【摘要】：石蜡一直以来都是溶剂法生产润滑油的副产品,由于我国经济长期的快速发展,石蜡产品的应用范围越来越广泛,对石蜡的需要量不断增加,特别对精炼、半精炼石蜡的需求一直旺盛不衰。中国石油化工股份有限公司北京燕山分公司(以下简称燕山分公司)是我国重要的润滑油和石蜡生产基地,其含油蜡如能有效利用,可再生产出脱油蜡10万吨以上(其中减四线脱油蜡7万吨),经济效益亿元以上。因此,提高现有蜡资源的利用率是提高石蜡产量的有效及必要的手段。燕山分公司欲充分挖掘现有溶剂法生产润滑油装置的潜力,通过对各相关装置技术改造,提高石蜡产品量,满足国内国际市场的需要,以较少投入,得到较高的效益,符合国家的产业政策。本文以中国石油化工股份有限公司北京燕山分公司酮苯装置提高蜡资源利用率及配套系统改造项目为研究对象。本项目拟在酮苯装置重油系统增加脱油单元,拟分二期进行改造,第一期改造目的是先将减二、减三蜡资源全部回收,第一期改造后再进行第二期改造是再将剩余的减四蜡资源回收利用。本文通过对该项目进行详细的可行性研究,运用项目可行性研究的相关理论进行了市场分析与预测、工程技术方案研究、生态环境影响分析、经济分析与社会评价。最后得出该项目可行的结论。
[Abstract]:Paraffin has always been a by-product of oil production by solvent method. With the rapid development of economy in China, the application of paraffin wax products is becoming more and more extensive, and the demand for paraffin wax is increasing, especially for refining. Demand for semi-refined paraffin wax has been strong. China Petrochemical Co., Ltd. Beijing Yanshan Branch (hereinafter referred to as Yanshan Branch) is an important lubricant and paraffin wax production base in China. The regenerative output deoiling wax is more than 100000 tons (including 70,000 tons of deoiling wax minus the fourth line), and the economic benefit is more than 100 million yuan. Therefore, increasing the utilization rate of wax resources is an effective and necessary means to increase paraffin yield. Yanshan Branch Company wants to fully tap the potential of the existing solvent process to produce lubricating oil units, through the technical transformation of various related units, to increase the quantity of paraffin wax products, to meet the needs of the domestic and international markets, and to obtain higher benefits with less investment. In line with national industrial policy. The research object of this paper is to improve the utilization ratio of wax resources and the retrofit of supporting system in ketone benzene plant of Beijing Yanshan Branch of China Petrochemical Co., Ltd. In this project, the deoiling unit is to be added to the heavy oil system of the ketobenzene plant, and the revamping is to be carried out in two phases. The purpose of the first phase of the transformation is to first reduce the two, reduce the three wax resources and recover all the resources. After the first phase of transformation, the second phase is to recycle the remaining four wax resources. Based on the detailed feasibility study of the project, the market analysis and prediction, the project technical scheme research, the ecological environment impact analysis, the economic analysis and the social evaluation are carried out by using the relevant theory of the project feasibility study. Finally, the conclusion is drawn that the project is feasible.
