Effect of Moisture Content on Lignocellulosic Power Generation: Energy, Economic and Environmental Impacts

Abstract

Abstract:The moisture content of biomass affects its processing for applications such as electricity or steam. In this study, the effects of variation in moisture content of banagrass and energycane was evaluated using techno-economic analysis and life-cycle assessments. A 25% loss of moisture was assumed as a variation that was achieved by field drying the biomass. Techno-economic analysis revealed that high moisture in the biomass was not economically feasible. Comparing banagrass with energycane, the latter was more economically feasible; thanks to the low moisture and ash content in energycane. About 32 GWh/year of electricity was produced by field drying 60,000 dry MT/year energycane. The investment for different scenarios ranged between $17 million and $22 million. Field-dried energycane was the only economically viable option that recovered the investment after 11 years of operation. This scenario was also more environmentally friendly, releasing 16-gCO 2 equivalent/MJ of electricity produced.

An Analysis Study of Some Agricultural Wastes and Their Impact on the Environment

“…Therefore, thermochemical can be used (20), because in this method the product of fuel will be higher and have higher efficiencies (30). In addition, the results revealed, that these types of biomass waste plant (Malva arborea, and Berpine) are more environmentally friendly (8), because this sample releases less CO, and CO2 based on the percentage of these contents (27). The concentrations of the two types of elements (Malva arborea, and Berpine) in biomass waste plant, summarised in Figure 3, Figure 4, and Figure 5.…”

Lignocellulosic biomass from agro‐industrial residues in South America: current developments and perspectives

“…Soil disposal is a common alternative when lignocellulosic biomass burning is not economically favorable, as is the case with residues of i) high moisture content and low LHV, ii) low bulk density, iii) easy degradation, or iv) high transport costs . The organic material generated by the decomposition of the lignocellulosic biomass can return original nutrients, such as phosphorus and potassium, to the soil, improving soil physical characteristics .…”

A sutible model for drying kenitic of wood fiber using halogen moistuer analayzer

“…When utilizing biomass as fuel, the high moisture content of the biomass affects the combustion strongly. For example, the calorific value of dried biomass is 3.5 MW h/ton, while wet biomass is 2.2 MW h/ton (Rajendran 2017;Soni 2007). As aforementioned, drying wood and cellulose fibers consumes significant energy in all related applications, and it significantly impacts the ultimate pricing of products (Konopka et al 2021).…”
