利用现有催化裂化装置提高丙烯收率是一项颇具前景的经营策略。为了巩固在催化裂化技术市场中的地位,技术供应商之间开展了一系列合作,从事新技术的开发和商业化运行。利用先进的催化剂、添加剂提供低成本的解决方案,推动催化裂化技术的成功运行,如提高丙烯的收率,加工高杂质含量的重质原油,使催化裂化装置排放达标,特别是实现硫氧化物的减排。此外,采用双提升管和多反应区装置改变工艺模式,实现原料多样化。这些技术措施和解决方案,使原来主要生产汽油的催化裂化装置的灵活性更大,在提高汽油调合组分产量的同时还可选择轻循环油产量最大化和/或轻质烯烃产量最大化。可以肯定,催化裂化技术将在现代炼油企业中继续发挥重要作用。
The use of existing catalytic cracking units to increase propylene yields is a promising business strategy. In order to consolidate its position in the catalytic cracking technology market, technology suppliers have conducted a series of cooperation to develop and commercialize new technologies. The use of advanced catalysts and additives provides a cost-effective solution to the successful operation of catalytic cracking technology such as increasing the yield of propylene and processing heavy crude oil of high impurity content to meet the standards of FCCU emissions, especially the implementation of sulfur oxides Emission reduction. In addition, the use of dual riser and multi-reaction zone device to change the process mode, to achieve diversification of raw materials. These technical measures and solutions make the former FCC gasoline-based catalytic cracking unit more flexible. While increasing the yield of gasoline blending components, it is also possible to maximize the production of light cycle oil and / or maximize the production of light olefins . To be sure, FCC technology will continue to play an important role in modern refineries.
