Design of Heat Exchange Network
Question
A process has four streams with equal mass flow rates and the characteristics given below. Devise a heat-exchange network to minimize the amount of the utility streams, water and steam, that must be used to accomplish the desired change in energy state of the four streams. You can use as many heat exchangers as you need to. Consider using cross-exchangers in your design.
Process Stream Inlet Temp.oC Desired Outlet Temp. oC
A – ethanol 60 160
B – 80% ethanol, 20% isopropanol 160 93
C – 20% ethanol, 80% isopropanol 116 220
D – propanol 250 138
Available utilities:
Cooling water at 25 oC.
Saturated steam at 150 psg
Summary

WHAT OUR STUDENTS SAY
I was not aware what sort of things actually needed to be added in the research proposal and my college advisor was also not that clear. However, to my surprise the New Zealand based research proposal writer of HwA added so many important things like a brief review of literature, data collection method etc in my research proposal that not only I got an A+ grade but my paper is now showcased as a model paper in my college. Made me super proud.

My main concern was the relevant local Wellington research and reference work that was required for the final Statistics Assignment for my post graduate program at the Victoria University of Wellington. My professor was very particular about his requirement of relevant local data and samples from Wellington. With the stats assignment expert at TheReliableTutor I did not have to worry about that since the expert provided the most excellent and relevant local data and references helping me to top the class.

My dream of becoming a software engineer was made real by the programming assignment help experts of HwA. I completed by B. Tech last year from an university in Auckland and the experts knew exactly on how to proceed with all the programming solutions.
Sean Taylor Student
The coding is without flaw and only minor changes may have to be made now and then in the Programming assignment help that I have been receiving from TheReliableTutor. The packages are very affordable, that coupled with the highly qualified and professional online programming assignment experts residing in Singapore has definitely helped me get the top grades and hassle free services.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
