Automatic on-line chemistry monitoring system.

摘要

A system for automatically sampling, and analyzing samples of water supplied from various points in a power plant steam cycle system. A plurality of one-line monitors and calibration units provide continuous on-line monitoring of each, and an ion chromatograph unit semi-continuously monitors of a selected one of the influent fluid samples. Each calibration unit provides a conditioned influent fluid sample stream having predetermined chemical characteristics; the on-line monitors are calibrated using the corresponding conditioned influent fluid sample stream and the ion chromatograph unit is calibrated using the selected conditioned influent fluid sample stream. A control unit uses signals in a feedback loop and detects, analyzes and corrects steam cycle water chemistry.
