摘要: 介绍了国内外煤焦油加工发展的现状和煤焦油分离的新技术,阐述了我国在该领域存在的不足,并以PRO/Ⅱ为工具对煤焦油两塔式连续蒸馏进行了模拟研究。结果表明用PRO/Ⅱ进行模拟是改进工艺的有力工具,将模拟结果与现场数据进行比较后,发现模拟的工艺能大大改善煤焦油的分离效果,提高了萘的收率。

Abstract: The paper introduces coal tar processing and new technology of coal tar separation both at home and abroad and the shortcomings of domestic technology. PRO/Ⅱ was used to simulate two-column continuous distillation and was found to be a good tool to improve the technology. Comparing the result with actual operation, the simulated technology could greatly improve the effect of separation and increase the yield of naphthalene.
