“…However, SRM is an energy-intensive process because of its high temperatures (ca. 900 • C) to favor methane conversion, and high steam-to-methane ratio (S/C = 3-4) to limit the catalyst deactivation by coke deposition [10,13,14]. Consequently, energy is lost during syngas cooling to the temperature of downstream processes (i.e.…”

“…The major part of the equipment has the following configuration of the operating space: centrifugal pumps, disk extruders, disk cavitators, and other devices [5,6]. The intensification of the gas dynamics and heat exchange processes within the disk pulse devices resulting from their operating space optimization is of great importance, especially in terms of improving the already available or developing new energy-efficient heat machines [4,[7][8][9][10][11]. Studies dealing with the improvement of the energy efficiency of disk devices, which involve renewable and environmentally safe energy sources, represent one of the most important trends of the energy complex development [12,13].…”

The effect of basic parameters of the channels of disk pulse devices on the heat exchange efficiency was studied both analytically and experimentally, especially in terms of pulse acting on the heat carrier. A methodology to determine the main parameters, namely the pressure and the temperature of the heat carrier as well as the pulse effect on the fluid, was proposed. The mathematical models of the effect of the structural and technological parameters of the channels in the disk pulse device on the heat exchange efficiency were developed. The models’ adequacy was proved based on a series of experimental studies involving devices with one-stage and multistage systems of pulsed heat carrier processing. This enabled the development, testing, and implementation of practical construction designs of pulse disk heat generators for decentralized heating of commercial and domestic buildings with one-stage and multistage systems of pulsed heat carrier processing. Taking into account the results of the mathematical modeling, the developed method of multistage pulse action was proved experimentally and implemented in regard to the structural design of a working chamber of the disk pulse heat generator. An efficient geometry of the working chamber of the disk pulse heat generator was specified for its further integration into the system of decentralized heat supply. One of the developed heat generators with the multistage pulse action on the heat carrier was integrated into the heating system of a greenhouse complex with a 0.86–0.9 efficiency coefficient.

“…The periodic replacement of catalysts during the natural gas conversion will certainly influence the CAPEX and OPEX of the process. Additionally, in the same study by Hamid et al [71], increasing the water contents during steam reforming of natural gas, was reported to have a significant influence on the OPEX per hydrogen production as shown in Figure 5. Since water is needed to produce steam needed for the reforming process, the amount of steam produced is depended on the amount of water available.…”

“…Study has shown that process parameters such as the flowrate of the reactants, and the reaction temperature usually influence the amount of CO 2 emissions and the process economics [71]. A sensitivity analysis reported by Hamid et al [71] revealed that the increase in the methane flowrate during steam methane reforming resulted in the increase in the CAPEX, OPEX and the CO 2 emissions as shown in Figure 4. The increase in the methane flowrates results in a corresponding increase in the conversion of the methane to gaseous products such as hydrogen, CO, and CO 2 .…”

An Overview of Economic Analysis and Environmental Impacts of Natural Gas Conversion Technologies

This study presents an overview of the economic analysis and environmental impact of natural gas conversion technologies. Published articles related to economic analysis and environmental impact of natural gas conversion technologies were reviewed and discussed. The economic analysis revealed that the capital and the operating expenditure of each of the conversion process is strongly dependent on the sophistication of the technical designs. The emerging technologies are yet to be economically viable compared to the well-established steam reforming process. However, appropriate design modifications could significantly reduce the operating expenditure and enhance the economic feasibility of the process. The environmental analysis revealed that emerging technologies such as carbon dioxide (CO2) reforming and the thermal decomposition of natural gas offer advantages of lower CO2 emissions and total environmental impact compared to the well-established steam reforming process. Appropriate design modifications such as steam reforming with carbon capture, storage and utilization, the use of an optimized catalyst in thermal decomposition, and the use of solar concentrators for heating instead of fossil fuel were found to significantly reduced the CO2 emissions of the processes. There was a dearth of literature on the economic analysis and environmental impact of photocatalytic and biochemical conversion processes, which calls for increased research attention that could facilitate a comparative analysis with the thermochemical processes.
