Analysis of Current Status of Steam Cracking Feed Production and Measures for Maximization of Steam Cracking Feed

In recent years China has seen speedy development of its ethylene industry. Compared to other advanced countries the per capita ethylene consumption in China is still low. With successive startup of grassroots ethylene projects in China after 2006 and debottlenecking and expansion of existing ethylene units China will be confronted with the major issues related with increase of feedstocks for steam cracking. Naphtha is the main feedstock for producing ethylene, and the hydrocracked tail oil is increasing its share in the steam cracker feedstock pool over recent years. This article has analyzed the possibility for maximization of steam cracking feedstock and estimated steam cracker feedstock output based on processing 5 Mt/a of different crudes including the mixed crude transferred through Lu-Ning pipeline and Arabian light crude using corresponding process technologies at the refinery.     

Overview on Routes for Development of China''''s Petroleum Refining Technology

China has formed a complete and packaged system of domestic petroleum refining industry. Till 2020 the demand for petroleum products in China will record a sharp growth. However, China is currently confronted with a shortage of oil resources, unsatisfactory quality of petroleum products, a widening gap between demand and supply of steam cracking feedstocks, and a stern situation in environmental protection. In this context the petroleum refiners of China, while taking into account the actual conditions, should seek for the way of deep processing to produce transportation fuels and chemical feedstocks that can hardly be replaced by other energy forms, continue to bring into full play FCC process as core process for making finished oil products, speed up the development of hydrocracking to achieve integration between refining and chemical production, adopt measures that can combine feedstock pre-treatment, novel FCC technologies and after-treatment of products to improve the quality of finished products, as well as realize the recycling of wastewater and control over air pollution caused by SOx to accelerate the development of petroleum processing industry in China.

重油加氢处理分子层次模型构建与原料适应性考察

复杂体系反应动力学模型在石油加工过程工艺设计、操作条件优化等方面具有重要的应用价值。传统集总模型由于组成划分强烈依赖于建模所用原料,导致其原料适应性差。相比于集总模型,分子层次模型以分子作为最小构筑单元,模型的预测能力及原料适应性大为提高。笔者提出了分子层次模型构建策略,完成了重油加氢处理分子层次模型的构建,并将构建完成的重油加氢处理分子层次模型应用于不同重油原料,以考察其产物性质预测能力与原料适应性。结果表明：不同重油原料的组成模型宏观性质与实验数据一致,分子分布与高分辨质谱数据一致;反应动力学模型计算得到的产物宏观性质与分子分布符合实验结果,硫化物与氮化物的转化规律与实验规律一致。因此,分子层次模型具有一定的预测能力与原料适应性,相比于集总模型具有更高的工业应用价值。

STRUCTURAL CHARACTERIZATION OF PETROLEUM BASED FEEDSTOCKS FOR CARBON BLACK PRODUCTION

Some selected petroleum based feedstocks have been characterized by ¹H and ¹³C NMR spectroscopy for their possible use as carbon black feedstock (CBFS). Feedstocks studied are pyrolysis tars, clarified oils, aromatic extracts and vacuum residue. Analysis of average structural NMR parameters show that pyrolysis tars because of their being highly aromatic in character (high BMCI) are the most suitable feedstock for carbon black. Aromatic extracts rank the next. Clarified oils of Indian refinery origin needs further processing due to middle distillate mode refining severity.
