直馏汽油和碳四馏分非临氢改质技术是近年来增产汽油、提高产品辛烷值的新工艺。但是由于碳四馏分中含有较多烯烃,其聚合反应较多,反应放热剧烈,反应器温升无法控制,为解决反应放热问题,扬州石油化工有限责任公司(以下简称扬州石化)对碳四线进行了改造。本文阐述了扬州石化直馏汽油和碳四馏分改质装置改造前后装置运行情况。 相似文献

Abstract Magnetic separation has been historically active in several different industries, yet has not been utilized in petroleum refining until recently. Development of economical permanent magnets with high magnetic strength has led to a new process known as MagnaCat®. The MagnaCat® Process separates less active (high metals) particles catalyst from equilibrium Fluid Catalytic Cracking (FCC) catalyst, producing a higher activity/lower metals catalyst for recycle. Pilot FCC studies showed lower hydrogen, dry gas, and coke make with higher wet gas and octane from catalyst separated by MagnaCat®. With the use of a MagnaCat® Process unit, a refiner would produce an economic advantage of $0.20 to $0.40/Barrel of FCC charge and enhance unit operability. 相似文献

The current trend for processing more aggressive crude oils has resulted in a considerable increase of corrosion and hydrogen
damage at Fluid Catalytic Cracking Units in Brazil. Therefore, it was proposed a new method for on-line and real time corrosion
monitoring: evaluation of the integrity of the iron sulfide film by the voltammetric technique. This methodology would allow
one to detect and inhibit the destruction of the sulfide layer by cyanide ions before a significant amount of hydrogen is
generated and permeates the steel. Therefore, the lifetime of industrial equipment would be considerably improved. The feasibility
of the proposed methodology was validated through bench scale tests. 相似文献
