Abstract

The invention discloses a gas-liquid absorption-reaction kinetic studying device. A measuring device mainly comprises a wetted-wall column absorber, a constant temperature controller and a gas chromatographic analyzer, and is used for measuring the reaction rate constant of a gas-liquid absorption reaction. Gas flows through a flow meter to the constant temperature controller to be heated, then flows through a saturator to enter the bottom of the wetted-wall column absorber, and flows out from the upper portion of the absorber after being reacted with liquid; after the reacted gas is condensed through a condenser and dried through a drying device, one part of gas enters the gas chromatographic analyzer, and the other part of gas is directly exhausted. Firstly, the liquid is fed to a buffer tank through a peristaltic pump from a primary-liquid storage tank, and is heated through the constant temperature controller; secondly, the heated liquid enters the absorber and is reacted with the gas in a countercurrent contact mode; finally, a solvent flows out from the bottom of the wetted-wall column absorber and enters a solvent storage tank. The gas-liquid absorption-reaction kinetic studying device is simple in structure and convenient to operate, data can be collected at any moment, and the data result has repeatability.

Description

technical field [0001] The invention relates to a research device for gas-liquid absorption reaction kinetics. Background technique [0002] Gas-liquid absorption reactions have been extensively studied. e.g. CO 2 Absorption reaction with alcohol amine, H 2 Absorption reaction of S and ferric sulfate, O 2 Absorption reaction with sodium sulfite, sulfuric acid selective absorption reaction of isobutylene, etc. The study of reaction kinetics plays a vital role in the design of reactors and the prediction of reaction phenomena in the reaction process. The experimental study of kinetics can obtain the parameters of the calculation of industrial processes, and check or reveal a certain absorption model. various reaction factors. Danckwerts (McGraw-Hill, 1970) and Doraiswamy and Sharma (John Wiley, 1984) earlier proposed the mass transfer theory and model of the gas-liquid reaction system. [0003] At present, there are many experimental devices used for the study of gas-liq...
