it's your board. i say go for it.

Posted by KublaKhan This is still very funny.

It feels so good to be so appreciated.

we've covered cars, sex, mountain dew, music and food already... what's left?

by the way, I am pissed off that Spring seems to have called in sick this season.

Pulp squish.

people are tired of hearing about where i work.

I'm always up for a bit of paper industry action.

Some people are tired blah blah blah...I'm not one of them.

So tell me in graphic and explicit detail: pulp squish and how it's made.

i swiped a bunch of pictures from work the other night from a disconnected network drive, but they are ENORMOUS and i don't have photoshop on this computer yet...

making pulp is retardly simple.
you take woodchips, separate them between hardwood and softwood. into the steaming vessel to make them gooey. into the top separator and into the digestor, all 187feet of it. dose the chips with white liquor and steam... takes anywhere from two to six hours to make the trip down the digester depending on RPM. from the digester, into the diffuser, from the diffuser into the blow tanks, from the blow tanks into the brown stock washers, into the screen room, into the deckers into the brownstock hardwood Hi-Do or brownstock softwood Hi-D silo or right to the Lo-D tank... into the Sunds Mixer (where its dosed with Chlorine Dioxide), down 10 line into 10 tower and then into the bleach plant.


asleep yet?

No. I find it fascinating. Tell me the story again.

I really did find it interesting.

So there, KK.

What about wax paper? And cardboard?! Don't forget cardboard? That's a papery product in a way!

where i work makes fine freesheet uncoated paper. Basically the stuff that corporations print presentations on. we get fucking $$$ for this stuff.

the bleach plant, in of itself, is a monster of complexity and there are chemicals in it that will just plain fuck you up.
when the pulp, which is still brown at this point, goes into ten tower, it's already been dosed by the Cl02 and being in the tower it gives what called retention time. That means the chemicals have a chance to act on the material. From ten tower, the material goes into what's called a Washer. 15 Washer to be precise. A washer works like this:
One side is the vat side, this is where the material is more or less liquid. The tower stock valve and vat dilution pump supply the dilution to the vat. It overflows into the belly of the washer. In the center of the washer is a huge drum about 15 feet in diameter. Its covered by a fine mesh wire. Under the wire are passages that lead towards the center-front hub of the washer, called a trunion. The trunion is more or less a drop leg to the seal pit. The seal pit are chambers in the basement between the bleach and brown sides. From there, the dilution gets pumped out again... the flow pattern is more complex than this, but i'll keep it simple for now.
So the drum rotates on the trunion bearings and as it spins, it picks up the dilution out of the belly. This pulls a mat up on to the wire. Ideally, the mat is about 2" think. Anymore thicker and it can plug your repulper or thick stock pump in the basement. If the mat is thinner, you aren't washing correctly. At this point the mat is being carried over by the wire and a doctor blade with water jets pushes it off the wire and into the repulper, which looks like a big auger from hell... the repulper auger chews it up and carries to the downdrop at the back of the repulper chamber. From here, the pulp falls two stories into #20 thick stock pump in the basement. 20 TSP pushes the pulp through what's called an EO mixer. The mixer mixes caustic in with liquid oxygen. This is more for pH control (everything is a pH game with these bleaching stages).

The bleaching/extraction stages are pretty straight forward. 10 Tower/15 Washer are Chlorine dioxide or bleaching stages. 20 Tower/25 Washer is extraction or washing stage. This is where made down caustic is added to control pH. 30 Tower/35 Washer are again bleaching stages. This where the pulp gets zapped with Chlorine dioxide again. Also, there is a small amount of sulfuric acid added at this stage, again, to modify pH. From there, the pulp hits 40 Tower/45 Washer for more extraction washing and then into 50 Mixer/50 Tower and 55 Washer. This is the last bleaching stage. By this point, the pulp is bright white and ready to head for what we call the High Density (Hi-D) Silos... This where a small amount of Hydrogen Peroxide is added for final pH tweaking and another additive that is super secret. We don't even know what it is. The company just refers to it as "OBA" for Optical Brightener Additive. So at this point the finished raw pulp hits the Hi-D thick stock pump in the basement where it slings it into one of the four silos at our disposal. We have two for hardwood (#7 and #10), one for softwood (#9) and our species swing tank (#8). At our end, we have no control of these silos. Paper machines control room controls what silo they draw out of.

I left out the retention tubes and the workings of the chemical mixers and steam mixers on the mixing floor as well as the chemical reactors that produce the chlorine dioxide we need to bleach with.

Now, i know you're asleep.

Posted by Samurai Now, i know you're asleep.

No. I read every word and I find it all very interesting.

KK, you're my post bitch!
