Article
Full-text available
Combining a methanation step with biomass gasification requires an intensive tar removal process that reduces its content down to 1 mg/Nm 3. In this paper, low temperature processes are suggested for treating tar and reducing its content to the acceptable limit. However, the gas must be pre-treated prior to the low temperature process in order to r...

The increase in energy demand and the need for lower CO2 emissions have increased the importance of natural gas as the cleanest fossil fuel in the energy market. Natural gas is mainly transported using pipelines or as liquefied natural gas (LNG). LNG is stored and transported in cryogenic storage tankers, where a part of the LNG evaporates, generat...
Article
Full-text available
Biomass gasification is the thermo-chemical conversion of biomass into producer gas. The latter can be then integrated in a combined heat and power unit or chemically converted into biofuels. Tar formation during biomass gasification is the main process disadvantage. Tar leads to fouling and clogging problems in the process, in addition to catalyst...

Full-text available
High-temperature steam/CO2 electrolysis process has been the scope of study for the last decades. This study confers a feasible and environmental approach to convert low-carbon electrical energy into chemical energy, stored in the form of synthetic gas (H2 and CO) to be further processed in line with the final use target. It focuses on the Power-to...
Article
Full-text available
Biomass gasification is being regarded as an efficient process for the production of heat and power and even for the conversion of biomass into biofuels. Its main drawback is the non-negligible tar formation within the process. As the producer gas temperature decreases in the downstream equipment, tar will condense leading to the fouling, blocking...
Article
Biomass conversion into biofuels and biogas is a promising way for power and heat generation. Lately, research has focused on the production of biomethane based on biomass gasification followed by methanation as an alternative to fossil natural gas. The challenge of this process remains in the intensive gas cleaning and required tar removal. In ord...
Article
A novel purification technology for raw biogas streams is proposed and it is based on the use of a superacid solution within a bubble column reactor. The solvent is a mixture of sulfuricacid (H2SO4(aq), 95.0 wt.%) and acetic acid glacial (CH3COOH(l), ≥99.8 vol.%), both commercialgrades. A mixture with a molar ratio of 9/1 for H2SO4(aq)/CH3COOH(l) r...

Strengthening of environmental regulations demands for novel or enhanced technologies for Flue Gas Desulfurization (FGD). A fixed-bed reactor using sodium bicarbonate (NaHCO3(s)) is proposed to eliminate sulfur dioxide (SO2) in flue gases up to the environmental regulation limits, leading to a maximum heat energy recovery. A numerical model was dev...

In the light of the alarming impending energy scene, energy efficiency and exergy efficiency are unmistakably gathering momentum. Among efficient process design methodologies, literature suggests pinch analysis and exergy analysis as two powerful thermodynamic methods, each showing certain drawbacks, however. In this perspective, this article puts...

Cryogenic separation is one of many CO2 capture technologies developed for upgrading biogas or for CO2 separation from flue gases. In order to better understand the CO2 frosting phenomena, in this paper, CO2 frost growth is modelled considering deposition on a flat plate. The frost layer is modelled as a porous medium with heat and mass transfer oc...
Conference Paper
Cold-driven capture is known as one way of capturing CO2 and other pollutants from exhaust gases and from methane production systems. These processes frequently carry out CO2 frosting from gas to solid phase rather than from liquid phase. For gas to solid phase change, the equipment used as heat exchanger should provide a sufficient surface to tran...

Since the advent of the industrial age, the planetary energy demand has substantially increased to improve daily comfort. In a view to counterbalance the growing energy consumption of fossil fuels, such as natural gas, various strategies have been deployed for increasing the share of renewable energy (i.e., solar, wind, biogas...) in the global en...
Article
Full-text available
Chemical absorption is a frequently used post-combustion process that separates CO2 from gaseous compounds of the flue gases with the use of specific solvents for which the main drawback is their cost of regeneration. In order to overcome this problem, the new Thermomorphic Lipophilic Biphasic solvents are here studied. The limited solubility of th...

Highly emissive fossil origin CO2 systems are mainly combustion based. Presenting considerable investment costs and potential leaks into the environment as drawbacks, conventional amine solvent based processes remain the most mature technological option for CO2 capture. In the regeneration step of solvents, the energy consumed in these processes is...

Methyl mercaptan (CH_3 SH) absorption kinetics was studied for a hybrid solvent mixture consisting of diethanolamine/water/methanol for concentrations of 40/40/20 wt% and 40/20/40 wt% respectively, and for temperatures between 313.9 and 353.0 K. CH_3 SH is usually found in sour gases needing to be removed along with acid gases; therefore, physico-c...

The low attractiveness and competitiveness of carbon dioxide capture processes play against their deployment. Besides considerable investment costs for capture units and potential leakage of amines into the environment, conventional amine-aqueous solvents commonly used consume steam at temperatures ranging from 120 °C till 140 °C for the regenerati...

Simulation of solid-liquid CO2 phase transition in a liquid flow through CFD software, in order to prevent plug formation in CO2 transportation near the triple point.
Project
The project is aimed at identifying the "energy pathways" for energy recovery in industrial processes. "Energy Pathways" is used for a set of technologies (e.g. heat exchangers, heat pump) allowing to transfer or transform energy from a source (e.g. exhaust gas from a boiler) to a sink point (e.g. water).
