向新而行︱减碳增效 从温室气体到“绿色功臣”，二氧化碳的“逆袭”之路？

Core Viewpoint - The article emphasizes the importance of energy transformation as a strategic precursor to productivity advancement, highlighting the role of carbon capture, utilization, and storage (CCUS) technology in reshaping the relationship between humanity and carbon [2][4][15]. Group 1: CCUS Project Overview - A significant CCUS project in Shandong, known as the Qilu Petrochemical - Shengli Oilfield million-ton-level demonstration project, was launched in March 2022, focusing on environmental monitoring [6]. - This project is capable of reducing carbon dioxide emissions by 1 million tons annually, equivalent to planting nearly 9 million trees or removing about 60,000 economy-class cars from the road for a year, while also contributing to an increase of nearly 3 million tons of crude oil production over the next 15 years [7]. Group 2: Technology and Process - The CCUS facility operates like a large "industrial lung," capturing carbon emissions from petrochemical production processes that would otherwise be released into the atmosphere [8]. - The captured high-concentration exhaust undergoes a series of complex processes, resulting in liquid carbon dioxide with a purity of 99.9% and a temperature of -20 degrees Celsius, which is then stored in large "carbon banks" and transported safely to oilfields [8]. Group 3: Enhanced Oil Recovery - Injecting carbon dioxide underground into oil reservoirs, particularly those deeper than 3,000 meters, helps to mobilize previously stagnant crude oil, significantly improving oil recovery rates [11]. - This method transforms the state of crude oil from "standing" to "running," facilitating better flow within the geological formations [11]. Group 4: Industry Benchmark and Future Prospects - The Qilu Petrochemical - Shengli Oilfield CCUS project has established a comprehensive safety monitoring and early warning system, with over 27,000 monitoring points for air, soil, and groundwater [13]. - As a benchmark for carbon circular economy in China's petrochemical industry, this project has achieved commercial operation ahead of many global CCUS initiatives still in experimental phases, showcasing China's commitment to energy transition and climate governance [14][15][16].
