WebOct 22, 2015 · In iron and steel refining, mass transfer is always a multiphase phenomenon. Different situations occur, depending on the phases involved, as follows: Liquid–liquid mass transfer, in the case of reactions involving liquid hot metal and steel and slag. Liquid–gas mass transfer, when a gas is injected into or onto liquid hot metal and …
WebSep 28, 2024 · After the flow field in the Taylor unit becomes stable, the mass transfer module is activated to examine the mass transmission process of the gas phase to the liquid phase in the unit. The mass transfer model only applies to a two-dimensional uniform grid, so the transverse and longitudinal ratio of the grid is 1 by uniform division. WebJan 20, 2024 · Existing process operation data from a bubble column hint at a mass transfer limitation of the gas-liquid reaction. In the project, a jet loop reactor (JLR) is chosen to increase the specific interfacial area between gas and liquid, and thus increase mass transfer, while keeping the reactor system mechanically simple and low-maintenance.
WebExpressing inlet and outlet mass transfer rates of the catalytic membrane, the mass transport process, in two external fluid phases, can be separately investigated. The mass transfer rates across a catalytic membrane are analyzed in detail in other chapters of this study for both diffusive and diffusive/convective transport accompanied by ... WebMass transfer is any process in which diffusion plays a role. The molar flux is just the molar flow rate, F A, divided by the cross sectional area, A C, normal to the flow. W A = F A /A …
