“…The total plant cost (TPC) is the sum of the TPDC and the TPIC. It also comprises working capital and startup costs, which are the funds needed to support operations and pay for goods and services until the plant generates revenue (Adeyi et al, 2022). Based on a study by Attarbachi et al (2023), it was assumed in this study that the price of glycerol will range between 427.48 and 854.97 USD/ton for both types of feedstocks.…”

Increasing demand in the Asia-Pacific region, particularly from China, India, and Southeast Asia, as well as new uses for the product such as a humectant in cosmetics and other personal care products, and advances in related technologies, have contributed to a thriving worldwide glycerol industry. Regarding this, glycerol manufacturing performance using SuperPro Designer® Simulator was studied. Enzymatic hydrolysis method was selected for glycerol manufacturing where waste cooking palm oil (PWCO) and waste cooking sunflower oil (SWCO) were used as feedstock. In this study, block flow diagram (BFD) and process flow diagram (PFD) for glycerol manufacturing were synthesized and economic potential of the production was evaluated. The operating conditions for the enzymatic hydrolysis process were carried out at pH of 5.5, temperature of 35.3 and 40℃, agitation speed of 300 rpm, input flow rate of 1000 kg/batch and reaction time of 2 hours. According to the simulation results, the glycerol yield from PWCO was higher than SWCO which were 95.71 kg/batch or 110,116.48 kg/year and 1.89 kg/batch or 2,179.27 kg/year, respectively. However, when the reactor temperature was changed from 35.3°C to 40°C, there were no changes in glycerol yield from either feedstock. For economical evaluation it was found that the capital investment for the glycerol production when using PWCO was lower compared to SWCO which were 8,962,000 USD and 37,900,000 USD, respectively. In addition, for glycerol production of 100 metric tonnes per year, using PWCO as the feedstock results in a lower operating cost of 1,212,000 USD per year when compared to SWCO, which has an operating cost of 17,525,000 USD.

“…Fixed Capital Investment Summary.According toAdeyi et al (2022) andSingh and Rosentrater (2019), the expense of daily maintenance and administration is referred to as operating cost. Operational costs typically comprise raw material purchases, labour costs, facility costs, laboratory costs, and utility costs.…”

“…In addition to Turton et al's (51) cost of manufacture technique, industrial units' economic viability for essential oil extraction from natural products can also be determined using this strategy. Industrial process simulators, such as the SuperPro Designer ® (version 8.5), have been used to assess the total cost of production, taking into account the operating expenses, operative labor, utility expenses, waste disposal, and materials procurement (53)(54)(55). It is important to know that nonconventional reactors have higher running costs than conventional reactors when estimating capital investment costs.…”

Context: Nonconventional extraction methods, such as microwave, supercritical fluid, and ultrasonic, are known to be veritable means of producing solvent-free high-quality essential oils. Nonetheless, technical requirements for the utilization of these extraction technologies are often exorbitantly expensive, thereby limiting their utilization. Evidence Acquisition: Although these emerging extraction technologies have been reported to be efficient at a laboratory scale, their techno-economic analyses are necessary for proper upscaling. Scaling up nonconventional extraction has long been regarded as a critical constraint in larger industrial applications with a relatively limited body of published literature on more specific techno-economic analyses. Results: Therefore, an essential oil extraction unit’s techno-economic feasibility should be carefully assessed before an acquisition decision can be made for industrial upscaling. This review critically examined the implications of upscaling nonconventional extraction techniques while taking into consideration their techno-economic benefits. Conclusions: This study will undoubtedly assist researchers and industrial experts make an informed decision on the suitable extraction methods while taking into account the essential oil yield, quality characteristics, energy consumption, and operating costs.

This present study investigates the heat-assisted extraction (HAE) of bioactive antioxidants from Enantia chlorantha stem bark (ECSB). The effects of process parameters of operating temperature (OT: 35–55 °C), extraction time (ET: 100–200 min) and solid: liquid ratio (S/L: 1:20–1:50 g/mL) are determined on the total polyphenol content (TPC), antioxidant activity (AA) and extract yield (EY) using the D-Optimal design. Multi-criteria optimization is also conducted to determine the HAE optimum conditions. The integrated process for E. chlorantha stem bark extracts (ECBEs) production is thereafter designed with the optimum HAE conditions and techno-economically analysed. Three industrial ECBEs production setups (5, 100 and 1000 L extractor capacities) are analysed for probable scale-up and the risk & sensitivity analyses are conducted via Monte Carlo simulation. The HAE parameters affect the extraction process significantly. The OT, ET and S/L that maximize the TPC, AA and EY simultaneously are: OT = 54.10 °C, ET = 120.16 min and S/L = 1:50 g/mL. The 1000 L plant extractor setup is the most economical capacity having the least unit production cost (UPC) of 763.52 US$/kg ECBEs. The certainty of achieving 763.52 US$/kg ECBEs for the 1000 L capacity is 55.43% and the only variable with negative contribution (− 37.9%) on ECBEs UPC is the extract recovery variable.
