燃气电厂化学吸收二氧化碳捕获系统运行参数与能耗分析
摘要:为明确燃气电厂二氧化碳捕集运行参数与系统用能关联机制，削减单位二氧化碳捕集能耗和成本，以450 MW级燃气电厂二氧化碳捕集与封存(carbon capture and storage，CCS)示范装置为研究对象，介绍CCS工艺的主要流程；通过对吸收塔和再生塔的系统性试验，对比分析了MEA和AMP-PZ这2种吸收剂的性能；考察烟气温度、吸收塔液气比、解吸塔压力、二氧化碳捕获率等工艺参数对再生能耗的影响。结果表明：MEA和AMP-PZ在吸收塔烟气温度为38 ℃、液气比分别为0.54和0.42、再生温度为112 ℃的运行条件下，再生能耗分别为4.49、4.24 MJ/kg。
Abstract：In order to clarify the correlation mechanism between carbon dioxide capture operation parameters and system energy use in gas-fired power plants, and reduce the energy consumption and cost per unit of carbon dioxide capture, the carbon capture and storage (CCS) demonstration device of a 450 MW gas-fired power plant was taken as the research object, and the main process of CCS process was introduced. The properties of MEA and AMP-PZ absorbers were compared and analyzed by systematic test of absorber and regenerator. The effects of flue gas temperature, liquid gas ratio of absorber, desorption pressure and carbon dioxide capture rate on energy consumption were investigated. The results show that under the operating conditions of MEA and AMP-PZ with flue gas temperature of 38 ℃, liquid-gas ratio of 0.54 and 0.42, and regeneration temperature of 112 ℃, the regenerative energy consumption is 4.49 and 4.24 MJ/kg, respectively.
