摘要： PURPOSE:H2O and CO2 in compressed air is absorbed and removed by a number of absorber towers. Impure N2 having pressure lower than absorption operation is used for desorption and regeneration thereby decreasing N2 amount to be used, to increase N2 recovery as product. CONSTITUTION:Air is compressed 1, cooled 2, introduced into the absorber tower 21 to remove H2O and CO2, and through the heat exchanger 32, introduced into the rectifying tower 22. Meanwhile, impure N2 from the tower 7 is introduced, through the pipe 11 and the heat exchanger 32, into the absorber tower 22 to desorb the absorber such as zeolite at a lower pressure than the absorbing operation. The tower 21 and 22 operations, air absorption and impure N2 desorption is charged by the changeover valves 23 to 30, at regular intervals. The precess drastically controls the variations of pressure and flow rate and reduces the amount of impure N2 for desorption to about 30 to 40% of air volume, thereby to increase N2 recovery coefficient to 40% or more, yielding pure N2 four times as much as the case of reversible heat exchange.

摘要： PURPOSE:To reduce solidification onto a cryogenic panel and prevent peeling of solidified matter by constructing such that a gas component having high saturation temperature is brought into contact with a low temperature adsorbent prior to solidification then adsorbed and caught. CONSTITUTION:A cryogenic pump comprises a cryogenic buffle 6 and cryogenic (respectively 70-100K and 10-20K, for example) outside and inside panels 1, 2 coupled to the cold stages 4, 5 at the first and second stages of a helium refrigerating machine 3. Here, a panel 7 adhered with adsorbent in the downstream of the buffle 6 is coupled to the outside cryogenic panel 1. Active carbon, molecular sieve, etc. is employed as said adsorbent in accordance with the gas to be treated. The panel 7 is constructed by supporting a multiple cylinder 15 on a supporting cross frame 14, and then the gas having high boiling point and solidified onto the outer face of the inside panel 2 is absorbed and removed by means of the adsorbent.
