Abstract

The present invention proposes hydrate process and apparatus for separating gas mixture continuously. The countercurrent continuous separation process in three serially connected stages is adopted to raise the CO2 recovering rate from fume, the CO2 concentration in the product and the separation rate and efficiency. Each of the separating systems consists of a hydrate synthesizer, a hydrate decomposer, a circulating pump, a heat exchanger, and a micro bubble mixing and jetting reactor. The present invention is suitable for continuous separation and enrichment of CO2 in the fume of coal burning power plant, and may be also used in the continuous separation and enrichment of gas mixture containing CO2 in chemical industry, metallurgy, petroleum and other fields.

Description

technical field

[0001] The invention relates to a continuous separation technology of mixed gas, in particular to a continuous separation technology of mixed gas by hydrate method. technical background

[0002] The reality of global warming is constantly sounding the alarm to people all over the world, and greenhouse effect gases, especially CO 2 Gas emissions have become one of the hottest issues in the world. As of the end of 2004, a total of 141 countries and regions around the world have approved to reduce CO emissions 2 The purpose of the "Kyoto Protocol", which came into effect on February 16, 2005, requires all countries to control the emission of greenhouse gases. Atmospheric CO 2 The main source of the continuous increase in concentration is the exhaust gas emitted from large-scale energy production in industry. my country is a country where coal is the main energy source, and this energy structure will not change for a long time in the future. Most of my count...
