Isothermal Compressor?

My prof. gave us a problem about exergy analysis of an isothermal compressor. It was something like this '' A Hydrogen isothermal compressor that requires 100 KWatt , 10% of its power is to overcome friction.'' the rest is not important my question is : Is it possible for such a device... show more My prof. gave us a problem about exergy analysis of an isothermal compressor.
It was something like this '' A Hydrogen isothermal compressor that requires 100 KWatt , 10% of its power is to overcome friction.'' the rest is not important

my question is : Is it possible for such a device '' isothermal compression''??
And one of the requirements was the heat loss to the surroundings??
((According to the first law Q=W since t=const. so does that mean that the input power to the compressor will all be lost to the surroundings???
I'm really stuck .... help please
