碳捕集有"超级车间"——全球首台"二塔合一"复合式吸收塔。 传统碳捕集工艺中,脱硫后的烟气需要先进入预洗塔降温"洗澡",去除水分、残留石膏、粉煤灰及少量 二氧化硫、氮氧化物,再进入吸收塔,让二氧化碳被吸收溶剂捕获,两座塔独立运行,烟气输送路线 长、阻力大。 为突破这一瓶颈,项目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到 一个"超级车间",并通过中间循环冷却等多种节能技术,实现热量利用最大化,节能效果显著。 甘肃庆阳,华能正宁电厂2台100万千瓦燃煤发电机组"火力"全开,保障冬季能源供应。"2台机组满负荷 运行一天,可发4800万千瓦时电,能满足数百万户家庭一天的用电需求,绝大部分电量将通过特高压送 往山东。"电厂厂长张延伟说。 牛红伟解释道,这台压缩机有8个压缩缸,一步步给二氧化碳加压,填补了国内超临界压缩装备的空 白。总重量与传统单轴压缩机相比减少20%,效率提升10%,每压缩1吨二氧化碳可节约10千瓦时电, 为捕集后的二氧化碳大规模管道输送与封存提供设备支撑。 机组一旁,一位超级"碳捕手"正忙碌工作,助力煤电在顶峰保供的同时,更加清洁低碳,二氧化碳捕集 率超90%。这是今年9 ...
