PURPOSE:To separate compositions from a gas with high efficiency by installing in an expansion chamber a partition wall that separates the compositions, which are collected on the side of the ferromagnetic field of a magnetic gradient, from other compositions and discharging them. CONSTITUTION:The gas taken in from a gas inlet 1 is compressed to several ten atmospheric pressures by means of a compressor 2, and the compressed gas is cooled by a radiator 3. Then the compressed gas is further cooled by passing the gas through the trap of the primary side of a heat exchanger 8, and simultaneously moisture that condenses on the side of comparatively high temperature is removed. And then, when an expansion turbine 5 is revolved by means of a kinetic energy from the compressed gas and simultaneously the compressed gas is led to the expansion chamber 11 of a fractional distiller 7 and adiabatically expanded, the temperature of the gas further goes down by Joule-Thomson effect. The fractional distiller 7, having the expansion chamber 11, is provided with the magnetic gradient by a magnet 6 toward the center of the chamber. Because of this magnetic gradient, the compositions having high magnetic susceptibility in the compressed gas are attracted to the magnet 6 and are efficiently separated. |
