There are different levels of refrigeration with various types of efficiencies.
Would like to know the various efficiency range (preferably VDMA 24247) for Both small systems (Home refrigerators) and large scale industrial systems (Industrial refrigerators)
Water systems i.e. 40 deg C to -4Deg...
As a student, we would love to have the opportunity to talk with Engineers, in case you are interested.
May I request if we can arrange a meeting of like-minded professionals to meet or have a chance for the students to talk to them?
Please comment in case you are interested to talk. I...
From the following table is it possible to calculate the pre-exponential factor? Any relevant text software we can find preexponential factors? Wiil RMG software able to do it?
The reference of the paper is

RMG software...
The reaction is highly exothermic.
The reactor is designed in such a way that heat can be removed from the catalyst. Otherwise, Ignition can happen.
So heat removal through jacket is major work in reactor design.
Now is there any software that can help me design the jacket surfaces are...
The reference I am following
https://www.ou.edu/c... of Freedom.pdf
So according to the reference we have two degrees of freedom
So if is specify the number of stages and feed locations are the systems fully defined?
So in my case, I have strict feed concertation A & B
Distillate...
Hi, I am a 2nd-year grad student. This would probably be my first in-person AIChE. (if it happens).
I am super excited but also a little confused how should I prepare?
The reason for my confusion is, I have a wide range of experience in my tiny career.
BSc Chemical Engineering (Asia)
Worked as...
I am using Aspen plus to simulate a process where we have to separate the product and undesired product in Separation 1 column and Separation 2 column equipment respectively.
Both of the separation columns use water, so they have some amount in their respective outlet stream based on the...
Dear ChemEs
I know that in reversible reaction the reaction will get forward or backsword depending on le chatelier principle.
But if we have multiple reactions happening on the surface of the catalysts, how the reactions get affected if we have for example higher pressure or higher heat...

Chemical Engineering has been an excellent versatile experience for me.
Would like to know if any chemical engineer is working as Energy Analyst.
What is that job prospects and what are the challenges, and maybe what are the day-to-day activity?
Currently, I am a graduate student with...
One of the most in efficient and hard to control process.
Any Altruist in Ethylene Oxide Plant?
What are generally per pass conversions nowadays?
What about fractions of oxygen conversions in the reactors?
Would appreciate any info.
Thanks
I know selectivity is = No of mole of desired product formed/ No of mole of reactant took part in the reaction (reactant Basis)
Ethylene Oxide example
Considering only the first two reactions (No further oxidation of EO)
Assume 153 Kmol/hr of EO forms
So if I have 90%...
My notion was that we should use counter current in the jacket because of efficiency but my friend said
"The co-current system is often used in industry for example, protection of acid corrosion economizer, temperature cross-over, etc."
In our case the case of this PBR, the inlet...
I am a little perplexed seeing how my column is getting/not getting converged.
I am working with CO2 separation by K2CO3. Aspentech has one reference example file. But when I try to increase BOTH (the lean solvent flowrates and K2CO3 concentration) to serve my purpose (different CO2 removal...
Respected forum Members,
I am trying to simulate a separation column in ChemCad,
I have taken the exact specs given in the literature and used in the ChemCad simulations. But the simulation does not provide any results in the outlet stream (all zeros) or any warning.
ChemCad file...
I know we can override the default global options in each unit operation in aspen plus.
But I have to use regression in two of the property package. So as far as I know we can do regression in only principal property package. But I need in total three property package and and two regressed...
I was going through some literature, stumbled upon one great diagram.

Would be great if anyone has come across some more of this, maybe some reference material...
The major goals of designing pilot plants are.
1. Prove the specified technology can perform with satisfaction at the capacity that has been built.
2. Prove the economics work if the plant is scaled above the pilot plant scale.
What things should we consider while designing such a...
