Production of Substitute Natural Gas Integrated with Allam Cycle for Power Generation

چکیده
The accumulation of energy from non-programmable renewable sources is a crucial aspect for the transition. Using surplus electricity sources, power-to-gas plants allow to produce substitute natural gas (SNG) that can be injected in existing infrastructure large-scale and long-term storage, contributing grid decarbonisation. plant layout, method used carbon dioxide capture possible cogeneration increase efficiency convenience SNG synthesis plants. In this work, system simultaneous production starting biomass fluctuating renewables proposed, using based on Allam thermodynamic cycle as power unit. uses supercritical CO2 evolving fluid oxycombustion gaseous fuels, thus greatly simplifying capture. proposed system, performed syngas electrolytic oxygen. generated by means captured, it subsequently together with hydrogen through thermochemical methanation. also coupled solid oxide electrolyser gasifier. whole was analysed an energy-related point view. results show overall 67.6% LHV basis (71.6% HHV basis) significant amounts high-calorific-value SNG, whose composition could compatible network.

Simulation of Bioreactors for PHB Production from Natural Gas
Recently, many economic studies of poly(3-hydroxybutyrate) PHB production on an industrial scale, and the impact of replacing petrochemical polymers by PHB were carried out, clearly indicating that the most crucial factors to reduce the cost of producing biopolymers are allotted to the application of microbial production strains capable of high productivi...
متن کاملIntegrated Natural Gas, Heat, and Power Dispatch Considering Wind Power and Power-to-Gas
A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas,...

متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
