在二氧化碳管输环节，该项目创新研制出我国首台可满足超临界管输需求的八级整体齿轮式二氧化碳压 缩机，可将捕集到的气态二氧化碳压缩至超临界态，提高管道输送效率，大幅降低输送能耗与成本。 华能正宁电厂厂长张延伟表示，作为全球最大的煤电碳捕集示范工程，该项目的二氧化碳捕集率超过 90%，每年可捕集二氧化碳150万吨，相当于处理了60万辆汽车一年的碳排放量，可助力燃煤电厂实现 大规模工业化深度减排，推动煤电绿色清洁发展，助推碳中和目标实现。 据介绍，该项目在碳捕集、压缩、封存等关键环节突破多项技术瓶颈，创造多项"全球首次"与"国内首 创"，核心装备也100%实现国产化。在二氧化碳捕集领域，他们创新采用复合式吸收塔"二塔合一"设 计，将烟气预洗涤与碳捕集环节深度集成，解决了传统工艺输送路线长、阻力大的能耗问题，并通过富 液分流、中间循环冷却等多种节能技术，实现热量利用最大化，整体节能效果显著。 近日，全球规模最大的煤电碳捕集示范工程在华能甘肃正宁电厂完成72小时试运行，正式投入运营。这 标志着我国碳捕集、利用和封存(CCUS)技术实现从"万吨级示范"到"百万吨级工业化应用"的跨越，为 全球煤电绿色低碳转型提供"中国方案" ...

Group 1 - The US tariff policy and other adverse factors pose significant challenges to chemical exporters in the Gulf Cooperation Council (GCC) region, which consists of six Middle Eastern countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE [1] - The Gulf Petrochemicals and Chemicals Association (GPCA) emphasizes the importance of enhancing cooperation with Asian markets, particularly China, as GCC chemical producers have joint ventures in China, South Korea, Malaysia, and Singapore, processing approximately 2.7 million barrels of crude oil daily and operating over 23 million tons of downstream petrochemical capacity annually [1] - Despite the challenges posed by US tariffs, there are opportunities for GCC chemical exporters, as a 10% baseline tariff could increase the prices of GCC chemical products in the US market, particularly affecting high-volume, price-sensitive products like urea, paraxylene (PX), and polyethylene terephthalate (PET) [1] Group 2 - In 2023, Asia accounted for over half of the total exports from the GCC region, with China, India, and Turkey being the primary markets. If China reduces imports from the US, GCC can fill this gap, provided they act quickly to capture market share and diversify trade partners [1] - The GCC region's chemical producers have a competitive advantage over those relying on naphtha due to fluctuating oil prices, and there is a strong emphasis on optimizing energy usage and focusing on high-value projects [1][2] - GCC chemical companies are shifting investments towards specialty elastomers, crude oil-derived chemicals, and downstream sectors such as packaging and electric vehicle materials, with a utilization rate of approximately 90%, significantly higher than most global peers [2] Group 3 - Supply chain resilience has become a key advantage for GCC chemical producers, who must predict, adapt, and seize opportunities arising from geopolitical conflicts and disruptions [2] - Four strategies have been proposed to address supply chain challenges: flexibility in export routes, transparency from production to end-user, establishing regional buffer stocks in key import markets, and utilizing digital risk forecasting [2] - The use of AI, blockchain, and IoT tools is transforming supply chain management from reactive to predictive, while diversified sourcing and strategic inventory reduce reliance on a single region [2] Group 4 - GCC countries will continue to leverage their cost advantage in natural gas while also committing to energy transition, aiming to adjust 25% to 50% of their energy structure to renewable sources by 2030 [3] - Significant investments are being made in carbon capture, utilization, and storage (CCUS), with the region capturing 4.4 million tons of CO2 annually, accounting for 10% of global CCUS capacity [3] - Hydrogen production is another focus of the GCC's energy transition, with ambitious targets set by Oman, UAE, and Saudi Arabia for annual hydrogen production by 2030 and 2031 [3]
