You may use this link to download the books (www.pdfdrive.com/) For reference/journal use may use sci-hub website

You may use design spec function (vary the length of the reactor to get target conversion. Hope this helps

not sure though...maybe u can..u need to review your thermodynamic property n see whether it is accurate or not to represent liquid phase as well

Hello, I have never tried it so far. But what you can do is use a series of interconnected RGibbs (maybe 5 or 6 block) and enter feed into reactor 1 and another feed enter at reactor 5 (or six). Maybe this link help. Hope I answer your question books.google.com.my/books?id=WDVldP9YUPkC&pg=PA254&lpg=PA254&dq=counter+current+reactor+aspen&source=bl&ots=zd3Y55KuLR&sig=ACfU3U0qFIxXSPDtjH48BVut5Uhi8SBCXg&hl=en&sa=X&ved=2ahUKEwjmicHW64PqAhV1muYKHRsbDJYQ6AEwCXoECAgQAQ#v=onepage&q=counter%20current%20reactor%20aspen&f=false

@@jabatankejuruteraankimiada4612 Thank you for your response. Basically, I was asking this due to that reference and I cannot change it to a counter-current reactor.

@@LeakIrengNow that I think about it, you might be right..ok then, how about you put component separator in between the RGIBBS to separate the species (output of RGIBBS) prior entering the next block..?

@@MohamadReziAbdulHamid Nope, it doesn't work. I tried it and the RGIBBS can only receive input as cocurrent (1 side only). [It seems that I misinterpreting the reference. In a series of RGIBBS, output from the next reactor can be used as input for previous reactor. That, will make it as countercurrent.]

I general yes..but I prefer Radfrac because I can size the column and get all the dimension (e.g., diameter, tray distance, type of trays, weir height, etc.) and many other things..I use DSTWU first to get initial guess of the condition before i use radfrac..Hope this helps
