专利汇可以提供Method for the production of high-purity, high-pressure carbon dioxide from a mixture of low-pressure mixed acidic gas专利检索，专利查询，专利分析的服务。并且A process is disclosed for producing high-purity, high-pressure carbon dioxide from a concentrated low-pressure mixture of acid gases including one or more sulfur-containing gaseous compounds, and carbon dioxide as the major gas in the mixture with the highest vapor pressure, the mixture containing less than 1 percent of nonacid gases. The process including the steps of: compressing the mixture of acid gases, cooling the mixture of acid gases to liquefy the mixture of acid gases, fractionating the mixture of liquefied acid gases into a high-purity carbon dioxide liquid overhead of about 99.95 percent and a liquid bottom of condensed sulfur compounds, and vaporizing the carbon dioxide liquid overhead in heat exchange relationship with the mixture of acid gases during the cooling thereof.，下面是Method for the production of high-purity, high-pressure carbon dioxide from a mixture of low-pressure mixed acidic gas专利的具体信息内容。

权利要求

2. The process recited in claim 1 including the step of further cooling said mixture in a second heat exchange relationship with a refrigeration means.

3. The process recited in claim 1 and including the step of reducing the sulfur-containing gas content in said vaporized carbon dioxide overhead from about 0.05 to about 0.01 percent by passing said vaporized carbon dioxide overhead through an iron oxide system.

4. The process recited in claim 3 and including the step of further reducing the sulfur-containing gas content in said vaporized carbon dioxide overhead from about 0.01 to about 0.002 percent by passing said vaporized carbon dioxide overhead through a molecular sieve system.

5. The process recited in claim 1 wherein said mixture of acid gases is compressed to a pressure in the range of about 300 to 500 p.s.i.a. at a temperature of about 40* to 200* F.

6. The process recited in claim 1 wherein said mixture of acid gases is compressed to a pressure in the range of about 325 to 350 p.s.i.a. at a temperature of about 40* to 110* F.

7. The process recited in claim 1 and including the step of drying said mixture of compressed acid gases prior to cooling said mixture of acid gases to prevent the formation of hydrates in said mixture of acid gases.

8. The process recited in claim 1 wherein said mixture of compressed acid gases is cooled by said liquid bottoms of said sulfur-containing gas to a temperature of about 50* F. at a pressure of about 315 to 340 p.s.i.a.

9. The process recited in claim 8 wherein said mixture of compressed acid gases is further cooled in heat exchange relationship with said carbon dioxide liquid overhead during vaporization of said carbon dioxide liquid overhead to a temperature of about 40* F. at a pressure of about 310 to 335 p.s.i.a.

10. The process recited in claim 9 wherein said mixture of compressed acid gases is further cooled in heat exchange relationship with said refrigerating means to a temperature of about 35* to 40* F. at a pressure of about 305 to 330 p.s.i.a.

11. The process recited in claim 1 wherein said mixture of compressed acid gases is cooled to a temperature of about 35* to 40* F. at a pressure of about 305 to 330 p.s.i.a.

12. The process recited in claim 1 wherein said sulfur gas containing liquid bottoms is heated and reintroduced to the fractionating of said mixture of acid gases.

13. The process recited in claim 1 wherein said carbon dioxide liquid overhead is refluxed to the refractionating of said mixture of acid gases.
