The current study presents the techno-economic analysis of the CLR-CC process. The CLR-CC process comprises of chemical looping reforming (CLR) of Natural Gas, water gas shift, CO2 capture and compression, and combined cycle power plant. A 1-D phenomenological model was developed using MATLAB and is used to study the performance of CLR, whereas the remaining part of the process was analysed using commercial software tools like Aspen and Thermoflow. The effect of design conditions in CLR, mainly the air flowrate to the oxidation reactor, oxidation reactor outlet temperature and the steam flowrate to the fuel reactor of CLR, on the overall techno-economic performance of the CLR-CC process is reported. The CH4 conversion in CLR, net electrical efficiency, CO2 avoidance rate and the Levelised Cost of Electricity (LCOE) have been identified as techno-economic performance indicators. For the sensitivity study carried out in this study through 12 cases, the net electrical efficiency of the CLR-CC process varies between 40.0 and 43.4 %, whereas the LCOE varies between 75.3 and 144.8 $/MWh, which is highly dependent on the fuel cost and process contingency rates.

Ion transport membrane (ITM)-based oxy-combustion systems could potentially provide zero-emissions power generation with a significantly reduced thermodynamic penalty compared to conventional carbon capture applications. This article investigates ITM-based oxy-combustion power cycles using an intermediate-fidelity model that captures the complex physical coupling between the two systems and accurately accounts for operational constraints. Coupled ITM-cycle simulation reveals hidden design challenges, facilitates the development of novel cycle concepts, and enables accurate assessment of new and existing power cycles. Simulations of various ITM-based zero and partial-emissions power cycles are performed using an intermediate-fidelity ITM model coupled to power cycle models created in ASPEN Plus®. The objectives herein are to analyze the prevalent ITM-based power cycle designs, develop novel design modifications, and evaluate the implementation of reactive ITMs. An assessment of the potential for these ITM power cycles to reduce both the thermodynamic penalty and reactor size associated with ITM air separation technology is conducted. The power cycle simulation and analysis demonstrate the various challenges associated with implementing reactive ITMs; hybridization (the use of both reactive and separation-only ITMs) is necessary in order to effectively utilize the advantages of reactive ITMs. The novel hybrid cycle developed herein displays the potential to reduce the size of the ITM compared to the best separation-only concept while maintaining a comparable First Law efficiency. Next, the merit of implementing partial-emissions cycles is explored based on a proposed linear-combination metric. The results indicate that the tradeoff between the main thermodynamic performance metrics efficiency and CO(2) emissions does not appear to justify the use of partial-emissions cycles.

“…The H 2 /CO ratio in the ATR process is equal to 2, which is suitable in the subsequent Fischer–Tropsch process . The ATR process for syngas production or hydrogen production of methane has gained much attention due to its high energy efficiency as compared to other processes such as steam reforming (SRM) or partial oxidation of methane (POX) …”

Annually billions of cubic meters of natural gas are flared around the globe at various oil and gas production sites. Natural gas flaring practices waste valuable energy resources that can be used for economic support and will also be beneficial to mitigate global warming effects. In this review, an overview of natural gas flaring impacts with respect to the environment with special emphasis on global annual natural gas flaring emissions and their reformation to energy-efficient fuels has been discussed. Initially, natural gas flaring emissions and their impacts in view of environmental pollution and global warming effects have been highlighted. The strategies to mitigate wastage to valuable energy resources through various flaring management strategies are also evaluated. In the main stream, various gas flaring reductions and utilization technologies based on their applications in the oil and gas industry and especially for remote oil and gas fields are discussed. Liquified natural gas (LNG) and compressed natural gas (CNG) technologies have been identified as the main gas flaring reduction methods based on their applicability, commerciality, and economical potential. In addition, gas to liquid (GTL) has been an advancing technology for the past many years toward its utilization of methane as a feed and converting it to useful industrial products such as synthesis crude and methanol. Finally, reformation technologies for synthesis gas (syngas) production such as thermal reforming, plasma reforming, and photoreforming are deliberated. Based on feed gas mixture, different reforming processes such as steam reforming of methane (SRM), dry reforming of methane (DRM), and bi-reforming of methane (BRM) are evaluated for hydrogen-rich syngas production. The future perspectives regarding gas flaring utilization technologies advancement with further improvements in utilization of flared gas to efficient energy fuels are proposed.
