Moghekar, Deepak (2008) Project Report On Modeling and simulation of gas-liquid interfacial area in three phase fluidized and semi-fluidized bed. MTech thesis.
Three phase systems are vital part of chemical industry,as reactions involving gas, liquid solid are often encountered in chemical process industry [Yatish Shah 2000]. The most common occurrence of this type of three phase systems is in hydro processing industry in which variety of reactions between hydrogen and oil phase and solid catalyst have been found. The other common three phase reactions are catalytic oxidation and hydration reactions These and other numerous similar gal-liquid–solid reactions are carried out in reactors. The three-phase system is subcategorized as
• Reactions where the gas, liquid and solid are either reactants or products
• Gas-Liquid reactions with solid as a catalyst.
• Two reaction phases and third as inert phase.
• All three phases are inert as found in unit operations.
Examples of first two types can be found very often in chemical process
industry, as each phase is essential in the reaction mechanism. In the third type, one
inert phase in especially added to get the advantage of three-phase system. The third
inert phase induces better momentum exchange between the phases, helps in better
distribution of reactant species and good temperature control. The filtration
operation can be example of fourth type of three phase system
