Embodiment Construction

[0028] The gas phase-liquid phase absorption membrane separation and purification method of the present invention is: after the mixed gas to be treated is filtered and dedusted, it is compressed to 0.1MPa~1.0MPa by an oil-free compressor, and enters the gas phase-liquid phase membrane separator through the gas phase pipeline. . The gas phase passes through the gas phase side of the separation membrane, and the liquid phase absorbent flows through the other side of the separation membrane. The mixed gas that can pass through the separation membrane tube and can be dissolved in the liquid phase absorbent is absorbed by the liquid phase absorbent. , remove. It is not easy to pass through the separation membrane layer, and the gas that is hardly soluble in the liquid-phase absorbent stays on the gas-phase side to be purified and concentrated. The liquid-phase absorbent flows into the regeneration tower. According to the characteristics of the liquid-phase absorbent, the gas absor...

Abstract

The invention relates to a separator and a separation and purification method of a gas-liquid phase absorbing membrane. The gas-liquid phase absorbing membrane is separated by utilizing different under penetration rates of membrane materials to different substances and different solubilities of liquid phase substances at the penetration side of the membrane to different substances and increasing the contact area of the gas-liquid phase under the dual functions of preferential penetration and selective absorption so that the purpose of purification is achieved. The technical scheme has the advantages of less equipment investment, high separation efficiency, high purity of separated gas, split-phase operation and separation of the gas-liquid phase and no secondary pollution, and is especially suitable for separating and removing CO2, H2S, and the like in petrochemical gas, combustible flue gas and marsh gas.

Description

technical field [0001] The invention relates to a separation device and separation and purification technology for mixed gas, specifically a device and technology for separating mixed gas developed on the basis of the selective permeation characteristics of membranes to molecules and the solubility of absorbing liquids to different substances. Separation and removal of CO from petrochemical gas, combustion flue gas and biogas 2 and H 2 S gas etc. Background technique [0002] At present, the commonly used separation and purification technology methods at home and abroad include: solvent absorption method, solid adsorption method (including pressure swing adsorption) and membrane separation method. Taking anaerobic fermentation biogas as an example, the main component of biogas is CH 4 55% to 70%, CO 2 30% to 45%, and 2% to 4% H 2 O, a small amount of H 2 S, N 2 Wait for gas. The pressure swing adsorption method uses molecular sieves as the adsorbent. Under the action...
