Title:
ガス精製装置とガス精製方法
Document Type and Number:
Japanese Patent JP6562541
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device and method capable of easily and efficiently producing a high-accuracy refined gas while saving space.SOLUTION: A gas purification device 1 is equipped with first and second adsorption towers 6A and 6B, and adsorbs carbon dioxide from a raw material gas to separate and refine a primary refined gas. A finishing tower 7 is connected to the downstream duct 2a of the first and second adsorption towers 6A and 6B, and the inside of the finishing tower is filled only with an adsorbent adsorbing carbon dioxide. One tower of adsorption towers 6A and 6B adsorbs carbon dioxide; the other tower discharges carbon dioxide adsorbed on the adsorbent; and the adsorption and discharge of carbon dioxide are repeated by alternately switching. The primary refined gas after carbon dioxide adsorption by the towers 6A and 6B is supplied to the finishing tower 7, and carbon dioxide is further adsorbed to refine a secondary refined gas.SELECTED DRAWING: Figure 1
