| 摘 要： | 炼油厂石油碱渣中含有大量的残余碱、硫化物、酚类和环烷酸等，采用CO2中和法处理石油碱渣，考察了中和条件对石油碱渣中硫化物去除率、酚去除率和COD变化率的影响。采用正交实验方法确定了CO2中和法处理石油碱渣的最优工艺条件为：温度95℃，时间150min，CO2体积分数80%。以CuO作为除硫沉淀剂，对石油碱渣的除硫效果明显，硫化物去除率达到98%.

| Abstract: | Residual alkali, sulfides, phenols and naphthenic are contained in refinery alkaline residue, which can be removed by carbonization method. The effects of carbonization factors on the removal ratio of sulfides and phenols, and the rate of COD change from the alkaline residue were investigated. Orthogonal test design was adopted to obtain the optimal conditions in refinery alkaline residue treatment. The results showed that the optimized conditions of carbonization were temperature of 95℃, time of 150 min and the CO2 volume fraction of 80%. CuO was used as a desulphurization agent to remove the sulfur from refinery alkaline residue, and removal ratio of sulfides could reach 98%. |
