According to the different spraying speed of liquid and gas flow rate, the flow condition of packed tower can be divided into five kinds, which is the emulsification condition when the spraying speed and airflow speed reaches a certain value, gas, liquid, mixed violently, the formation of gas-liquid emulsion difficult to separate. The emulsification condition has the largest gas and liquid contact area, heat and mass exchange condition is the best. The operation of the packed tower of small air separation unit is best controlled in this condition.
Dear air separation small air separation unit, large air separation unit and liquid small air separation plant production of industrial gases in various manufacturing industries is indispensable, the "12th Five-Year Plan" only coal chemical industry investment amounted to about 700-800 billion yuan, and small air separation unit in coal chemical projects accounted for 5% of the market size of large air separation unit of about 35-40 billion yuan.
