PERFORMANCE ASSESSMENT OF HYDROGEN/METHANOL PRODUCTION SYSTEM BASED ON PLASMA GASIFICATION OF MEDICAL WASTE
To achieve the harmless,reduced,and resourceful treatment of medical waste while enhancing energy and material utilization efficiency,a hydrogen/methanol production system based on plasma medical waste gasification technology is proposed to produce hydrogen/methanol.Among them,the hydrogen production system(scheme A)converts medical waste into hydrogen;The dual fuel system of hydrogen and methanol production(scheme B)converts medical waste into hydrogen and methanol.All schemes use a 30 t/d plasma gasifier and are evaluated and compared from a thermodynamic and economic point of view.The results show that the process efficiencies of scheme A and scheme B reach 70.07%and 67.96%,respectively.Due to the recycling of waste gas,the system breakdown efficiency of scheme B is 2.19 percentage points higher than that of scheme A.Compared with scheme B,scheme A has a shorter dynamic payback period of 4.40 years and a relatively higher net present value of 255.57 million yuan.
