Modeling and extensive analysis of the energy and economics of cooling, heat, and power trigeneration (CCHP) from textile wastewater for industrial low-grade heat recovery

摘要: Abstract The wastewater of the textile industry has approximately 60 °C temperature and a sufficient quantity organic compounds for biofuel yielding. low-grade heat recovery extractability effluent are considered to be two potentials generation various energy demands such as cooling, heat, power (CCHP). In this study, novel cascade trigeneration system driven by production source (BPS) from is introduced modeled energetically economically. BPS consists separate thermophilic mesophilic stirred tanks, which operate based on anaerobic digestion process. CCHP comprises Brayton top cycle (BC) three bottoming sub-systems, including Rankine (RC), modified Kalina/vapor-compression refrigeration (KVC34), water heating unit (WHU). feasibility demonstration parametrical optimization proposed were conducted thermal, technical, economic points view. results demonstrated that transcendent potential production. Moreover, methane content was enhanced roughly 28% dividing AD process into reactors. additionally, synchronic heating, efficiency around 62%, with five years discounted payback period.
