Talk:Kraft process

Jargon
I think the writing here is good, but I tagged it with "jargon" because terms are defined out-of-order. Particularly in the process section, "jargon" terms like "black liquor" are used before they are defined. I'm trained in chemistry and had a bit of trouble following these passages. I don't mean to offend; I just don't have the time nor energy to help edit this article right now. I think it would help a lot to either < use more standard terms for reagents wherever possible > or < create a table of reagents like black liquor at the head of the article > or < describe each term using general language before defining it >. Remember, lots of curious people like me visit this page without prior knowledge of the industry!

 * I cannot see that your claim that expressions are used before they are are explained hold. Black liquor is explained the first time it is mentioned. I only find that green liquor have a red link, but that might be fixed soon. The branch jargon is the standard terms. If noone else complains I will remove the jargon tag. Remember also that a lot of people read this without chemistry knowledge. --Langbein Rise (talk) 09:58, 22 February 2011 (UTC)

Expansion - Kraft paper
Since Kraft (paper) and Kraft paper redirect here (I made the second one without looking at the article thoroughly), the article should talk about them or a new article should be started about them. It may be more appropriate to start another article, since the Kraft process appears to produce more types of paper than just Kraft paper.

Green liquor and White liquor
I was wondering if someone knowledgable about the process could talk about green liquor and white liquor; specifically, what they are and how they fit in the process. Thanks. --Pesco 16:28, 16 May 2007 (UTC)

(Apologies to Pesco, but this seemed the best place for this note) It is worth noting that the Recovery Process section indicates that no one knows where the name "green liquor" comes from, yet the pop-up summary of the linked article on green liquor indicates right in the summary box that the green color is due to colloidal iron sulfide. That item probably needs to be harmonized. [User:PA28pilot] — Preceding unsigned comment added by 72.66.57.3 (talk) 04:51, 27 November 2020 (UTC)

Merge
I agree with the proposed merge of Black liquor page with the article on kraft process. Black liquor is a very limited topic by itself (at least for a non-specialized work like Wikipedia) and is covered completely in the kraft process article.Silverchemist 04:12, 12 September 2007 (UTC)


 * Release me from this problem. 2601:602:8701:649C:95A8:CB5D:D841:6D0D (talk) 18:37, 25 January 2024 (UTC)

Black liquor from the kraft pulpng process
I would= keep the article separate from kraft pulping, since black liquor refers to both bleached and unbleached kraft pulping, and is also one of the key water pollution issues remaining in this industry —Preceding unsigned comment added by NMcCubbin (talk • contribs) 02:09, 3 October 2007 (UTC)

Languages

But http://en.wikipedia.org/wiki/Kraft_process only have: Español Italiano Suomi 中文

I miss Svenska. —Preceding unsigned comment added by 217.213.69.190 (talk) 01:23, 14 April 2008 (UTC)

Delignification reactions
It will be important to carefully define the chemical reactions with models and real lignns. The current picture captures the idea that the SH- breaks up the C-O-C linkages, but episulfides seem like unlikely products.--Smokefoot (talk) 14:08, 19 December 2008 (UTC)


 * Episulfides and analogous epoxides are intermediates only. See E. Sjöström (1993). Wood Chemistry: Fundamentals and Applications. Academic Press (ref 2 in the article). They both undergo ring opening by various nucleophiles present in the reaction system. Silverchemist (talk) 14:52, 19 December 2008 (UTC)

Name?
So why is it called the "kraft process"? DS (talk) 14:20, 15 January 2010 (UTC)
 * The name of the process is coming from the German word “kraft,” meaning strong. Langbein Rise (talk) 09:06, 16 January 2010 (UTC)
 * Because it enables the creation of stronger fibers, or...? DS (talk) 14:01, 16 January 2010 (UTC)
 * Correct and is used in f.ex.: sack paper. Langbein Rise (talk) 12:59, 18 January 2010 (UTC)

Jargon?
As an educated but non-chemist I find this to be a well written article with a minimum of arcane technical jargon.

`me too. —Preceding unsigned comment added by 81.152.178.136 (talk) 23:48, 15 May 2011 (UTC)


 * There are certainly many technical terms, but that is the the reality of the process. The terms are either explained or Wiki-linked. I'm going to remove the jargon tag. Silverchemist (talk) 01:31, 16 May 2011 (UTC)
