摘要
考察了醇氨法脱酸工艺的反应温度、反应时间、溶剂组成等对产品质量的影响。在脱酸和石油酸回收过程中分别使用了不同的破乳剂，结果表明：使用本工艺得到的石油酸，其纯度达到８３．７％，但是其纯酸值和粗酸值较低，还要对大分子量石油酸的应用进行专门研究。
Effects of the reaction temperature, reaction time and solvent composition of the deacidifyingprocesses of the vacuum cut 3 distillate oil with a isopropyl alcohol - ammonia - water mixed solvent on productsquality were investigated, with different demulsifying agent in deacidifying processes and the reclaiming processesof petroleum acid. The results showed that the purity of the obtained Petroleum acid reaches 83. 7 %, but its pureacid number and crude acid number are lower. So, the application of petroleum acid of bigger molecular weightshould be studied specially.
