2) acid removal
脱酸
1.
Experimental research on thermal acid removal of high-acid crude oil;
高酸原油热脱酸实验研究
2.
In the paper experiments on acid removal behavior about nano-titania solution were carried out.
本文对纳米TiO2分散体系进行了加热、加碱和加分散剂后再加碱脱酸,从试验结果可知,加热脱酸是比较经济实用的,但是脱酸的效率不是很高;加碱脱酸很快就能达到中性,但是加碱后纳米TiO2的分散性及其稳定性变差;试验还发现先加入一定量的分散剂再加碱,既能达到脱酸的目的又能不影响其分散效果。
3.
The processes employed for processing the highly acidic crudes in domestic and overseas refineries in recent years have been discussed and such processes for acid removal and their technical routes like caustic neutralization, extraction, absorption, chemical conversion, hydrogenation, and thermal pyrolysis etc .
综述了近年来国内外高酸原油的加工方法,并对碱中和、抽提、吸附、化学转化、加氢、热分解等脱酸方法及其技术路线进行了比较,指出加氢脱酸是较为彻底且无公害的方法,但投资较高;热加工法由于方便可行且成本较低,越来越受到更多的关注。

补充资料：碱炼脱酸
分子式：
CAS号：
性质：毛油的主要化学脱酸方法。用烧碱处理可以几乎完全脱除油脂中的游离脂肪酸，使其转化为不溶于油的皂脚。其他酸性物质同样可以和碱化合而进入皂脚中。生成的皂脚可以从油中吸附一些杂质如磷脂、色素、蛋白质、胶质等使之同时从油中除去。脱酸的方法有间歇碱炼、离心机连续碱炼、物理精炼和泽尼斯碱炼等。
