【摘要】：全白土催化剂具有高活性、高稳定性以及优异的抗重金属(镍、钒)污染能力,具有较强的重油转化和降低汽油烯烃的能力。使用该产品复配的催化裂化催化剂,可以进一步优化炼油装置产品结构,增加装置生产灵活性,提高炼油企业利润空间。本文针对兰州石化公司新建一套2万吨／年全白土催化剂装置的可行性进行研究,该项目采用原位晶化法制全白土催化剂制造工艺,通过采用最新的催化剂生产工艺及技术,生产LB-5型分子筛产品。LB-5催化剂具有较高的活性和稳定性,尤其具有很强的抗钒等重金属污染能力,适用于加工重油、渣油原料等品质较差的原料,提高重油转化率及降低催化剂结焦等性能。论文基于文献调研及相应的市场分析,确定了项目装置规模和产品类型。通过对该项目涉及的关键工艺技术选择、工艺安装方案、设备、自控水平、附属设施、原辅料供应、节能、环保、安全措施等全方位的可行性研究和分析,在此基础上,对项目进行了技术经济评价,通过运用不确定性分析法分析,确定项目盈利能力。总体研究结果表明,虽然项目存在一定的风险和问题,但该该项目是可行的。
[Abstract]:Full-clay catalysts have high activity, high stability and excellent resistance to heavy metal (nickel, vanadium) pollution. It has strong ability to convert heavy oil and reduce olefin in gasoline. The product structure of refining unit can be further optimized and the flexibility of unit production can be increased by using the FCC catalyst which is mixed with this product. In this paper, the feasibility of building a new 20,000 t / a clay catalyst plant in Lanzhou Petrochemical Company is studied. The project adopts in situ crystallization to produce the whole clay catalyst. By using the latest catalyst production process and technology, the production of LB-5 zeolite product. LB-5 catalyst has higher activity and stability, especially has a strong resistance to heavy metal pollution, such as vanadium. It is suitable for processing poor quality raw materials such as heavy oil and residuum, improving conversion of heavy oil and reducing coking of catalyst, etc. The paper is based on literature investigation and market analysis. Through the project involved in the key process technology selection, process installation scheme, equipment, automatic control level, ancillary facilities, raw and auxiliary materials supply, energy saving, environmental protection. Based on the comprehensive feasibility study and analysis of safety measures, the technical and economic evaluation of the project is carried out, and the profitability of the project is determined by using the uncertainty analysis method. The overall research results show that. Although the project has certain risks and problems, the project is feasible.
