Abstract

Sulphuric acid (H2SO4) is of immense importance to the chemical industry and humanity. The use of Aspen Plus modeling, simulation, and optimization via the contact process has enabled the production of grade sulphuric acid. Notably, the research findings highlight the sensitivity of water flow rate to the maximization of H2SO4 production. Through these methods, a production capacity of around 8 tons per day was achieved, with a purity level of 98.9%. This achievement significantly contributes to meeting the demand for sulphuric acid in various industries. Moreover, exploring alternative sourcing methods, such as utilizing elemental sulphur, offers the potential for further optimizing H2SO4 production. The benefits of improving H2SO4 production extend beyond the chemical industry. Sulphuric acid finds applications in agriculture, petroleum refining, pharmaceuticals, and metal processing. Enhancing the production process ensures a reliable supply for these sectors. In summary, sulphuric acid is indispensable to the chemical industry and humanity at large. Aspen Plus modeling and optimization techniques have successfully improved the production of high-grade sulphuric acid, resulting in increased capacity and purity. Exploring alternative sourcing methods further enhances production possibilities. These advancements have wide-ranging implications, benefiting multiple industries and driving progress in sectors reliant on sulphuric acid.

Abstract

Biomass blends with lignite coal (LC) normally have better co-combustion property, which in turn improves electricity output and reduces emissions. Given that global warming caused by emissions of CO, NOx, SO2, CO2 and NO from manufacturing industries and power plants is growing, this study seeks to find environmentally friendly alternative fuel to be employed. Here, suitable particle size of LC was combined with tree leaves (TL), cow dung manure (CDM) and banana tree waste (BTW) in the ratio of 90:10, 80:20, 70:30 and 60:40 each to form 16 samples (4 single and 12 blends). Thermal and combustion characteristics studies conducted during their combustion in an electric muffle furnace at 700  helped declare all blends as favorable with higher heating values ranging from 521179-892952 Btu/lb to be used as fuel in coal-powered plants. For moderately low emissions of flue gases, better thermal combustion property, high heating value (i.e., 892952 Btu/lb) and the highest electricity output, LC90 + CDM10 is the best blend discovered by this study. However, LC utilization still defeats the best performing blend in terms of lower emission with LC80 + TL20 having tolerably closer emission level compared to LC and a good substitute if emission must be kept as same level. Due to this shortcoming, further ratio adjustment or optimization and catalyst/additive addition is recommended to bring the emissions to environmentally friendly levels. It is also paramount to analyze the samples for chlorine concentrations to keep at desired composition in order not to risk a high temperature chlorine corrosion during co-combustion.
