Title:
MIXED GAS SEPARATION APPARATUS AND METHOD FOR SEPARATING MIXED GAS
Document Type and Number:
WIPO Patent Application WO/2023/087519
Kind Code:
A1
Abstract:
A mixed gas separation apparatus and a method for separating mixed gas. The mixed gas separation apparatus comprises: a buffer tank (10) comprising a first buffer tank inlet (101), a second buffer tank inlet (102), a third buffer tank inlet (103), and a buffer tank outlet (104); a compressor (20) comprising a compressor inlet (201) and a compressor outlet (202), the compressor (20) being configured to compress mixed gas; a pressure reducing valve (30) comprising a first pressure reducing valve interface (301) and a second pressure reducing valve interface (302); and a refrigerator (40) comprising a refrigerator inlet (401), a first refrigerator outlet (402), and a second refrigerator outlet (403), the refrigerator (40) being configured to lower the temperature of the mixed gas. In the mixed gas separation apparatus, the pressure reducing valve (30) is disposed between the compressor outlet (202) and the second buffer tank inlet (102), so as to ensure that the pressures of gas in the components at the rear end of the compressor (20) and pipelines do not exceed a threshold pressure, thereby preventing damage to the apparatus and improving the working safety of the apparatus.
