Freon-12 (R-12), at a flow rate of 12,000 kg/h, is to be heated from 250 to 300 K. Ethylene glycol (EG) is available at 370 K. A typical shell and tube heat exchanger will be used. The plant engineer recommends that the minimum temperature approach should be at least 15 K. She/he also recommends using 20 BWG carbon-steel tubing with a pressure drop not exceeding 5 psi (0.34 atm) for either the ...

PROBLEM DESCRIPTION we have a 50/50 wt% mixture of water and n-hexanol. We plan to separate this mixture into its constituents and ultimately end up with almost pure streams of water and alcohol. The total flow rate of “H2O C6OH” stream is 100 kg/h at 25∘C and 2 atm. The flow rate of “C8OH” stream is also 100 kg/h of pure octanol at 25∘C and 2 atm. The mixer exists under the same conditions of ...

A mixture containing 50.0 wt% acetone and 50.0 wt% water is to be separated into two streams: one enriched in acetone and the other in the water. The separation process consists of the extraction of acetone from water into methyl isobutyl ketone (MIBK), which preferentially dissolves acetone but is nearly immiscible with water. The overall goal of this problem is to separate the feed stream int...

Where can one get this Aspen software from ??
you have literally saved my life !!! an assignment was due like an hour before i saw this lol
What if we have inerts in the feed then how do you change the input stream
Hi Mulat, I'm trying to do something similar to what you show in the video. I need to create a component with these properties in Aspen: (Temperature, Mass heat capacity, Mass density, Viscosity, Thermal conductivity), it is for a heat exchange process, I would appreciate if you can make a video or give me some tips to achieve it. I share the table with the properties of the fluid. docs.google.com/spreadsheets/d/1WFKSifPtrpBWRNRrNtWKDkvL4nibB94Ct27ehVXfMlE/edit?usp=sharing

hi mulat can you please give me aspen plus download link
It is good
thanks
ma pleasure
Thank you for following my channel watching my videos....I will be uploading another video on distillation process...
was following you well, until the video cut abruptly Nice video, wondering what happened to the remainder of it
