this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

This article presents various gas separation membrane simulation techniques based on typical engineering and design for process description. Modelling processes are tasks that use different tools to simulate the profile of process. Given some initial data, such as flow, temperature, concentration pressure, correlations presented can be used perform simulations. After selecting flow configuratio...

Membrane technology is the most promising in post-combustion capture compared to absorption, adsorption and cryogenic distillation methods. It an advanced new for recovery of carbon dioxide. has several advantages when other methods due its’ simple process, low cost, lower footprint, sustainable environment energy saving method. The challenge fabrication method polymeric membrane, it depends on...

It is highly desirable to reduce the membrane thickness in order to maximize the throughput and break the trade-off limitation for membrane-based gas separation. Two-dimensional membranes composed of atomic-thick graphene or graphene oxide nanosheets have gas transport pathways that are at least three orders of magnitude higher than the membrane thickness, leading to reduced gas permeation flux...

One of the research directions renewable energy sources is production biohydrogen from dark fermentation organic matter. During this process, since hydrogen produced along with a complex mixture other gases and vapors, gas requires further purification. relatively easy solution to problem might be utilization separation membrane modules given their low consumption, simple operation ease upscali...

From water desalination and gas purification to metal recovery beyond, membrane separation has become integral numerous industrial applications [...]

An optimal design strategy for membrane networks separating multicomponent gas mixtures based on an approximate permeator model and mixed-integer nonlinear programming (MINLP) is proposed. A permeator system superstructure is used to embed a very large number of possible network configurations and allows the permeator feed-side pressure to be fixed or a design variable. A MINLP design model is ...
