Abstract
Monitoring and controlling the reactivation of an alkanolamine solution containing heat-stable salts of such alkanolamine with stronger acid anions and weaker acid anions by contacting the alkanolamine solution (a) with a strong base anion exchange resin which has a high affinity for stronger acid anions (b) contacting the effluent alkanolamine solution from the strong base anion exchange resin with a second strong base anion exchange resin which has an affinity for weaker acid anions (c) measuring and recording the electrical conductance of the effluent solution from the first mentioned anion exchange resin (d) removing the first mentioned anion exchange resin from service when the conductance of the effluent alkanolamine solution from said resin indicates breakthrough of stronger acid anions in said effluent, (e) measuring and recording the electrical conductance of the effluent alkanolamine solution from the second mentioned anion exchange resin (f) removing the second mentioned anion exchange resin from service when the conductance of the effluent alkanolamine solution from said resin indicates break through of weaker acid anions in said effluent and (g) regenerating the strong…
