Title:
【発明の名称】ガス混合物からのガス成分の凍結分離
Document Type and Number:
Japanese Patent JP2001522982
Kind Code:
A
Abstract:
The invention relates to a method and a device for separating a gas component in a gas mixture by freezing. The gas component to be separated has the lower vapor pressure when compared with the other gas components in the gas mixture. A working temperature is chosen at which the gas components to be separated freezes out almost completely. The partial pressure of the other gas components at working temperature is kept lower than the vapor temperature of the other gas components at working temperature. Once the components to be separated have been frozen out, the other gases are evacuated. The device comprises at least two cooling tanks. Means are provided to alternately feed the gas mixture to the cooling tanks so that a predetermined partial pressure arises in each tank.
