摘要: 提高能源利用效率、减少CO2排放是促进石化企业高质量发展的关键,原油直接生产化学品技术在炼化结构转型中获得高度重视,推动石油化工行业发生革命性改变。基于原油中轻馏分油、重馏分油催化裂解反应特性的差异,开发了分区耦合转化工艺和原油催化裂解专用催化剂,形成了原油催化裂解生产化学品(CCPP)技术。扬州石化有限责任公司采用该技术对原油预处理塔和重油选择性催化裂解装置进行了工艺适应性改造以及工业试验。结果表明:采用CCPP技术加工江苏油田原油,化学品产率高达50.99%,与同样以生产低碳烯烃为目标的炼化一体化炼油厂相比,在化学品产率接近时,该技术生产乙烯和丙烯的成本可降低46.4%,CO2排放量可降低30.7%。

Abstract: Improving energy efficiency and reducing CO2  emission are the keys to promote the high-quality development of petrochemical industry. Crude-to-chemical has been highly valued in the transformation of refining and chemical structure, which has promoted revolutionary. Crude cracking pyrolysis process (CCPP) is a crude-to-chemical technology. Based on the difference of catalytic cracking reaction characteristics between light and heavy fractions in crude oil, a multi-zone coupling reaction process and a specialized catalyst for CCPP were developed, and the crude oil pretreatment column and maximum catalytic propylene (MCP) unit were reformed. Industrial trial of CCPP technology was carried out in Yangzhou Petrochemical Company. The results showed that the chemical yield of crude oil from Jiangsu oilfield processed by CCPP technology was as high as 50.99%, the production cost of ethylene/propylene could be reduced by 46.4%, and the CO2 emission could be reduced by 30.7%.
