重油中金属杂质脱除技术研究进展
发布时间：2019-04-12 16:05
【摘要】：重油的开采与加工日益成为石油化工行业关注的焦点,然而其深加工利用受到内部高含量金属的影响。为此,本文介绍了重油中金属的来源、存在形态及其对石油加工利用的危害。综合对比分析了国内外重油脱金属常用的几种方法。膜分离法虽然工艺简单、经济环保,但该技术不成熟,难以满足工业应用;催化加氢法金属脱除率高,但易受氢源及催化剂性能限制,且工业成本较高;化学法易于操作但副反应多且易污染环境;超声波脱金属法节能降耗明显,脱金属率高,但大型的超声装置如何应用于工业生产,尚需进行深入研究;微生物法投资少,适应性强,但难以筛选合适的菌种。总之,由于重油自身的特性,单一的脱金属技术难以获得佳绩,联合脱金属将成为一种发展趋势。
[Abstract]:The exploitation and processing of heavy oil has become the focus of attention in petrochemical industry. However, the deep processing and utilization of heavy oil is affected by the internal high content of metals. In this paper, the sources and forms of metals in heavy oil and its harm to petroleum processing and utilization are introduced. Several commonly used methods of heavy oil demineralization at home and abroad are compared and analyzed. Although the process of membrane separation is simple, economical and environmentally friendly, the technology is not mature and difficult to meet the industrial application, the metal removal rate of catalytic hydrogenation process is high, but it is easily limited by hydrogen source and catalyst performance, and the industrial cost is high. The chemical method is easy to operate but has many side effects and pollutes the environment, the energy saving and consumption reduction of ultrasonic demineralization method is obvious, and the rate of demineralization is high, but how the large ultrasonic device is applied to industrial production still needs to be studied in depth. Microbiological method has little investment and strong adaptability, but it is difficult to screen suitable bacteria. In a word, due to the characteristics of heavy oil, it is difficult for single demineralization technology to achieve good results, and joint demineralization will become a trend.
