| 摘 要： | 针对直馏柴油纤维膜接触器脱酸技术的不足，采用西南石油大学研制的绿色脱酸剂对中国石油克拉玛依石化公司生产的直馏柴油进行脱酸试验；采用水解法对废脱酸剂进行再生，同时得到石油酸副产品。结果表明：在绿色脱酸剂中有机胺质量分数为15%、剂油体积比为0.3、反应温度（相分离温度）为40 ℃、相分离时间为80 min的条件下，脱酸剂有效循环次数达到13次；废脱酸剂在再生温度为90 ℃、再生时间为8 h、溶剂油用量为4 mL/g的条件下进行高温水解再生，得到的再生脱酸剂用于柴油脱酸的有效循环次数可达12次；回收的石油酸的粗酸值达到205.5 mgKOH/g，满足一级品75号酸的质量标准要求(SH/T0530-1992)。纤维膜接触器绿色脱酸工艺完全消除乳化现象，脱酸剂可再生和循环使用，无三废排放。

| Abstract: | The application of green deacidification agent(GDAA,developed by Southwest Petroleum University) in the fiber membrane contactor deacidification technology treating straight run diesel fraction from Karamay Petrochemical Company is carried out,as well as the hydrolysis regeneration of spent agent.Results show that the application of GDAA makes up the deficient of single fiber membrane contactor deacidification technology for diesel fuel;in this combination,no acid emulsion and waste discharge,the GDAA can be pyrohydrolysised and recycled.Under the conditions of a mass fraction of organic amine in GDAA of 15%,GDAA/oil volume ratio of 0.3,a reaction temperature(phase separation temperature) of 40 ℃ and a phase separation time of 80 min,GDAA can be recycled effectively for up to 13 times.Spent GDAA can be pyrohydrolysised under the condition of a solvent oil amount of 4 mL/g,a regeneration temperature of 90 ℃ and a regeneration time of 8 h,the regenerated GDAA can be reused for treating diesel oil effectively up to 12 times.As a byproduct,the recovered petroleum acid has a raw acid number of 205.5 mgKOH/g,which meets the requirement of first class 75#acid specifications(SH/T 0530—1992). |
