This paper presents an integrated refinery scheduling model and its applications for a refinery located in Jiujiang, Jiangxi, P.R.China. The model integrates a crude oil unloading and storage area, a refining area, a blending area and a product storage area of the refinery. The scheduling model can be applied for optimizing the operation, configuration and production schedule of the refinery. T...

Mesoporous high-silica zeolite Y with advantages of improved accessibility acid sites and mass transport properties is highly desired catalytic materials for oil refinery, fine chemistry emerging biorefinery. Here, we report the direct synthesis mesoporous (named MSY, SiO2/Al2O3 ? 9.8) their excellent cracking performance. The obtained MSY are single crystals octahedral morphology, abundant mes...

Artificially mimicking aging of an equilibrium catalyst (ECAT) is effective strategy to model the deactivation a Fluid Catalytic Cracking (FCC) during refinery operations. Herein, we have used correlative microscopy approach unravel inter-particle spatial heterogeneities in artificially deactivated catalysts (DCATs) and compared them with real-life ECAT containing on average 3800 ppm Ni 2300 V,...

The catalytic cracking method of PAHs for the pyrolysis gaseous products is proposed to control their pollution to the environment. In this study, the Py-GC-MS is used to investigate in situ the catalytic effect of CaO and Fe2O3 on the 16 PAHs from Pingshuo coal pyrolysis under different catalytic temperatures and catalyst particle sizes. The results demonstrate that Fe2O3 is effective than tha...

Due to the involvement of hazardous materials and potential serious accidents that may occur in petrochemical plants, it is great significance develop real-time state evaluation methods offering high performance. Data-driven have received widespread attention following development advanced condition-monitoring systems. However, scarce training samples evaluated under multiple operating conditio...

In this article, we use a genetic algorithm to obtain an economically optimal preventive maintenance frequency for different equipment, the parts inventory policy (number and type of spare parts to keep in stock), and labor allocation in process plants. To assess cost, we improved a previously published Monte Carlo simulationbased maintenance model (Nguyen et al. Ind. Eng. Chem. Res. 2008, 47(6...
