Summary: | PROBLEM TO BE SOLVED: To provide a gas deacidification method and reduction of an amount of the energy required to regenerate an absorbent solution abundantly containing acid compounds. SOLUTION: A gaseous eluent flowing-in through a line 1 is brought into contact with a liquid absorbent solution flowing-in through a line 9 in an absorbent zone ZA. The gaseous eluent in which the acid compounds are extremely reduced is exhausted through a line 2. The absorbent solution abundantly containing the acid compounds is discharged through a line 3. The absorbent solution once abundantly contains the acid compounds includes two phases: a first phase poor in the acid compounds and a second phase rich in the acid compounds. These two phases are separated in a ZS zone. The first zone is circulated to the absorbent zone ZA through a line 5 and the line 9. The second zone is supplied to a regenerating zone ZR through a line 4. The acid compounds are separated from the absorbent solution in the zone ZR. The acid compounds are discharged through a line 7. The regenerated absorbent solution is circulated again to the zone ZA through a line 6 and the line 9. COPYRIGHT: (C)2006,JPO&NCIPI |
