介绍了采用脱酸剂 S 对直馏柴油进行脱酸精制方法,结果表明,当原料酸度为20.00 mgKOH/100 mL 时,S 剂的加入量为400 μg/g 即可,S 剂的加入量应随原料油酸度而变化;精制脱酸油的酸度应以尽量接近0为宜。对采用脱酸剂 S 精制柴油的效果进行评价,结果表明,对成品柴油质量无不良影响,在柴油罐底水中加入3%的抗乳化剂 A 和0.2%抗酸度回升剂 E 可解决脱酸油乳化及遇水酸度回升问题。直馏柴油无碱脱酸成本简要概算为2.922元/t 油。
The deacidification method of straight-run diesel was introduced by using deacidification agent S, the results showed that when the acidity of raw material is 20.00 mgKOH / 100 mL, the dosage of S agent is 400 μg / g, the addition amount of S agent should be With the acidity of the feedstock changes; acid deacidification should be as close to 0 as appropriate. The results of using deacidification agent S to refine diesel oil showed that there was no adverse effect on the quality of the finished diesel oil. The addition of 3% anti-emulsifier A and 0.2% anti-acidity booster E at the bottom of diesel tank could solve the problem of deacidification oil Emulsification and water acidity recovery problems. Straight-run diesel alkali-free acid costs a brief estimate of 2.922 yuan / t oil.
