Of course you can use 97% TEG, nobody in the world can stop you doing this, or maybe your supervisor.
What impact this act will have on your operations... that's another story. But you don't want to know that, right?
I think it's fair: you don't want to give us the details, we don't have the possibility to tell you too much.

mehdi:

Andrei is pointing out some obvious flaws in your post that need to be corrected or improved upon if we are to try to help you.

Andrei - like the rest of us - is trying to help you in your problem, but you fail to give us the necessary details and explain exactly what it is that you want to resolve or ask. We need a clear, understandable description of what you need. We also need an explanation (preferably a sketch or drawing) of the TEG process you are using - complete with process temperatures, pressures, and flows. I have posted a complete TEG PFD complete with heat and material balance in these Forums in an Excel Workbook. Search for it and you will see what I mean.

I don't believe you mean to ask if you can use 97% TEG for drying natural gas. What I believe you mean is: "Can I use 97% lean TEG to dehydrate a X MM Scfd steam of natural gas at Y psig and Z degrees F in order to obtain a dew point (or water content) of W lb/MM Scf?" "The process I am using is described in the attached PFD".

If the above is what you really mean, than why don't you state it? We need all the help and data we can get from you if we are to help you out.
