For those of you challenged with the vagaries of pH control, I wanted to make sure you had seen the news of an upcoming pH Control web seminar, arranged by ISA, featuring ModelingAndControl.com’s Greg McMillan. The web seminar covers the root causes of poor performance in pH control systems.
In a recent post, Greg describes how he plans to share his experiences:
I spent a lot of time on pH startups. I found most of the key design concepts needed for success where not discussed anywhere, For example, the normal dip tube design for reagent injection is disastrous and the mixing and valve resolution requirements are exceptional. I discovered how I could reduce the number of stages of neutralization, offer inexpensive alternatives to the classical neutralization vessel, and decide when signal characterization could help or hurt your control objectives.
Unlike his recently released free eBook, this May 16 web seminar (2:00pm – 3:30pm Eastern U.S. Time) does have a cost. It’s $195 (USD) for ISA members and $225 (USD) for non-members. If you’re not the lone person in your organization who struggles with pH control, Greg suggests:
The seminar is much more cost effective if the registrant connects in a conference room with a computer projector.
If you can’t make this event, Greg has also published a book on this topic, Advanced pH Measurement and Control, 3rd Edition.
