摘要

低能耗化学吸收剂开发目前成为工业界焦点。针对北京低碳清洁能源研究院开发的NICE系列吸收剂，通过实验室测试其吸收-解吸性能、黏度参数、反应热和腐蚀性等性能，并在浙江大学中试平台对优选的NICE吸收剂进行了性能优化测试，考察了其在500 t/a的CO_2捕集装置上的再生能耗。结果表明，实验室测试中，与MEA吸收剂相比，NICE-2吸收剂的最大负载量提高了54.5%，循环负载量提高了61.2%，反应热降低了6%～20%，对304不锈钢的腐蚀速率下降了81.3%，黏度与已商业应用的吸收剂接近；中试实验中的CO_2脱除率超过80%，优化的最低再生能耗（以CO_2计）为2.85 GJ/t，液气比为1.82 L/m3。该研究初步验证了NICE吸收剂的低能耗性能，并为工业化应用提供了依据。

Abstract

The development of low energy consumption chemical absorbent has become the focus of the industry.The NICE series absorbents developed by National Institute of Clean-and-Low-Carbon Energy in China were tested in the laboratory for their absorption-desorption performance

viscosity parameters

reaction heat and corrosivity

and the optimized performance of the NICE absorbents was tested on the pilot scale of Zhejiang University to study the renewable energy consumption on a 500 t/a CO_2 capture device. The results showed that

in laboratory test

compared with MEA absorbent

the maximum loading of NICE-2 absorbent increased by 54.5%

the cyclic loading increased by 61.2%

the reaction heat reduced by 6%～20%

the corrosion rate of 304 stainless steel decreased by 81.3%

and the viscosity was close to that of commercial absorbents. In pilot scale test

the CO_2 removal rate exceeded 80%

and the optimized minimum regeneration energy consumption(calculated by CO_2) was 2.85 GJ/t and the liquid gas ratio was 1.82 L/m3. This study preliminarily verified the low energy consumption performance of the NICE absorbents and provided a basis for their industrial application.
