Yes, but the procedure is a highly specialized one and theere is lots of potential for problems. Kids, DON'T try this at home. This is a problem that should be taken to a trained professiobnal conservator.
Prescriptions such as the ones below coming ftom people like us who are not experts in this field but have just heard about a procedure are neither responsible nor ethical. I recall the destrcution of a valuable fossil specimen by a gentleman who heard about a procedure but could not be bothered to look it up, with the result that a compound which should have been applied in vapor phase was used in a whole-bath solution. No more problem. No more fossil.
There is not enough information here to do our colleague in Brazil much good and potential for a lot of harm. Instead of second-guessing, trying to re-create procedures from memory or otherwise act outside our own expertise, why not take the time tro find out who specializes in this sort of thing and steer our colleague in the right direction?
By the way, another post referring to US law was incorrect. Mummies are considered to be international heritage under several treaties and conventions, and their legal status is very different from that of natural history specimens. The Getty Conservation Institute has done a lot of work with this issue. Chances are, people on this list haven't.
The techniques that work with flooded material under one set of circumstances may destroy it under another. Please take the time to find an expert in the field. You wouldn't want an archaeological conservator telling people how to manage natural history collections, right? The drying described below may not be fast enough to prevent biodeterioration. Find the people with the answers.

Taxacomers --
I agree with this prescription -- it is no joke. Stanford sought to save an enormous number of books that were flooded a few years ago, and it went to NASA/AMES to find a vacuum chamber big enough to take big batches of books at a time, and did just this procedure, and it worked.

Dear Paulo,
I am wonder if you have large vacuum chamber available. Put mummy onto 5 cm strong layer of silicon granules (used to keep instruments dry) and slowly decrease of air pressure. Repeat three times.
