Process design and simulation study: CO2 utilization through mixed reforming of methane for methanol synthesis

Biogas to Syngas through the Combined Steam/Dry Reforming Process: An Environmental Impact Assessment

“…After this first stage of the ATR process, the hot stream (6) passed through a second stage where the SR and WGS reactions took place. The resulting stream 8 was then sent to the series of two energy recovery steps previously described and, finally, collected (8c) to an expander (K-102) and cooled directly into the separator V-100 to separate the water (11) from the gaseous stream (10).…”

“…This gaseous stream can be produced by different reforming technologies that are nowadays exploited to convert natural gas in centralized and high production plants. 10 These processes represent the most energy-intensive step of the production chain 11 and can consequently greatly influence the impact of the overall gas-to-liquid system on the environment.…”

“…On the other hand, using a single tri-reforming reactor, its sustainability through better energy savings and flue gas utilization was assured. A mixed reforming of NG, CO 2 , and H 2 O to produce syngas for methanol synthesis was also investigated by Shi et al By feeding a small amount of CO 2 to the SR reactor (CO 2 /CH 4 = 0.29 v/v), the authors found that using the combined reforming, the methanol productivity increased but, because of the choice to use the purge gas stream as the main source of fuel for the reformer furnace, no improvements in terms of CO 2 emissions were achieved. Proceeding from these premises, the study aimed to investigate the industrial conditions needed to decrease the environmental impact of the S/DR process.…”

Sustainability-inspired upcycling of waste polyethylene terephthalate plastic into porous carbon for CO2 capture

“…Combined with experimental data, preliminary process designs could be further upscaled and optimized, thereby providing vital information (including energy and mass balance, thermodynamic efficiency, and carbon emissions) that can serve as a realistic basis for the analysis of the economic and environmental aspects. Process simulation has been used in various research areas such as oil and gas, 26 chemical synthesis, 27,28 biomass utilization, 29,30 and renewable energy. [31][32][33] This approach was best exemplified in a feasibility study on solar steam methane reforming techniques, 31 in which emerging and established technologies were combined.…”

Thermodynamic equilibrium analysis of oxy‐dry reforming of biogas with CO2 sequestration using Aspen HYSYS

“…It is suggested that CO 2 footprints ought to be brought down to net‐zero around 2050 to restrict the global temperature increment below 1.5°C by 2100 4 . Contrary, there has been a continuous debate on the energy crisis due to the limited reserve of fossil fuels 5 . Thus, to address the conventional fuels scarcity and limit GHG emissions, more sustainable and alternative (wind, geothermal, photovoltaic, solar, biomass, hydroelectric, etc.)…”
