Separations of mixtures play a critical role in chemical industries. Over the last century, the knowledge in the area of chemical thermodynamics and modeling of separation processes has been substantially expanded. Since the models are still not completely accurate, hybrid models can be used as an alternative that allows to retain existing knowledge and augment it using data. This paper explores some of the weaknesses in the current knowledge in separations design, simulation, optimization, and operation, and presents many examples where data-driven and hybrid models have been used to facilitate these tasks.

Mixed Matrix Membranes (MMMs) which consist of 0.3 wt.% Zeolite-Carbon Composite (ZCC) dispersed in BTDA-TDI/MDI (P84 co-polyimide) have been prepared through phase inversion method by using N-methyl-2-pyrrolidone (NMP) as a solvent. Membranes were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Thermogravimetric Analysis (TGA), and Fourier Transform Infrared (FTIR). Membrane performance was measured by a single gas permeation of CO2 and CH4. The maximum permeability of CO2 and CH4, which up to 12.67 and 6.03 Barrer, respectively. P84/ZCC mixed matrix membrane also showed a great enhancement in ideal selectivity of CO2/CH4 2.10 compared to the pure P84 co-polyimide membrane.

“…To obtain porous carbon materials with excellent gas separation performance, it is critical to choose suitable carbon precursors for pyrolysis. Liu et al prepared a series of CMS by pyrolyzing cation exchange resins based on sulfonated poly(styrene‐co‐divinylbenzene). It was found that the pyrolysis peak temperature has a profound effect on the effective pore size and micropore volume of the CMS adsorbents.…”

As primary feedstocks in the petrochemical industry, light olefins such as ethylene and propylene are mainly obtained from steam cracking of naphtha and short chain alkanes (ethane and propane). Due to their similar physical properties, the separations of olefins and paraffins—pivotal processes to meet the olefin purity requirement of downstream processing—are typically performed by highly energy‐intensive cryogenic distillation at low temperatures and high pressures. To reduce the energy input and save costs, adsorptive olefin/paraffin separations have been proposed as promising techniques to complement or even replace cryogenic distillation, and growing efforts have been devoted to developing advanced adsorbents to fulfill this challenging task. In this Review, a holistic view of olefin/paraffin separations is first provided by summarizing how different processes have been established to leverage the differences between olefins and paraffins for effective separations. Subsequently, recent advances in the development of porous materials for adsorptive olefin/paraffin separations are highlighted with an emphasis on different separation mechanisms. Last, a perspective on possible directions to push the limit of the research in this field is presented.
