Mathematical modelling of gasification process of sewage sludge in reactor of negative CO2 emission power plant
Abstrakt
Sewage sludge is a residue of wastewater processing that is biologically active and consists of water,organic matter, including dead and alive pathogens, as well as organic and inorganic contaminants suchas polycyclic aromatic hydrocarbons (PAHs) and heavy metals. Due to the nature of sewage sludge and itspossible influence on human health and wellbeing, it is a subject of various regulations. Currently,sewage sludge is considered as biomass, according to the new Polish act on renewable energy sources ofFebruary 20, 2015 and its novel version of July 19, 2019. This study presents a novel model, along with acomparison with experimental results. The model could be used for sewage sludge gasification modellingfor accurate assessment of the performance of novel concepts bioenergy with carbon capture and storage(BECCS) installations, using sewage sludge as a fuel. The composition of the dry produced gas, deter-mined experimentally, yields: XCO¼0.093, XCO2¼0.264, XCH4¼0.139, XCxHy¼0.035, and XH2¼0.468.Performed modifications to the original Deringer-with-Gumz-modification gasification model allowed toobtain good agreement with the experimental results, reaching XCO¼0.071, XCO2¼0.243, XCH4¼0.139,XC3H8¼0.035, and XH2¼0.512. The main novelty in the formulas of the internal model was due topropane inclusion, which was not found in the literature before. Additionally, sulphur dioxide wasapplied in exchange for other sulphur components presented in the original model. Equilibrium con-stants were adjusted to suit the experimental model. For ease of calculation, the own code was used toiterate multiple temperatures. Included was the energy balance equation that is essential for verification
