Montemayor Thanks a lot for response. Prashant

Hi What is a typical value for lean amine loading in CO2 capture when MEA is used? I am trying to get information for using MEA for CO2 capture. From search i see various values. 0.13 to 0.2. What is the basis of this? These values look very high in comparison with other amines (DEA, MDEA)...

Hi zznook Check the Bryan Research and Engineering websiter. (www.bre.com) and go to the technical papers section. There they have given data for some commercial units. Ofcourse, you wont find column diameter etc there. but you can calculate them using correlations available in literature...

Hi Although Aspen has bought HYSYS, HYSYS simulation package is as it was before. They are still working separately. Three major simulation engine in this area are: TSWEET, HYSYS and ASPEN ASPEN has some amine property packages which are based on some VLE theories (electrolyte-NRTL...

Hi I have worked with different simulations fro amines. In my experience, ASPEN has not powerful simulation for the same. HYSYS and TSWEET have special packages for amines developed by specialist in that area. Therefore they are more reliable. Do you have these alternative simulations? I...

It is difficult to tell unless we know the composition of a sour gas stream and what are the purity requirements. Can you be more specific about your problem? Like give some more details? What property package are you using in ASPEN? The results are strongly dependant on that. Give some more...

dear 16613 Still your question is not clear. If I understand your information correctly, then you have plant which removes H2S using some amine (which amine?) and now you have to run it for removing H2S and CO2 simultaneously. OK. now what? What information you are looking for? - Have...

The books you have mentioned are probably the most referred ones in the batch distillation area. In my opinion you should stick to them. Prashant

Annie I think it depends on which system you are dealing with. In general, popular softwares for simulation in chemical engineering are 1. Aspen - now aspen has aquired HYSYS but still they are selling it separately. It has got lot of options and can do loads of things (solids...

Jibran it is nice community here and people are ready to help. still i will suggest you that you should compare both options MEA and MDEA. why I am saying it is because.... though MDEA is known for long while, real applications came in large number in last 10 years. Thats what i can see...

Hi I am PhD student working on such kind of problem. Well i have to firtst clarify that i dont have much industry experience and my work is synthesis of such flowsheets. well.. one of the main reason for your client to avoid MEA is it is highly corrosive and also thermodynamically, it is...

friends thanks a lot. i think i have idea how to proceed. thanks again regards Prashant

Dear EGT01 and IRstuff I think you have some experience what i am looking for. Let me explain you in detail what are steps i need. 1. Put input data on spreadsheet. 2. Click button on spreadsheet (some link throuh macro throuh visual basic????? ) 3. This will put this input data for fortran...

Thank you very much for the tips. I will try to use them ans see what happens. regards Prashant

Hi I want to import some data from excel spreadsheet to MSDOS file (or text file). I have some fortran programmes written and got executable file. I want interface with excel. for example.. if i want to change some number in my programme, i will change it in excel spreadsheet and that will...
