Fluidized catalytic cracking (FCC) is the most used process for converting heavy oil into more valuable fuels and chemical products such as gasoline propylene. A three-dimensional reactive gas–particle CFD model was built to study hydrodynamics, heat transfer, reaction behaviors within an industrial FCC riser reactor. The multiphase particle-in-cell methodology (MP-PIC) simulate hydrodynamics. four-lump kinetic selected represent network in model. Hydrodynamics, heat, reactions interplay...
Plastic waste gasification is one of the most promising techniques to use nondecomposable solid and produce syngas. A CFD-based Equivalent Reactor Network (ERN) model was developed for simulation polyethylene in a designed pilot-scale conical spouted bed gasifier. The ERN established through two steps: (i) hydrodynamics simulations with CFD software (ii) equivalent reactor network built Aspen Plus simulator reactions taken into account external FORTRAN modules. predictions were very good...
Modeling description of riser reactors is a highly interesting issue in design and development fluid catalytic cracking (FCC) processes. However, one the challenging problems modeling FCC that sophisticated flow-reaction models with high accuracy require time-consuming computation, while simple fast computation result low-accuracy predictions. This dilemma requires new types coupled models, which should own time-efficient acceptable model accuracy. In this investigation, an Equivalent...
An experimental setup and a three-dimensional computational fluid dynamics (CFD) model are developed for light alkane (pure propane, iso-butane, n-butane, their mixtures) dehydrogenation reactor that is key part of pilot-scale circulating fluidized bed (CFB) apparatus. Experimental findings indicate the reaction temperature (T) gas hourly space velocity (GHSV) have significant influence on process different alkanes. As propane under optimal conditions T = 600 °C GHSV 2350 h–1, conversion...
To determine the incidence and intensity of household impoverishment induced by cancer treatment in China.Average income daily consumption per capita households out-of-pocket payments for care were estimated. Household was determined comparing against Chinese poverty line (CPL, US$1.2) World Bank (WBPL, US$1.9) 2015. Both pre-treatment post-treatment consumptions calculated assuming that would divert money to pay treatment.Cancer patients diagnosed initially from 1 January 2015 31 December...
Fluidized catalytic cracking (FCC) is the most used process for converting heavy oil into more valuable fuels and chemical products such as gasoline propylene. The conventional steady state dynamic models that have commonly been to study FCC units assume simple plug flow in riser reactor two-region (i.e., freeboard dense bed)—two-phase bubble phase emulsion phase) catalyst regenerator. As a remedy limited accuracy yielded by assumptions, an integrated model based on equivalent network (ERN)...
Biomass tar as a byproduct during the gasification process can lead to many problems, such condensation and subsequent plugging downstream. However, knowledge of correlations between formation conversion gas–solid hydrodynamics in fluidized bed gasifiers (FBGs) is still limited compared other aspects biomass gasification. In this study, three-dimensional comprehensive model that simultaneously coupled detailed kinetics homo- heterogeneous with multi-phase particle-in-cell was constructed for...
Modeling Fluid Catalytic Cracking (FCC) riser reactors is of significance to FCC unit control, optimization and failure detection, as well the development design new reactors. Under guidance catalytic reaction mechanisms demands for commercial production, a ten-lump kinetic model was developed TMP process in this study. The feedstock products were divided into ten lumps by reasonably simplifying network, including heavy oil, diesel gasoline olefins, aromatics, saturates, (butane + propane),...
Understanding complex two-phase flow in gas–solid fluidization is crucial to the optimal design, rational scale-up, steady operation, and real-time control of a fluidized bed reactor. In this work, novel approach based on network theory developed characterize regime transition nonlinear fluid dynamics bed. The constructed (FRCN) consists 56 nodes, with each featured by 14 quantities that are extracted from simultaneous time-domain, frequency-domain, state-space analyses in-bed pressure time...
The double bond isomerization of 2-butene to 1-butene.
The refined utilization of various parts hybrid residual C4 has received increasing attention, but the mixed is difficult to separate due complex components and close boiling points. This paper proposes an innovative separation method using extractive distillation by adding cuprous chloride ethanolamine (C2H7NO–CuCl) into conventional extractant, as a complexing agent. vapor–liquid equilibrium (VLE) data were measured for six different systems, namely, C4–dimethylformamide (DMF) system...
