Abstract:

In this paper, the harmless treatment technology of chemical distillation stills and hazardous wastes, and the specific resource utilization schemes and approaches of chemical distillation stills with different types and properties were reviewed. From the point of engineering application, the application range, advantages and disadvantages, technical status and development direction of different harmless treatment technologies for distillation reactor residues were described and analyzed. According to the composition and physical properties of different rectification still residues, the resource utilization scheme of different kinds of rectification still residues was summarized. On this basis, in view of the phenol-based distillation residue with large output and complex components, a diversified resource conversion and harmless treatment plan for the light and heavy components of the distillation residue was proposed, and a comprehensive analysis and development thinking were carried out on the utilization technology of residual resources in distillation residues.

Key words: distillation, residue, organic waste, useless treatment, conversion

摘要:

综述了化工精馏釜残危废的无害化处理技术以及不同种类及属性的化工精馏釜残特异的资源化利用方案和途径。从工程应用角度阐述和分析了精馏釜残不同的无害化处理技术的使用范畴、优缺点、技术现状和进展方向。根据不同精馏釜残的成分及物性特点,总结了不同种类精馏釜残的资源化利用方案。在此基础上针对目前产量大且组分复杂的酚基精馏釜残,提出对精馏釜残轻重组分进行多元化资源转化与无害化处理方案,并就此进行了综合分析,对精馏釜残资源化利用技术进行了初步的思考。
