The VOCs produced in the petrochemical industry are mainly long-chain hydrocarbons, mainly including alkanes, multi-chain isoalkanes, cycloalkanes, aromatic hydrocarbons, unsaturated hydrocarbons and other hydrocarbon substances. Tests have initially confirmed that 60% of VOCs tail gas can be subjected to catalytic cracking and reforming into solid oxide fuel cell (SOFC) fuel gas for SOFC power generation. VOCs tail gas is catalytically cracked into SOFC fuel gas and enters the anode side of the SOFC. It electrochemically reacts with oxygen ions coming from the cathode side to produce water and carbon dioxide, releasing electrons to form current. Specific process routes:VOCs desulfurization → reforming →SOFC power generation → catalytic combustion of tail gas → evacuation. Working temperature: 720-780℃; single cell power density: 300mW/cm2 (0.8V, 750 ℃); stack power: 1000W; stack life>5000 hours. For Shanghai Petrochemical Storage and Transportation Workshop, a SOFC system is adopted and VOCs are used to generate electricity. The annual exhaust gas can generate 4.06 electricity.106 degrees. If standard coal is used, 4.06 is produced106 kilowatt-hours of electricity produces 4.04782*106kg of carbon dioxide, that is, by using VOCs as fuel gas and combining SOFC systems, carbon dioxide emissions can be reduced by 4,047.82 tons per year, achieving energy conservation and emission reduction effects.
