An Integrated Poly-generation System and Analysis Based on Coupling of Tire Pyrolysis,Waste Plasma Gasification and Water Electrolysis
To enhance the treatment capacity of solid waste and achieve diversified utilization of waste,a novel integrated system for producing methanol and oil was proposed based on the coupling of refuse-de-rived fuel(RDF)plasma gasification,hydrogen supplementation from water electrolysis,and tire pyroly-sis.The system centered on a plasma gasifier which drives a tire pyrolysis subsystem,achieving staged uti-lization of energy.Results show that the energy efficiency of the system is 58.24％and the exergy efficien-cy is 64.41％,with main energy loss in methanol synthesis and main exergy loss in plasma gasification.According to the results of the economic analysis,the total investment of the system is 35.665 6 million yuan.With a system life of 25 years and a dynamic payback period(DPP)of 3.15 years,the net present value(NPV)of the final system can reach 171.771 0 million yuan.
