Dual – Drive Stirring Gas – Liquid Mass Transfer Coefficient Determination Experiment Device
The main feature of the dual-drive stirred absorber is that the stirring of the gas phase and liquid phase is independently controlled, with stirring speeds that can be individually adjusted, thus providing broad adaptability. By varying the rotational speeds of the gas and liquid phases, the absorption rate can be measured to determine its mass transfer mechanism; alternatively, by adjusting the concentration of the liquid or gas phase, the mass transfer rate on the gas film side or the liquid film side can be determined.
Ethyl Acetate Synthesis Practice Device
Ethyl acetate is a fine chemical product with extensive applications. It exhibits excellent solubility and quick-drying properties, making it a versatile material. As a crucial organic chemical raw material and an outstanding industrial solvent, it is widely used in the production processes of cellulose acetate, ethyl cellulose, chlorinated rubber, vinyl resin, cellulose acetate resin, synthetic rubber, coatings, paints, and other products. The synthesis process of ethyl acetate involves multiple chemical engineering operation units; therefore, developing a teaching device for an ethyl acetate production line holds significant practical importance for practical training teaching in vocational colleges and higher education institutions.
Ethylbenzene Dehydrogenation Experimental Device
Through this device, students can master the structure and process flow of gas-solid catalytic experimental devices; they can also master the determination and evaluation of the activity of iron oxide-based catalysts, and regenerate deactivated catalysts by activating with steam to remove coke.
Experimental Device for Determination of Residence Time Distribution and Reactor Flow Characteristics
Through this device, students can learn the methods of measuring residence time in continuous stirred-tank reactors (CSTRs) and tubular reactors; understand how the parameters of the series model characterize the residence time distribution (RTD) of the CSTR and the degree of backmixing, as well as the physical meaning of model parameter N; and comprehend the two ideal flow patterns: plug flow and perfect mixing.
