The main objective of this paper is to examine the effect of nanomaterials on mass transfer coefficient in bubble type absorption of carbon dioxide by experiment. The absorption process is carried out in a bubble column and in room temperature. Mass transfer coefficient, saturated concentration of CO2, and gas holdup are determined in this system. The kinds of nanomaterials, the concentrations ...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

Introduction To predict the evolution of a Geological Disposal Facility, it is necessary to understand the interaction between a number of key features and process and its impact on the long-term behaviour. Central to these issues are the mechanisms and process that govern the movement of gases in a repository. Linking the gas transport to the stress-strain response of the engineering systems b...

We report on a gas phase process to synthesize and integrate seed particles and inorganic nanowires with control over location, diameter, length, and geometrical orientation. The process flow begins with the gas phase synthesis and size selection of nanoparticle seeds. The seed particles are deposited onto addressable locations on a substrate by Coulomb force and fringing field directed assembl...

arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...
