“…For the top product stream, the maximum allowable content of carbon dioxide is 2 mol %. 7,24 From regulation, the maximum allowable content of H 2 S in pipeline-quality gas is 4 ppm. 25 Since in this work hydrogen sulfide has been considered representative of all the sulfur species, for the case studies its limiting value in the produced gas has been considered 10 ppm, the maximum allowable value for personnel protection.…”

An energy and economic analysis on a new distillation process for the upgrading of high-CO 2 content natural gas streams has been carried out. The process has been optimized by means of a feed splitting technique to minimize the energy requirements. The performances of the process have been compared to the ones of a traditional MDEA scrubbing process in terms of energy expenses. The cost of energy has been quantified to build up a merit index function, which allows one to determine the trade-off between the two technologies as a function of the CO 2 and H 2 S content in the feed gas and the geographic area where the gas reserve is located. The results have been discussed on the basis of the cost of energy in different geographic areas, showing the benefits (in terms of energy and operating costs savings) of a low-temperature distillation process when the CO 2 content in the natural gas streams is high.

“…While removal of CO 2 from natural gas reservoirs is a matured technology and extensively studied 102 , the phenomena of separating CO 2 from waste production is relatively new, and is motivated by geopolitical efforts to reduce greenhouse gas production from major industrial contributors such as coal-fired power plants 103,104 . In this field, nanoporous materials could replace the incumbent technology, aqueous amines 105 , by reducing the energetic costs to captureregeneration cycles, while eliminating some of its undesirable side effects, such as the corrosive nature of the carbamate species formed from a chemical bond between amines and CO 2 .…”

H1 Abstract.There is currently a large push towards big data and data mining in materials research to accelerate discovery. Zeolites, metal-organic frameworks (MOFs) and other related crystalline porous materials are not immune to this recent phenomenon, as evidenced by the proliferation of porous structure databases and computational gas adsorption screening studies over the past decade. The strive to identify the best materials for a variety of gas separation and storage applications has not only led to collections of thousands of synthesised structures, but the development of hypothetical material building algorithms.The materials databases assembled with these algorithms expand greatly on the range of complex pore structures that have been synthesised, with the rationale that we have discovered only a small fraction of realisable structures and expanding upon these will accelerate rational design. In this review, we highlight some of the methods developed to build these databases, and some of the important outcomes resulting from large-scale computational screening efforts. SummaryIn the field of nanoporous materials discovery, we are witnessing the emergence of big data analytics combined with traditional computational thermodynamics calculations. This review turns a critical eye on the current state of the art, with a focus on computational database generation and results from large-scale screening for gas separations. H1 Introduction.The discovery, in the late 19 th century, that zeolites could trap interesting and valuable particles in their pores opened up an entire field of research 1,2 . This seemingly simple phenomenon was an enormous boon to the oil and gas industry, seeing as how cheap, but effective porous materials could serve as a catalyst for hydrocarbon cracking. From their humble beginnings (being carved out of rock faces), zeolites, and their ability to selectively trap guests in their pores, have become integral in not only the oil and gas industry, but in detergents (as ion exchangers) and natural gas purification to name a few 1 .Zeolites have since enjoyed an almost exclusive dominance in porous materials research until the late 20 th century, when we began to observe the creation of more diverse materials in terms of chemistry, network connectivity, and physical properties.At present, there are a little over 200 known zeolite structures, which is only a small fraction of the total number of structures that have been predicted 3 . In addition, if we were also able to expand the chemical diversity of these materials beyond the conventional Si 4+ , O 2-, and Al 3+ ions found in zeolites, one could envision designing materials for virtually any gas separation application. Thus when the first articles arose in the 1990's characterising Metal-Organic Frameworks (MOFs) [4][5][6][7][8] , and later Covalent Organic Frameworks (COFs) 9,10 , Zeolitic Imidazolate Frameworks (ZIFs) 11 , and Porous Polymer Networks (PPNs) 12 the excitement was palpable. It was recognised early-on by Yaghi, O'Keeffe, ...

“…As CO 2 has no energy value by itself, its presence in natural gas streams lowers the energy content (calorific value) of natural gas. It also contributes to pipeline and equipment corrosion during storage and transportation [4]. The removal of carbon dioxide from those gases has been carried out by means of several technologies, such as absorption, cryogenic distillation, membrane separation, and adsorption.…”
