| 中文摘要: |
| 按照政府确定在2030年前碳达峰、提高能效和减排CO2的目标，引进新技术和新设备，探索采用清洁能源、调整生产工艺等节能减排措施和使用再生能源。油厂主要消耗能源是蒸汽、电和天然气。两条压榨生产线，规模分别为3 500 t/d和4 500 t/d，两条化学精炼生产线，规模分别为600 t/d和1 200 t/d。2016—2021年，消耗指标（两条生产线平均值）压榨蒸汽消耗从224.09 kg/t下降到194.34 kg/t，精炼从117.89 kg/t下降到36.69 kg/t；压榨电耗从23.69 kW·h/t增加到24.99 kW·h/t，精炼从14.92 kW·h/t下降到10.88 kW·h/t;压榨溶剂消耗从0.63 kg/t下降到0.47 kg/t;精炼天然气消耗从1.98 m3/t增加到2.35 m3/t(2018—2021年)。虽然该节能减排措施在油厂经济可行，但是没有与低碳和碳达峰关联，建议油脂行业权威机构组织专家建立油脂企业低碳排放指标认证体系和评价指标。 |

| According to the government′s determination to reach the peak carbon dioxide emissions, improve energy efficiency and reduce CO2 emission by 2030, new technologies and equipment have been introduced, energy saving and emission reduction measures including using clean energy and adjusting production process have been explored and renewable energy has been used.The major energy source in the oil plant are steam, electricity and natural gas. There are two press production lines with the capacities of 3 500 t/d and 4 500 t/d respectively, and two chemical refining production lines with the capacities of 600 t/d and 1 200 t/d respectively.From 2016 to 2021, the energy comsumption(average value of two production lines)of the steam consumption in press line decreased from 224.09 kg/t to 194.34 kg/t, and in refining line it decreased from 117.89 kg/t to 36.69 kg/t;the electricity consumption in press line increased from 23.69 kW·h/t to 24.99 kW·h/t, and in refining line it decreased from 14.92 kW·h/t to 10.88 kW·h/t; the solvent consumption in press line decreased from 0.63 kg/t to 0.47 kg/t;the natural gas consumption in refining line increased from 1.98 m3/t to 2.35 m3/t（2018-2021）. Although the energy saving and emission reduction measures were economically feasible in oil plants, they were not related with low-carbon and peak carbon dioxide emissions.It is suggested that the authoritative organization of the oil industry should organize experts to establish a low-carbon emission index certification system and evaluation index for oil enterprises. |
