2) regarding its upgrading has been developed. Biogas is renewable source energy that can be produced by treatment agricultural, municipal, and industrial wastes. To obtain pure biomethane, needs upgraded (by removing CO2 N2). After that, biomethane either injected into natural gas networks...

The separation of alkanes, particularly monobranched and dibranched isomers, is paramount importance in the petrochemical industry for optimizing feedstock ethylene production as well upgrading octane number gasoline. Here, we report full linear/monobranched alkanes from their isomers by a robust easily scalable metal-organic framework material, Co3(HCOO)6. compound completely excludes but adso...

In drinking water, high concentrations of fluoride and arsenic can have adverse effects on human health. Waste deriving from the rice industry (rice husk, straw, bran) be promising adsorbent materials, because they are (i) produced in large quantities many parts world, (ii) recoverable a circular economy perspective, (iii) at low cost if compared to expensive conventional activated carbon, (iv)...

We describe a new approach to calculate the binding of flexible peptides and unfolded proteins to multicomponent lipid membranes. The method is based on the transfer matrix formalism of statistical mechanics recently described as a systematic tool to study DNA-protein-drug binding in gene regulation. Using the energies of interaction of the individual polymer segments with different membrane li...

The effect of isotherm parameters of a displacer on the efficiency of desorption Chromatography has been investigated numerically. A general nonlinear multicomponent rate equation model with Langmuir isotherm was used in this study. It was found that the best displacer in this kind of operation is usually not the one that is more strongly adsorbed than the adsorbates when the operation is to di...

Pressure Swing Adsorption (PSA) is one of the implemented technologies for removing carbon dioxide in biogas streams. Different adsorbents, mostly zeolite-based, and process configurations have been patented commercially demonstrated. In this study, we developed a numerical model to successfully describe dynamic performance biomass-derived activated purification. It first step designing biomass...

Complex colloidal fluids, such as emulsions stabilized by particles with complex shapes, play an important role in many industrial applications. However, understanding their physics requires a study at sufficiently large length scales while still resolving the microscopic structure of a large number of particles and of the local hydrodynamics. Due to its high degree of locality, the lattice Bol...

The diffusion of charged proteins in liquid-filled nanometer-sized apertures with charged surfaces has been investigated with fluorescence correlation spectroscopy (FCS). Based on a two-dimensional (2D) multicomponent diffusion model, key parameters such as the number of molecules diffusing freely inside the nanochannel or interacting with the surfaces, together with the specific diffusion para...

This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions are applied to the model with the Guo scheme for the external body force (i.e., the pressure gradient...

Cells sense spatial distributions of molecules which trigger signal transduction pathways that induce the cell to migrate or extend by remodelling the cytoskeleton. However, the influence of local and small variations of extracellular protein concentration on chemotaxis is not fully understood, due in part to the lack of simple and precise methods to pattern proteins in vitro. We recently devel...
