I've been watching 10+ videos so far and cannot understand why I still don't know how to make crystal meth yet? xD One subtle mistake, in the video you said "filter cake" refers to the solid portion of the crystallizer product, when it is really referring to the total mass product from the crystallizer.
Chemical Engineering Guy I have to politely disagree. Even if in real life, filter cake refers to the solids portion..... In this problem, it is worded in an unclear way. Somewhere along the way you said that (crystals=solids) and now you are saying that the (filter cake=solids) as well. By transitive property then, (crystals=filter cake) but it says that "the crystals account for 95% of the total mass of the filter cake," which means they cannot be equal. Do you see what I'm saying man? Or maybe I'm just crazy... :D And just to totally clarify without a doubt (correct me here if I'm wrong), the 95% refers to the solid which is 100% Potassium Chromate (?) and the 5% refers to the liquid portion to be recycled at 36.4% Potassium Chromate.
I just saw this video now. Can you please explain to me what is Pd and how is it different with Ps? I also got confused in the OMB part, since the OMB said that F=Qw + P, P should be equal to Pc + Ps. How come the OMB only added the Ps instead of P? Thanks in advance. :)
Thank you so much for all the help with your videos, those are really helpful. However, it would be much much better if they were more clear. Here, for example, the thing about Pd and Ps, I don't see the difference, is there any? for me is really confusing, additionally, there are also constant mistakes with calculations. PLEASE, I appreciate all your help, but this can be counterproductive if there are these kinds of mistakes. Thank you again!
can you or anyone tells me how the recycle stream works in real industry process, like inside the unit how it is being separated and leave with special stream and products leave with another without combining at all? Thanks
Recycling in real life is nothing but a pipe with the stream being recycled or transported back to the system. Typically, you will either treat it (cooling/heating, pressure adjustment, etc)
@@ChemicalEngineeringGuy so what is really going on inside a process unit, say a reactor, is that there will be different pipes stream inside the unit that let materials in depending on pressure and temperature differences or phase change? thank you
Agradezco el esfuerzo de explicar este tipo de problemas, pero tiene demasiados errores. Para empezar la notación de Ps, Pd y Pc confunde al grado de que tuve que tardé una hora descifrando que significaba cada una, ya que pones el mismo símbolo para distintas variables. Segundo, al sacar la relacion entre Pc Y Pd pusiste 0.563 cuando en realidad es 0.05263. Ese es un error de dedo y no de cifras significativas. Posteriormente al obtener el flujo Pd (15:34) obtienes como resultado 77.5 . Al corregir los datos desde el principio en realidad se debería obtener 77.367, pero utilizando la relación que sacaste (0.0563) se obtiene 82.761. Estos errores son importantes y pueden llevar a la confusión a tus suscriptores, como fue mi caso. Te pido mejor manejo de las cifras significativas y mayor claridad con la notación. Gracias

Chief Mongol Filter Cake is all the solids. The total mass product would be the filter cake (solids) + liquids being separated

Where did the years go.. I am sure now that you had graduated🌺
Hi, for the equation:
1500 = Pc * (0.3636*0.0563 Pc),
can you please clarify again because I found out the answer should be 273.724 kg/h
Hi please I don't know what Pd, PS and PC stand for please. A hope for a quick reply. Thanx
Pc = Product - Crystals ; Ps = Product solution
Thank you sir am greatfull .. thanks very sir. But what dose PD stands for. And are they all in kg/hr..... thank.
@@kayoderilwan9864 Yes, in my opinion all the mass flow rates are in Kg/h

Thank you again!
Noted! I will work on that
great help thanks :) i tried to answer the question before looking at yours and i have a bit discrepancy in my answer but yeah it still close
discrepancies are always common in engineering :) make no worries, the idea is that you get a "similar" value
Thank u sooo much sir for helping with ur videos 🤗🤗🤗🤗🤗...
It's my pleasure

Hey there. I don't understand why Pd = 0.05( Ps + Pd). could you explain it to me Sir? Thank you :)
I don't see Pd labelled anywhere in the system
+Fred Loemba it comes from NOTE 1: 95% are solids, therefore 5% are liquids (which is actually a solution)
Thank you sir I get it now
no worries! keep the good work!

I will consider this for future work! Thanks for the feedback!
oye me quisieras decir que significa el Pd porfa yo todavía no lo entiendo
En 15:47 cambias el 77.5 por un 72, neta ¿Qué pedo?
I will consider this for future work! Thanks for the feedback!
r u fan of braking bad 😃😃😃
you're goddamn right
best lecture thank you
Thanks!
