Dear respected admin and others,

 

I am a undergraduate student from Malaysia, we are in the middle of completing of our Bachelor in Chemical Engineering in which we are required to finish up the Design Project course.

 

Our objective is to proposed the chemical plant to produce 1,4-butanediol. Thus we want to know the detail about the process of producing 1,4-butanediol. As far as what we have done, we already did patent search and acquiring so much information. However we are stuck because too much information and those incomplete information lead us to a dead end.

 

We are looking for the full chemical reaction that occur, the kinetic data, the process flow diagram, the process and instrumentation design (P&ID) as well as the operating of the every equipment for producing 1,4-butanediol. We not hoping you guys to give direct answer, however if you could guide us on where to find the required information that should be fine already.

 

Last but not least, i want to ask that if i am proposing for 10ktpa of butanediol for internal supply it should be fine or not?

 

This is solely for the academic purpose thus, the information given hereafter will not be duplicated or copy into another form but will be cited into our research report. thus we are trying to get the most valid information as much as possible .

 

Sory for the inconvenient. Your help is much appreciated.

 

Thank You.

 

Regard.

Apit:

 

If you have done extensive research (as you should), then you already know that you can produce 1,4-Butanediol by:

• Reppe Chemistry, using acetylene and formaldehyde as your raw materials;
• Using propylene oxide as your raw material;
• Using maleic anhydride in the Davy Process;
• Using metabolic processes;
• Other processes.

Knowing the above, why don’t you specify which process you have selected to study and design?  We can’t read your mind.

 

You say you want to receive:

• the full chemical reaction that occur;
• the kinetic data;
• the process flow diagram;
• the process and instrumentation design (P&ID);
• the operating instructions for the equipment.

If you receive the information (which is highly unlikely) what are you guys going to design?  You are asking for the answer for the project you are required to design.  If you want “guidance” on where to find the information, look in Google – but you already said you did your research.

 

The answer to your situation is to use your ingenuity to resolve your project.  That is what your instructors want to find out because that is the measure of any engineer.  In order to qualify as a graduate engineer you have to prove you have and can use your ingenuity.

Dear Montemayor,

 

Thanks for your fast reply, yes i am already aware that 1,4-butanediol can be produce basically from 6 popular method as stated above. I am sorry because its my fault not stating that we are stick to use davy process which is the maleic anhydride act as raw material which goes esterification reaction react with methanol.

 

I was read your reply on some post before this that u are well with THF production from furfuran. thats great as thf is our side product from GBL and BDO based on patent search.

 

My problem is that i want to start the hysys simulation however, we do not have a valid pfd as a reference. if we draw or making our own pfd, how we want to know the operating condition for those equipment. Because before this we were asked to follow the patent as guidance to get the conversion and so on so forth.

 

Sorry for your inconvenient as I am not a very excellent students in my universities as well as English is not the mother language thus i am sorry for bad grammar.

Hi,

 

Hope this helps , not sure

Dear Breizh,

 

Thank for your effort. However i already read that book and go through many others handbook such as ullman, kirk othmer and others.

 

As i said earlier, those information given is not detail enough. My problem is i want to find out the reference that say A+B-->C at certain temperature and pressure yield this much product. that is what i want to find out and also i want to find out the effect of the catalyst toward the reaction, its mean the kinetic data that justify by using this catalyst it will speed up the reaction this much.

 

That book only gave pfd for Davy process however, the problem arise when no GBL produced is stated in that book.

 

Once again thank for your help and sorry for any inconvenient

 

Regard.
