This post was last edited by adsl121 on 2009-12-29 20:00 The high H2S in lean solution may be caused by the following aspects: 1) Check the concentration of amine solution. 2) Clean the amine liquid filter regularly to prevent the amine liquid from deteriorating. 3) Control the temperature at the bottom of the tower to prevent the regeneration effect of the amine liquid. 4) Control the temperature of the amine liquid after cooling.
Replenish: First of all, we should clarify the real reason why the liquid is poor but not poor.: Is there a problem with the regeneration tower or is the lean liquid contaminated? The lean liquid is contaminated. Check whether the heat exchanger is leaking! Is there a problem with the regeneration tower that needs further inspection? Is it insufficient reflux? Tray tipped over? Reboiler efficiency failure? Float valve disengaged? and other reasons. Once it's clear, it'll be easier to handle, right?
Control the amount of absorption circulation and circulation stability.
