本文叙述了用硫酸中和法处理电精制碱渣,回收环烷酸和石油系粗酚的原理及工艺流程。重点介绍了为解决回收的环烷酸质量差、有臭味等问题所开发的环烷酸精制工艺。一、碱渣来源和组成我厂来自初馏塔顶、常压塔顶和常一、二、三线以及催化汽油、催化柴油等各种油品碱洗液经电精制装置每年产生各种碱渣
This paper describes the principle and process of treating the refined alkali residue with sulfuric acid and recovering naphthenic acid and petroleum crude phenol. The naphthenic acid refining process developed to solve the problem of poor naphthalene recovery, odor and other problems was introduced. First, sources and composition of the caustic soda I plant from the top of the overhead, atmospheric top and often the first, second and third line and catalytic gasoline, diesel and other catalytic oil alkaline washing liquid generated by the electrical refining device every year a variety of caustic
