“…Flowsheets involving the GTL process and FT synthesis are available in the literature. [1,3,29,30,35] In this work, the GTL process with supercritical media was designed based on the GTL process developed by Bao et al [35] The flowsheet is shown in Figure 3. A summary of the process components is given next.…”

“…Gas-to-liquid (GTL) processes based on Fischer-Tropsch synthesis (FTS) are widely used technologies as a key step in converting hydrocarbons (e.g., natural gas, coal, or biomass) into liquid fuels. [1][2][3][4] In the process, syngas, a mixture of CO and H 2 , is converted catalytically to longchain hydrocarbons, which can be used as fuel products such as gasoline and diesel. FTS has mostly been used under gas phase conditions.…”

Inherent safety assessment during the design stage of chemical processes is typically conducted based on average values for design parameters. Under those conditions, the single‐point deterministic process performance assessment may be affected by the phenomenon known as the ‘flaw of averages’ in the presence of irreducible sources of uncertainty (performance evaluated at average conditions does not represent average performance). In this work, an inherent process safety assessment developed under a probabilistic formulation is presented. An evaluation of the proposed approach is performed in the case of a gas‐to‐liquid process system using a supercritical solvent for Fischer–Tropsch reactor systems. The pertinent uncertainty analysis is carried out using Monte Carlo simulation techniques to account for the propagation of uncertainty through the inherent process safety model and the derivation of probability distribution profiles for the associated metrics, thus statistically characterizing ranges of potential performance outcomes. The response variables were the autothermal reactor and the syngas flows. The results show that the input variables associated to the autothermal flow potentially generate the most hazardous conditions for the process. The results also show how the metrics are affected when uncertainty is explicitly taken into account at the design stage of the process, offering a more nuanced assessment and characterization of the inherent process safety profile.

“…These objectives include utilizing up to 58% of the accessible forest biomass for energy generation, achieving an overall reduction of 4% in emissions, and ensuring that the transportation sector is entirely powered by biofuel. Additionally, an estimation was made on the potential reduction of environmental impacts in the transportation sector of Norway by substituting fossil diesel with liquid biofuel derived from biomass from forests and woody wastes through the Fischer-Tropsch process (Jahangiri et al, 2023). The predicted greenhouse gas (GHG) reductions and decreases in greenhouse impacts resulting from the production and utilization of Fischer-Tropsch biofuel derived from forest wastes are projected to range from around 20% to 90% over a 100-year timeframe (Cheng et al, 2023).…”

The use of biomass is vital in reducing the negative effects of rising fossil fuel consumption. Given its quantity and diversity, forest biomass has garnered a lot of interest among the many kinds of biomass. This study evaluates the various strategies for transforming woody waste into usable biofuels. Carbon dioxide emissions from traditional energy generation systems could be mitigated through the direct utilization of forest biomass. Low energy conversion rates, as well as soot emissions and residues, are some of the problems that come up when directly using forest biomass. The sustainability of direct energy generation from forest biomass is also seriously threatened by the lack of constant access to biomass. Co-combustion with coal and pelletizing biomass is two solutions proposed for this issue. Co-combustion of forest biomass with coal has the potential to lower the process's emissions of carbon monoxide, nitrogen oxides, and sulfides. This article reviews and discusses the biochemical and thermochemical mechanisms that can transform forest biomass into a variety of liquid and gaseous biofuels. Future research using cutting-edge sustainability assessment tools like life cycle assessment, exergy, etc. should investigate the sustainability of forest biomass conversion processes to bioenergy further.
