    何謂吸附法製純氬？

    氬餾分從上塔抽出後，進入粗氬塔用精餾法進行氧、氬分離。一般粗氬塔頂引出的粗氬組分為：氬大於98%、氮小於0.5%、氧小於1.5%。將純度大於98%的粗氬導入分子篩吸附器。每組吸附器設置2台，一台吸附器內裝5A分子篩，吸附粗氬氣中的氮；另一台吸附器內裝4A分子篩，吸附粗氬氣中的氧。

    After the argon fraction is extracted from the upper tower, it enters the crude argon tower for oxygen and argon separation using distillation method. Generally, the components of coarse argon extracted from the top of the coarse argon tower are: argon greater than 98%, nitrogen less than 0.5%, and oxygen less than 1.5%. Introduce crude argon with a purity greater than 98% into the molecular sieve adsorber. Two adsorbers are set for each group, with one adsorber containing 5A molecular sieve to adsorb nitrogen from coarse argon gas; Another adsorber is equipped with 4A molecular sieve to adsorb oxygen from crude argon gas.
    為了吸附劑的解吸，吸附器需要設置兩組，切換使用。吸附器在90K溫度條件下工作，粗氬氣入5A分子篩吸附器除氮，然後進入4A分子篩吸附器除氧，其流程見圖18。從一組分子篩吸附器出來的氣體含氬純度可達到99.99%，即為純氬。

    In order to desorb the adsorbent, two sets of adsorbers need to be set up and switched for use. The adsorber operates at a temperature of 90K. The coarse argon gas first enters the 5A molecular sieve adsorber for nitrogen removal, and then enters the 4A molecular sieve adsorber for oxygen removal. The process is shown in Figure 18. The gas from a group of molecular sieve adsorbers can have an argon purity of 99.99%, which is pure argon.
    吸附法製氬的優點在於，工藝流程簡單、操作方便、成本低。但是，氬的純度隻能達到99.99%。由於受分子篩選擇吸附能力的限製，無法獲得純度為99.999%。A的高純氬氣。另一個缺點是，吸附器的工作溫度為90K，再生溫度為423K，吸附結構設計較為困難。
    The advantages of adsorption method for argon are simple process flow, convenient operation, and low cost. However, the purity of argon can only reach 99.99%. Due to the limitation of the selective adsorption capacity of molecular sieves, a purity of 99.999% cannot be obtained. A's high-purity argon gas. Another disadvantage is that the working temperature of the adsorber is 90K, and the regeneration temperature is 423K, making the design of the adsorption structure more difficult.
    吸附器工作時，床層必須冷卻，往往需采用夾套或管內通液氧冷卻。若想達到均一的冷卻溫度，對於大型製氬設備所需直徑較大的吸附器來說，就十分困難。因為有以上兩個缺點，限製了吸附法製純氬的應用。目前，國內吸附法製氬能力不超過10m3/h，隻在150m3/h空分設備配套的製氬設備上采用，在大型製氬設備上尚無應用。
    When the adsorber is working, the bed layer must be cooled, often using a jacket or liquid oxygen cooling inside the tube. It is very difficult to achieve a uniform cooling temperature for larger diameter adsorbers required for large-scale argon production equipment. Due to the above two drawbacks, the application of adsorption method for pure argon is limited. At present, the adsorption method for argon in China has a capacity of no more than 10m3/h and is only used on argon production equipment matched with 150m3/h air separation equipment. It has not yet been applied to large-scale argon production equipment.
