Hygroscopic water is adsorbed on the surface of soil particles and is difficult to be utilized by plants. 在土壤中,水以不同形式存在。有重力水,它是在重力作用下迅速通过土壤大孔隙排出的水。毛管水是靠毛管力保持在土壤孔隙中的水,是植物可利用...
If there is a level control failure and the liquid dump valve is open, the gas entering the vessel will exit the liquid outlet line and would have to be handled by the next downstream vessel in the process. Unless the downstream vessel is designed for the gas blowby condition, it can ...
Process for contacting gas, liquid and solid particles in a reactor 1 comprising a) introducing gas through inlet 2 and liquid through inlet 3 into the lower part of the reactor 1 and introducing solid particles into the upper part of the reactor 1 through inlet 7;b) passing gas and ...
In this paper, the gas injection process and its challenges were investigated. Then the overcoming methods of these challenges were investigated. To inhibit asphaltene deposition during gas injection, the use of nanoparticles was proposed, which were examined in two categories: liquid-soluble and gas...
pressure, which can be obtained through different test methodsbubble point valueanddiffusion flow. These test methodsalso suitable for hydrophobic gas filters, usinglow surface tension liquid (commonly used alcohol solution)wetting it, the corresponding bubble point and diffuse flow tests can be carried...
Hydrodynamics of multiphase flow in a trickle-bed filled with small particles under the supercritical condition Jian Jin, Zhen-Min Cheng, Jing-Gang Li, Si-Cao Wu Pages 69-73 select article A novel approach for simultaneous hydrodynamic characterization of gas–liquid and gas–solid systems ...
Solid–liquid–gas reactions are ubiquitous and are encountered in both nature and industrial processes1,2,3,4. A comprehensive description of gas transport in liquid and following reactions at the solid–liquid–gas interface, which is substantial in regard to achieving enhanced triple-phase reaction...
The present work studies particle resolved simulations of liquid/solid and gas/solid fluidization in a cuboid domain with periodic lateral boundary conditions. The focus is on investigating particles' dynamics, while a particular care is devoted to the spatial grid resolution and statistical time conver...
Gas-liquid interfacial area and liquid-side mass-transfer coefficient in a slurry bubble column Influences of suspended particles upon such parameters as gas holdup, volumetric liquid-state mass-transfer coefficient, and gas-liquid interfacial area in... E Sada,H Kumazawa,CH Lee,... - 《Industr...
When spraying a flammable liquid, a mist can form consisting of very small droplets with a very large overall surface area. These mists can explode and in cases of fine mists a flash point is formed, as discussed in Clause 3.1.1. Flash points for mists are not that important because ...
