Hello everyone my name is Scott Barnhard and I’d like to welcome you to what will be a series of presentations concerning topics of interest in the Pulp and Paper field. I fondly refer to this series as….. “What you always wanted to know about chemical applications but were afraid to ask”In the last few years there has been significant growth in the use of Pulping Aids or chemicals other than AQ. Like any chemical application there have been successes and failures. Some of the failures have been due to one or all of the following: unrealistic expectations, below threshold feedrates, the improper application of the pulping aid into the process and or the use of inferior technology.Because there seems to be much interest about this application I thought it would be a good first topic to explore.So we will attempt to review the good, the bad and the ugly about Pulping Aids. Over the next few weeks I’ll make available other presentations covering some additional items to consider regarding the use of pulping aids. And if you do decide to explore this application I am hopeful that you will be better prepared to have a meaningful discussion with the chemical supplier of your choice before making any final decisions. For the chemical suppliers, I believe this is a good opportunity to better understand this relatively new application, develop new chemistries and application technology that will make our industry more productive than ever. There is one small caveat and that is the concept is actually fairly old but recent high energy, chemical and fiber cost have rejuvenated an old idea.Before we proceed I’d like to disclose that I have worked for suppliers that sell pulping aids and consulted for mills that were considering using pulping aids. I have also manufactured these products. However, at this time my company Fiber-Wise Consulting LLC does not sell or manufacture these products. And finally I am not recommending this application nor discouraging it’s use, but rather attempting to present thoughts, ideas and concepts that might help you make the right decision for your business.
A lot of different ideas….every company has their own thoughts on how pulping aids work and some of them might actually be correct.But we do know in most cases there are 1-3 mechanisms at work: 1. wetting the fiber source more quickly and efficiently with the available alkalinity 2. moving and dispersing the lignin out of the fiber source 3. limited solvency in some of the available technologies to more effectively and thoroughly complete the cooking process. We also know that some pulping aids go with the liquor and some follow the fiber….. This is a very important issue especially for integrated paper mills because of potential impact to the papermaking system. But this topic will be covered in future presentations.
So let’s see what this program can do……………read read read read on one breath!!!!The real question is “Is there anything this program can’t do?” I can hear the thoughts of many of your right now…it’s ok you’re not going to hurt my feelings…remember I am not trying to sell this application but rather discuss it. Yup it sure sounds like a modern day snake oil.We all know that all of the features listed here cannot be simultaneously achieved because that’s not how the pulping process works and one thing I have forgotten to mention but you already know what I am about to say….. There is a cost associated to these chemical programs so that a payback must be achieved. I will be the first to admit that I am not a pulping expert but I do have some experience in this area. I know that for a pulping aid program to be successful you must choose the correct combination of features, have the right chemicals, apply and control the chemical program properly to the system.But now for a little humor and maybe what I call an overlooked opportunity…. Most of the chemical companies selling pulping aids today overlook the positive impact to the paper side of the mill.So at the risk of sounding like a promoter on television…. “if you consider this application right now we’ll throw in the following features for your papermill”
When you combine the many features and benefits of the Pulping Aid Application it just seems like the increased productivity and bottom line improvements are a “slam dunk”…… but not so quickly. As in all applications you have to find the right chemical product for your fiber source…The right application point because it does change for each facility….Find a supplier that is willing to work hard for you….And if we are talking about an integrated mill then there must be a good working relationship between the pulpmill and papermill. The production manager and mill manager need to look at the total savings from both production areas and proportion out the cost of the program to each. I have seen many a pulp mill manager say hey I am not going to bare the full burden of this program cost but only receive 50-75% of the savings….I can’t really blame that manager for feeling that way. So this is just an accounting issue that can be adjusted for if the application is successful.Finally I believe you should still consider equipment solutions to see if any of those could be more cost effective. But in these times when capital money is tight, a chemical solution might be a shorter path to lowering costs and possibly improving bottom line profitability. And in the long run could justify capital expenditure.
I hope this first presentation wasn’t too long but maybe peaked your curiosity enough to look for my next installment. If you liked this discussion please let others who might have an interest know about it. And remember if you have any specific questions you would like to discuss please send me and email or just give me a call.
Finally on a personal note I would like to mention the passing of one of my friends who was bigger than life and very devoted to this industry, Jim Gilpatrick. During his career, Jim worked in Tissue Production, sold paper machines and then as I jokingly told him…. he crossed over to the darkside by selling chemicals. Jim was the owner of a chemical company based out of Hong Kong. And for those of us who were fortunate enough to be witness…Jim could sing Karoke with the best of them….I will miss you Jim….may you rest in peace.
