Abstract:V magistrskem delu smo preučevali možnosti integracije energije in vode v podjetju, ki se ukvarja s proizvodnjo perutninskega mesa. Vodno integracijo smo izvedli za različne obrate z uporabo uščipne metode. Energetsko integracijo smo izvedli za sistem hlajenja s simulacijo s programom Aspen Plus. Pri vodni integraciji virov in porabnikov vode, smo glede na podatke iz podjetja načrtovali sheme vodnih omrežij, kjer bi s ponovno uporabo vode zmanjšali porabo sveže vode, količino odpadne vode ter stroške sveže vode in čiščenja odpadne vode. Pri energetski integraciji smo predpostavili, da bi z zamenjavo hlajenja s kompresijskim ciklom s hlajenjem z absorpcijskim ciklom zmanjšali stroške hlajenja. Izvedli smo simulacijo kompresijskega in absorpcijskega cikla ter dodali toplotno črpalko, ki omogoča uporabo odpadne toplote. Simulacije smo izvedli z različnimi termodinamskimi modeli. Rezultat vodne integracije je pokazal, da lahko podjetje ob predlaganih spremembah prihrani svežo vodo in zmanjša stroške vode. Tudi rezultati simulacij so pokazali, da bi podjetje z implementacijo absorpcijskega hlajenja s toplotno črpalko zmanjšalo stroške hlajenja. Rezultati simulacij z različnimi termodinamskimi modeli so pokazali, da v našem primeru izbira modela nima velikega vpliva na rezultate.

Title:Evaluation of the potential for water, heat and energy integration within biogas process and other plants
Abstract:The possibilities of integration of water and energy consumers in a poultry meat production company were studied in this dissertation. Water integration was performed for different types of facilities using a pinch analysis method. Energy integration of cooling system was performed using Aspen Plus process simulation software. In water integration analysis, water networks where designed by using data provided by the company. Proposed water networks would reuse water between processes so that freshwater usage and wastewater production would reduce. The cost of fresh water and wastewater will therefore reduce too. In energy integration, a change of compression cycle-based cooling system with absorption-based cooling system was proposed to lower the costs of cooling. Both, compression and absorption-based cycles were simulated. We also simulated a heat pump for waste heat reuse. Different thermodynamic models were also tested and compared. Water integration analysis results showed that the proposed changes reduce the freshwater usage and the cost of freshwater. Simulation results also showed that the implementation of absorption-based cooling system with added heath pump for waste heat reuse reduce the cost of cooling. Results of thermodynamic model comparison show that the choice of thermodynamic model did not have an important influence on the results of the simulation.
Keywords:water integration, pinch analysis method, absorption cooling, heat pump.
