TL;DR: Wang et al. as discussed by the authors analyzed the details of water consumption and water-saving potential for coal-to-synthetic natural gas process, and showed that combined heat and power plant, shift, air separation and clean-up respectively take 23.4, 21.9, 18.8% and 14.4% of total water consumption in the production process.

TL;DR: In this paper, the authors compare the impact of natural gas fuels and additives derived from natural gas and blended with gasoline with that of gasoline alone by examining the energy efficiency of the fuel cycle as well as greenhouse gas emissions.
Abstract: A careful analysis is needed of the energy efficiency of the fuel cycle (the efficiency of the conversion from resource extraction to final use by consumers) and the environmental impact of natural gas fuels. This information can help policy makers decide which fuels could be used to displace imported oil, maintain air quality, and be the basis of a new transportation fuels infrastructure. The authors compare the impact of natural gas fuels and additives derived from natural gas and blended with gasoline with that of gasoline alone by examining the energy efficiency of the fuel cycle as well as greenhouse gas emissions. Although this subject has been studied before, they add to those earlier studied by looking at MTBE, alkylate, and gasoline (from natural gas). The authors also reexamine CNG, LPG, and methanol on the basis of a vehicle's efficiency potential. Although LNG vehicles were included in an earlier study, they are not included here because lifecycle greenhouse gas emissions were found to be comparable to those from CNG vehicles. They compare natural gas fuels against a baseline fuel--nonoxygenated gasoline (hereafter referred to simply as baseline gasoline).

TL;DR: In this paper, the authors proposed a method for the recycling of industrial tail gases and particularly relates to a process of preparing synthetic natural gas by using yellow phosphorus tail gas. But this method is not suitable for industrial scale application and can only be used for high purity methane gas by taking the Yellow Phosphorus tail gas containing various impurities as fuel gases or chemical materials for users to use.
Abstract: The invention belongs to the field of resource recycling of industrial tail gases and particularly relates to a process of preparing synthetic natural gas by using yellow phosphorus tail gas. The process comprises the following steps: carrying out blowing and pressurization, pre-cleaning, desulfuration, pickling by concentrated sulfuric acid, alkali neutralization, pressurization, temperature swing adsorption purification, dearsenification, defluorination, deoxygenation, CO conversion, cooling and drying, decarbonization, superfine purification, methanation and cooling and drying on raw material yellow phosphorus tail gas, and thus finally preparing a natural gas product. The process provided by the invention is a yellow phosphorus tail gas purifying and synthetic natural gas preparing packaged technology suitable for industrial scale application and can prepare high purity methane gas by taking the yellow phosphorus tail gas containing various impurities as fuel gases or chemical materials for users to use.

TL;DR: In this paper, the authors implemented a tar condensation and re-vaporization sub-model in a previously established CFD model for the Entrained Slagging Transport Reactor (E-STR) gasifier, modified from the existing E-Gasifier simulation models in previous studies.
Abstract: The objective of this study is to implement a tar condensation and re-vaporization sub-model in a previously established Computational Fluid Dynamics (CFD) model for the Entrained Slagging Transport Reactor (E-STR) gasifier, modified from the existing E-Gasifier simulation models in previous studies. The major modifications in E-STR, compared to the existing E-GasTM design, include higher operating pressure and lower temperature, with the aim of achieving a higher H2/CO ratio of syngas, which is more favorable for synthetic natural gas (SNG) production. In this study, the aforementioned sub-model is described by the UDF (User-Defined Function) and incorporated in a previously developed computational model for entrained-flow gasification process, to study the syngas composition without implementing a tars-cracking catalyst in the E-STR gasifier. The results show that incorporating the tar condensation model leads to a formation of approximately 6.47% liquid volatiles and an exit temperature increase about 135 K, due to the release of latent heat. These sub-models have been successfully implemented and will be useful in the condition that the gasifier temperature is intentionally kept low, just as the E-STR gasifier. The results indicate that high pressure and less oxygen feed produce a higher H2/CO ratio, more favorable for SNG production.
