“…Such a study supports the accuracy of outcomes from 20-30% of the actual expense (Turton et al, 2008;Swanson et al, 2010;Robert and Tristan, 2013). Generally, the investigation includes the economic performance of the total investment cost, the unit cost of production, the net present value, the internal rate of return and the project payback period (Lee et al, 2011;Gebremariam and Marchetti, 2021).…”

“…Process simulation is commonly used before economic assessment (Lee et al, 2011). Many commercial process simulators are available, such as ASPEN Plus, Super Pro (Gebremariam and Marchetti, 2021). However, ASPEN Plus version 12 was used in this study due to its comprehensive databases, vast component libraries and advanced calculation techniques (Abdulwahab et al, 2014).…”

Importance of the work:A new approach was investigated using acid oil from acidulation for its economic feasibility in biodiesel production.Objectives: To investigate the esterification conditions of biodiesel production from acid oil, and conduct process simulation and cost investigation using the ASPEN software. Materials & Methods: Reaction time (1-6 h) and the methanol-to-oil molar ratio (20:1-30:1) were varied with a fixed 4% H 2 SO 4 catalyst at, 60 °C and 500 revolutions per minute. Based on the experimental data, the optimized conditions determined using the Minitab-17 software were used in the ASPEN process simulation. Then, the economic feasibility and sensitivity analysis were examined. Results: The acid oil comprised 33.63% free fatty acid, 72.36% fatty acid methyl ester and 1.3% water. After esterification using an acid catalyst, Minitab determined the optimum conditions of biodiesel production from the acid oil at 3.4 h reaction time and a 25.9:1 methanol-to-oil ratio, which produced biodiesel containing fatty acid methyl ester of 96.8% and free fatty acid of 0.32%. Consequently, 26,579.5 kg/d biodiesel were produced from 27,300 kg/d acid oil and 30,903 kg/d methanol, with 95% conversion. Finally, the project was economically feasible based on the net present value (USD 34,092,719), the internal rate of return (56%), the payback period (5.1 yr) and the production cost (USD 0.77/L). Main finding: Acid oil could be used as new raw material for biodiesel production. The results showed that the production process was economically suitable for investment. Minitab was a helpful tool for optimization, while ASPEN was excellent for process simulation and economic assessment.

“…The production of biodiesel from first-generation feedstocks is more suitable and viable in those regions where agricultural land and water resources are abundantly available. However, the production of biodiesel from edible oil crops is not always favorable as it increases land usage and can cause a shortage of food supply in the future. , The production of biodiesel from non-edible oil crops does not affect the food chain supply, but land and water resources can be affected . Past research depicted that the synthesis cost of biodiesel from non-edible oils is very high as compared to that of petro-diesel.…”

The energy demand of the world is skyrocketing due to the exponential economic growth and population expansion. To meet the energy requirement, the use of fossil fuels is not a good decision, causing environmental pollution such as CO2 emissions. Therefore, the use of renewable energy sources like biofuels can meet the energy crisis especially for countries facing oil shortages such as Pakistan. This review describes the comparative study of biodiesel synthesis for various edible oils, non-edible oils, and wastes such as waste plastic oil, biomass pyrolysis oil, and tyre pyrolysis oil in terms of their oil content and extraction, cetane number, and energy content. The present study also described the importance of biodiesel synthesis via catalytic transesterification and its implementation in Pakistan. Pakistan is importing an extensive quantity of cooking oil that is used in the food processing industries, and as a result, a huge quantity of waste cooking oil (WCO) is generated. The potential waste oils for biodiesel synthesis are chicken fat, dairy scum, WCO, and tallow oil that can be used as potential substrates of biodiesel. The implementation of a biodiesel program as a replacement of conventional diesel will help to minimize the oil imports and uplift the country’s economy. Biodiesel production via homogeneous and heterogeneous catalyzed transesterification is more feasible among all transesterification processes due to a lesser energy requirement and low cost. Therefore, biodiesel synthesis and implementation could minimize the imports of diesel by significantly contributing to the overall Gross Domestic Product (GDP). Although, waste oil can meet the energy needs, more available cultivation land should be used for substrate cultivation. In addition, research is still needed to explore innovative solvents and catalysts so that overall biodiesel production cost can be minimized. This would result in successful biodiesel implementation in Pakistan.

“…More recently, SuperPro Designer was used for technoeconomic analysis for various manufacturing processes of chemicals, biochemicals, and food. These include the production of cocoa butter [37], monoclonal antibody [38], biodiesel [39], nanomaterials [40], catechin [41], biomass pyrolysis products [42], and thorium extraction from monazite [43]. It is also worth noting that Monte Carlo simulations were also reported for use in some of the above works where SuperPro Designer was utilized (e.g., [38,40]).…”

Synthesis of Ti Powder from the Reduction of TiCl4 with Metal Hydrides in the H2 Atmosphere: Thermodynamic and Techno-Economic Analyses

et al. 2021

Titanium hydride (TiH2) is one of the basic materials for titanium (Ti) powder metallurgy. A novel method was proposed to produce TiH2 from the reduction of titanium tetrachloride (TiCl4) with magnesium hydride (MgH2) in the hydrogen (H2) atmosphere. The primary approach of this process is to produce TiH2 at a low-temperature range through an efficient and energy-saving process for further titanium powder production. In this study, the thermodynamic assessment and technoeconomic analysis of the process were investigated. The results show that the formation of TiH2 is feasible at low temperatures, and the molar ratio between TiCl4 and metal hydride as a reductant material has a critical role in its formation. Moreover, it was found that the yield of TiH2 is slightly higher when CaH2 is used as a reductant agent. The calculated equilibrium composition diagrams show that when the molar ratio between TiCl4 and metal hydrides is greater than the stoichiometric amount, the TiCl3 phase also forms. With a further increase in this ratio to greater than 4, no TiH2 was formed, and TiCl3 was the dominant product. Furthermore, the technoeconomic study revealed that the highest return on investment was achieved for the production scale of 5 t/batch of Ti powder production, with a payback time of 2.54 years. The analysis shows that the application of metal hydrides for TiH2 production from TiCl4 is technically feasible and economically viable.
