The extreme capability of the pH measurement and the broad spectrum of applications and process conditions create exceptional requirements for electrode design, mixing uniformity, control valve precision, deadtime minimization, nonlinearity compensation, and control strategies. pH loops are often the most challenging loops in the plant. Slight deficiencies in the mechanical, piping, process, measurement, and control …

There are numerous examples where equipment design by not taking into consideration dynamics caused poor control. A good equipment design should reflect an understanding of how dynamics affect control loops and the efficiency and capacity of the production unit. Most advanced control opportunities arise from equipment deficiencies that become particularly evident as plants are pushed …
