摘　　要：以散堆填料吸收塔作为反应器,采用单因素分析方法研究了吸收液进口温度、吸收当量比、停留时间和吸收液浓度等因素对CO_(2)捕集的影响,并采用正交试验对这些参数进行优化。结果表明:在实验条件下,各因素对CO_(2)捕集影响由大到小依次为吸收液进口温度、停留时间、吸收当量比和吸收液浓度;吸收液进口温度与停留时间对CO_(2)捕集有显著影响,吸收当量比和吸收液浓度对CO_(2)捕集影响较小;最佳工况组合为吸收液进口温度为40℃,停留时间为5 s,吸收当量比为100%,吸收液浓度为2.0 mol/L。Effect of absorbent inlet temperature, equivalence ratio, residence time, concentration of NaOH solution on CO_(2)capture in a random packed absorber reactor was studied by single-factor experiments, and these parameters were optimized using orthogonal test. Results show that under the experimental conditions, the effects on CO_(2)capture is in a descending sequence as inlet temperature, residence time, equivalence ratio and concentration. Both inlet temperature and residence time of NaOH solution have obvious influence on CO_(2)capture while minor effect of equivalence ratio and concentration exist. The optimum conditions are achieved at inlet temperature of 40 ℃, residence time of 5 s, equivalence ratio of 100%, and NaOH concentration of 2.0 mol/L.
