Missing info in Appendices

[Marek Podyma]

Has anyone noticed there is no PFD or P&ID in our Appendices or are we submitting that as stand alone ( probably). mAlso Murtaza you must confirm that the pipe diameter comming from the buffer tank to the digester is 8 inch , If so i have chaged our P&ID to match but i have not changed the Doc. WHY ARE THERE TWO VERSIONS OF THE FINAL APPENDICES ? I warned you about conflicting copies.

[LEIcl_nn2006]

Yes, after my calculation. With a pipe diameter of 8in greatly reduce the amount of pump power required. I also change the pump diameter for Pasteurization to buffer tank to 8in.

Otherwise, I done formatting the final report. Just a word of caution, if you copy anything with a reference, remember to "keep source format". Otherwise, it will show invalid reference.

Mutaza, there is 2 reference in your section. because you use "keep text only" there is no reference for it. please fix them after marek done.

I just realized that the orientation of the plant on the geographic photo is wrong. The long and wide should flip. Whoever is currently editing please change that. Otherwise, I will change it when everybody is done.

The current logic "The contents of each tank are replaced every 1 hour and 30 minutes. This time includes 15 minutes to fill the tank, 1 hour for feed pasteurization, and 15 minutes to empty the tank. "

think about this. When the first tank just being filled and start pasteurized, the second tank will start filling imminently. And it takes only 15 min to fill. Then, after second tank finish filling, third tank will start filling. And the overall time is only 30 min. Then what do we do for that rest of 30 min where all the tank is filled and being pasteurized? The purified feed from pretreatment has nowhere to go.

So, feed in time must be the same as holding time. feed out time can vary as long as less than or equal to feed in time. If feed out time equal to feed in time, we can ensure constant flow to the buffer tank. If less, we have discontinuous flow to the buffer tank.

If you do not understand it. map it out yourself.

When first tank being hold for pasteurized, the second tank is being filled. It takes 1 hour to fill. Once second tank finish filling, the third tank is being fill, and the same time the first time has finish pasteurizing and is ready to empty. If filling time and emptying time are equal, the third tank filling and first emptying happen simultaneously.

I fixed it... We missed a lot. Our report is utter useless information. We have great ideas but none of it is well explained. Finally approaching page 20.....

Since we have some many extra heat, why dont we just do a thermophilic.

Since the selling digestate generate so little profit, why do we just separate it and dispose the liquid and solid.

Why not just generate steam with extra heat, then use the steam to generate electricity.

[LEIcl_nn2006]

In addition to that, all the question ask by Todd on the document.
