“…Alumina has better resistance to liquid water, so a thin layer is put in first place to contact the wet NG. This ordering supports the lifetime of the molecular sieve, which is placed below the alumina layer [26].…”

One of the most severe problems affecting the efficient operations of gas pipelines is corrosion caused by black powder. According to the literature, the primary source for the existence of black powder is condensed water. In this case study, the temperature (40˚C) of the sales gas is much higher than its dew point (9.24˚C). The water is therefore in vapor phase. It is then proposed to remove water vapor from the gas at the entrance of the plant using an adsorption process. The recommended technology is the Layered Bed Temperature-Swing Adsorption (LBTSA) with micro-channels with molecular sieve zeolite 4A and activated alumina as adsorbents. In the case of presence of aerosols that could condense water, it is suggested to utilize a RED (Rare Earth Drum) magnetic separator in order to remove black powder from the gaseous feed.

“…However, in the case of the production of liquefied natural gas, it is necessary to reduce the water content to about 1 ppmv in order to avoid the formation of hydrates during the cryogenic separation of heavier hydrocarbons. Since there is this limiting condition, the usage of zeolite adsorption is the most suitable method [51,52]. This part was not directly modeled in the Aspen HYSYS.…”

There is a global need to increase the production of alternative sources of energy due to many issues related to conventional sources, such as environmental degradation or energy security. In this paper, decentralized liquefied natural gas production is analyzed. Liquefied natural gas, according to the analysis, can be considered a viable alternative even for decentralized applications Design and economic analysis of a small-scale biogas LNG plan together with the necessary technology and economic evaluation are presented in the paper. The results show that a project of the proposed size (EUR 3 million) offers a relatively good profitability level. Specifically, the net present value of the project is mostly positive (around EUR 0.1 million up to EUR 0.8 million). Therefore, based on the research, small LNG plants operating across the continent can be recommended for the processing of local sources of biogas.

Es wurde ein Verfahren entwickelt, das die Umwandlung von Reststoffen zu methanbasierten Kraftstoffen unter höchstmöglichem Erhalt des biogenen Kohlenstoffs mithilfe von elektrischer Energie aus erneuerbaren Quellen ermöglicht. Waldrestholz, Stroh und Klärschlamm wurden als besonders relevante Einsatzstoffe identifiziert. Durch die hochintegrierte Kopplung von Vergasung, Hochtemperaturelektrolyse und Methanisierung wird der biogene Kohlenstoff aus den Edukten nahezu vollständig in das Produkt Methan überführt. Die Gestehungskosten sind dabei mit denen gegenwärtig eingesetzter Technologien vergleichbar und liegen bei Großanlagen im Bereich üblicher Werte der Biomethanerzeugung.A highly integrated process for the conversion of biogenic residues in combination with electricity from renewable sources to methane-based fuels was developed. Forest residues, straw and sewage sludge were identified as particularly relevant input feedstock. By combining gasification, high-temperature electrolysis and catalytic methanation, the biogenic carbon remains almost completely in the products. The matching temperature levels of the heat streams result in a very efficient process. The production costs are comparable to less resource-saving technologies and predictably lower than those of biomethane when plant capacities are increased.
