17 Aug 16: 7th Annual LGMI Conference at NCSU in October--abstracts continue

As we have announced, the Seventh Annual Light Green Machine Institute Conference will be held 16 - 18 October in Raleigh, North Carolina, in cooperation with North Carolina State University.

We'll start with a reception on Sunday evening, 16 Oct, and wrap with a tour of the university's Paper Science and Engineering Department.

We have jam-packed program in store for you. You can see the program -- and sign up -- here.

New this year, we will have a student competition and a table top exhibit area.

From now until the conference, we'll highlight some of the talks to be given.

Dr. Peter Hart of WestRock, who has been a long standing contributing presenter, will offer a second paper this year (we covered his first one last week):

Title: Application of Carbon Dioxide to Reduce Water-Side Scale in Heat Exchangers 
 
Abstract: The WestRock mill in Evadale, TX, has been experiencing significant lime-scale problems with its peroxide bleaching stage heat exchanger. Typically, the exchanger has had to be removed from service after 20 to 30 days of operation and cleaned (hydroblasted) to remove lime scale. Carbon dioxide was applied to the water side of the heat exchanger in an effort to buffer and to lower the water pH. By lowering the pH of the mill water from approximately 8.5 to less than 7.5, the solubility of calcium carbonate in the water was substantially increased, effectively eliminating lime scale formation in the heat exchanger.
