Hi Gents,
I have Aspen Hysys 7.1 version installed on my PC. during simulation whenever i go to quick sizing button in rating tab of the Separator window I always get the Hysys message "Could not size separator; interface request failed". even if i enable the weir. the same problem i was facing in the older version 2006.5. Can any body guide on this whether it is installation related problem or any command is required to fix this. Interestingly the same version of software is installed on my colleague PC but he never faced this problem. Appreciate your response on this.

"Interface" doesn't apply to the physical system (two or three-phase separator) but to the computer code. The software is looking for the separator sizing module and can't find it, so its "request" to the "interface" with the sizing module fails.

If I may give you a tip: don't use Hysys' sizing module. Use a good spreadsheet or calculation method, which you can find, for example, on this website (cheresources.com) and forums. You will know what equations are being used, what the assumptions are, and your results will be more reliable. While convenient, Aspentech's module is opaque and often incorrect, because you'll forget to give it the right parameters. It is not hard to design a separator, as long as you know (or learn) what you're doing.

hi Abid

I found a solution from ASPEn site. let me know it worked for you

There is a dll called sepsize.dll in the Aspen HYSYS installation folder which should be activated as follows:
1. From the Windows Start menu, choose Command Prompt (type 'cmd' >> press enter) to get a DOS prompt. From here one can unregister and register the dlls. Make sure you have full administrative rights to do this.
2. At the DOS prompt, switch to the directory that contains the dll files. For example, if they are located in the same path as the HYSYS default path for sepsize.dll file, your DOS command line will look like: C:\Program Files\AspenTech\Aspen HYSYS 2006>
(Some tips: To switch from a different drive to the C: drive, type in 'C:' at the prompt, and use the 'cd' command to get to the desired directory. To change to the desired folder from default folder, type "cd.." and press enter)
3. Unregister the dll files, At the prompt, type regsvr32/u sepsize.dll and hit Enter. You should get a unregistration success message. Click on OK.
4. Re- register the dlls. At the same prompt, now type in regsvr32 sepsize.dll and hit Enter. You should get a registration success message.
5. Start Aspen HYSYS and check if the 'Quick Size' option works.
