ON-LINE OPTIMIZATION AND CONTROL OF AMMONIA REMOVAL IN DISTILLATION PROCESSES

摘要

An embodiment provides a method for measuring ammonia in waste water near a distillation column, including: obtaining an aqueous sample comprising waste water from a distillation column; measuring, using a nitrogen measurement device that performs oxidation of components of the aqueous sample, an amount of nitrogen in the obtained aqueous sample to provide real-time nitrogen measurement; identifying an amount of ammonia in the aqueous sample, wherein the identifying comprises correlating the measured amount of nitrogen to an amount of ammonia; and adjusting, based upon the identified amount of ammonia, a level of alkali injected into the distillation column and an amount of steam applied at the distillation column. Other embodiments are described and claimed.
