<p><P>PROBLEM TO BE SOLVED: To reduce additional steam consumption for reclaimer operation in a CO<SB POS="POST">2</SB>chemical absorption system. <P>SOLUTION: The CO<SB POS="POST">2</SB>chemical absorption system has a steam system reclaimer 70 in which a heat-stable salt (HSS) accummulated in a CO<SB POS="POST">2</SB>absorption liquid is removed by a distillation method and then produced vapor of the CO<SB POS="POST">2</SB>absorption liquid is supplied to a regeneration tower 40. A method for controlling the CO<SB POS="POST">2</SB>chemical absorption system is characterized in that HSS concentration in the CO<SB POS="POST">2</SB>absorption liquid extracted from the regeneration tower 40 is measured and when the concentration exceeds a prescribed value, steam supply from a steam supply line 73 to the reclaimer 70 is started and in keeping with the start, steam supply to a reboiler 60 is reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
