“…Thus, the energy consumption of the process is not constant despite the constant operating flow rate of biogas. The biomethane obtained as a by-product from the separation of the carbon dioxide is supplied to the liquefaction unit, operating according to the Linde industrial process [25]. Details of the models are discussed in the following section.…”

In the recent years, European Countries are paying more and more attention to the issue of greenhouse gases emissions due to the road transport sector. In particular, the fuel consumption due to the heavy road transport is one of the most relevant issues both for the weight and the long distances that they cover. In addition, the cost of the natural gas dramatically increased in many European countries due to recent international crisis. Thus, finding alternative ways of producing natural gas from renewable sources would be of great economic and environmental impact for the current global asset. In this work, a dynamic thermoeconomic analysis of a plant producing bio liquefied natural gas (bio-LNG), driven by renewable sources, to meet the fuel demand of a fleet of heavy trucks is proposed. The plant consists of a plug flow reactor digesting the organic fraction of municipal solid wastes in mesophilic conditions. The biogas upgrading model and the biomethane liquefaction models are in detail developed in MATLAB. The whole system is integrated in TRNSYS for dynamic simulation purpose. Then, the bio-LNG is used to meet the fuel demand of heavy trucks which cover relevant distances all over the region of Campania, in the South of Italy. The environmental impact related to the avoided emissions due to the use of bio-LNG is analysed together with the economic feasibility of the proposed system. The results of the thermoeconomic simulation show that the system has high capital costs, close to 85 M€ despite the fundings granted for bioLNG trucks purchasing. However, the fundings for the biomethane production and selling are enough to guarantee a remarkable economic feasibility with a Simple Payback period of less than 2 years and a Net Present Value of 402 M€. Furthermore, the solution proposed is effective for the pathway of the green mobility, with a Primary Energy Saving of 91% and a reduction of CO2 emissions by 86%.

“…The following hypotheses are intended to simulate an integrated structure 5,9,20,21 : The effect of pressure decrease in exchangers and drums has been ignored. Waste heat in various equipment has been ignored. Adiabatic efficiency of compressors, turbines, and pumps are examined to be 75%, 90%, and 90%, respectively. The outer diameter of the riser pipes is considered with 0.9 mm of pipe thickness. The properties of the fluid in the collector are constant during the process. The ambient temperature inside the collector glass cover is fixed and equal to 300 K. Nanoparticles with an average diameter of 15 nanometers are considered. …”

“…Therefore, it is possible to carry CO 2 in one direction and different loads in the other direction using multipurpose vessels (MPV) 8 . Ghorbani et al 9 investigated a combined process for the separation and liquefaction of CO 2 using post‐combustion capture with chemical absorption and the DPLH system at non‐peak hours. Organic Rankine power production systems and gas turbine combined plant were used in peak hours.…”

Greenhouse gas emissions into the atmosphere have had devastating environmental effects, including ozone depletion and global warming. Carbon dioxide (CO2) is widely used in oil and gas plants, the food industry, and as a working fluid in the power industry. Carbon dioxide is liquefied for long‐term storage, to be transported to remote areas, and is used for peak shaving in the power plants. Solar flat plate collectors and wasted heat from the CO2 liquefaction system can be used in power plant systems. Also, the use of nanoparticles in the collectors improves the thermal properties of the working fluid and increases the efficiency of solar collectors. This study has developed a new hybrid system for CO2 liquefaction using Linde–Hampson system, Kalina power generation unit, and flat plate solar collectors. The Linde–Hampson system's dissipated heat and solar collectors are used to supplying part of the power of the CO2 liquefaction system. The combined system produces 9416 kmol/h of liquid CO2 by absorbing 35.97 MW of power. The Kalina power generation unit provides 9.546 MW of power by absorbing 76.98 MW of the CO2 liquefaction cycle's dissipated heat and 91.18 MW from flat plate collectors. Based on the output of exergy assessment, exergy efficiency and exergy degradation of the developed integrated structure are 44.16% and 118.3 MW, respectively. Moreover, significant portions of exergy destruction in the combined process belong to solar collectors (74.68%), heat exchangers (12.47%), and compressors (7.157%), respectively. The use of Al2O3 nanoparticles in pure water has been investigated for heat transfer in flat panel solar collectors. According to the sensitivity analysis results, as the volume ratio of particles in nanofluid increases to 6%, the production capacity of the Kalina cycle and exergy efficiency improves to 9.56 MW and 9.522%, respectively. Also, as the pressure of the pumped fluid in the Kalina cycle increases from 800 to 1600 kPa, the exergy yield of the Kalina cycle and the exergy yield of the whole combined system increase to 36.34% and 44.26%, respectively.

“…Ghorbani et al studied a combination power generation system. They concluded that if the combustion chamber's inlet air steam was reduced to 250.0 kg/s, the total system's thermal efficiency will reach 56.15% [16][17][18]. Su et al studied and identified the possible consequences of increasing clean energy production in key EU countries.…”

Thermal power plants play a significant role in generating power, electricity, and energy consumption in the world, especially in developing countries. Therefore, the energy analysis of these power plants is very useful to increase the efficiency of systems and reduce energy consumption. One of the components of power plants that play a great role in energy consumption and recovery is the feedwater heater. In this study, a design method-based pinch technology for feedwater heaters of a coal power plant is presented. This method is used to reduce the irreversibility of heat transfer in feedwater heaters in this power plant. This study is performed on 6 feedwater heaters, which are similar in pairs. The results of this method show that this method is feasible for this system and the results also show that the implementation of this method with a Pinch range of 10 °C indicated a deficit hot utility of about 48.54 MW. Also, the amount of power plant efficiency improvement is 12.12%, and according to the Pinch method, could reduce the energy price of the power plant by about 125489 $/year.
