Several heavy oil hydrogenation processes using SBCRs are developing, including VEBA CombiCracking, CANMET, Hydrocracking Distillation and Hydrotreating (HDH), M-Coke, Aurabon TERVAHL C and HC 3 processes. This is due to SBCRs' numerous advantages such as, reasonable interphase mass transfer rate at low energy input, high selectivity and conversion per pass, excellent heat transfer, better temperature control (isothermal operation), and high online factor. In addition, they require low maintenance due to their simple construction and absence of moving parts.

A mixture of n-heptane and a small amount of No. 6 fuel oil was employed as agglomerant. The experimental conditions were selected following a central composite design and regression models were developed to relate the Btu recovery and inorganic sulfur rejection to the operating variables. From the response surfaces constructed with the regression models, it was found that the Btu recovery was poor when the agglomerant/coal weight ratio was lower than 0.3. It was also found that the slurry pH did not have significant effect on the process performances.

The LICADO process relies on the relative wettability of ''clean coal and mineral particles with liquid CO/sub 2/ and water, respectively. When liquid CO/sub 2/ is dispersed into a coal-water slurry, it tends to form agglomerates with the clean coal particles and float them to the liquid CO/sub 2/ phase. The mineral particles, on the other hand, remain in the aqueous phase as refuse. Since the surface/interfacial properties of fine coal particles play such an important role in this coal cleaning operation, an understanding of their behavior becomes indispensable. Therefore, basic measurements must be made on the surface/interfacial properties of coal particles under conditions similar to those encountered in actual operation of the LICADO process.

The methods used to measure these parameters can be classified into two categories: local measurements with physical techniques such as light scattering and reflection techniques, photographical and electrical and electrochemical techniques, and global measurements with chemical techniques. Each method has its advantages and its drawbacks. Let us describe and comment them and give some data with a major emphasis on packed columns and trickle-bed reactors, mechanically agitated reactors, bubble columns, spray towers, jet reactors and plate columns.

The objective of the model is to predict the overall absorber gas-liquid internal flow profiles within the complex packing geometry, while accurately predicting the hydrodynamic parameters, such as liquid holdup and pressure drop. The gas-solid and gas-liquid drag coefficients were fitted and validated using the following experimental data by Green et al. (2006. “Hydraulic Characterization of Structured Packing via X-ray Computed Tomography”; 2007. “Novel Application of X-ray Computed Tomography: Determination of Gas/liquid Contact Area and Liquid Holdup in Structured Packing.” Industrial & Engineering Chemistry Research 46: 5734–53.): dry pressure drop, irrigated pressure drop, and liquid holdup. The validated CFD model was used to study the effect of liquid distribut...

These reactors are widly used: in petroleum industries, hydrodesulfurization, hydrocracking of heavy or residual oil-stocks, hydrofinishing or hydrotreating of lubricating oils, demetallization, denitrification of gas-oils, isomerization of cyclopropane and hydrogenation of benzene and of naphthenic lube oil distillate (30, 31, 26, 6, 32). in chemical processing, syntheses of butynediol from aqueous formaldehyde and acetylene, selective hydrogenation of acetylene to remove it in the presence of butadiene in C4 hydrocarbon streams (31), and hydrogenation of glucose to sorbitol (6). in the fight against environmental air and waste water pollution by aerobic bacterial action (6). in biological and pharmaceutic industries.

CO and N, as single gases, and a HS/N gaseous mixture were used in the experiments. The solubilities of HS and CO were found to increase with pressure and decrease with temperature within the experimental conditions used. The HS solubilities in the ionic liquid (IL) were greater than those of CO within the temperature range investigated (300-500 K) up to a HS partial pressure of 2.33 bar. Hence, the IL can be effectively used to capture both HS and CO from dry fuel gas stream within the temperature range from 300 to 500 K under a total pressure up to 30 bar. The presence of HS in the HS/N mixture created mass-transfer resistance, which decreased k{sub L} values for N. The k{sub L} and x...

Morsi Badie. 2016. “CFD Modeling with Experimental Validation of the Internal Hydrodynamics in a Pilot-Scale Slurry Bubble Column Reactor.” International Journal of Chemical Reactor Engineering 14(2):599–619), was used to predict the effects of spargers design and internals configuration on the local hydrodynamics and flow structure in a pilot-scale (0.3-m ID) and a large-scale (10-m ID) Slurry Bubble Column Reactors (SBCRs), operating under Fisher-Tropsch (F-T) process conditions. In the pilot-scale SBCR without internals, the 6-arms spider created small/fast liquid recirculations in the vicinity of the sparger and slow/large liquid recirculations at about 1.2 times reactor diameter, whereas, the 3-concentric-rings and perforated plate spargers created slow/large recirculations throughout the reactor. In the pilot-scale SBCR with internals, spargers with downward-pointing orif...
