When carbondioxide gas mixes with R404A inside the refrigeration system,how can i remove Co2 gas from R404a?,Are they compartible?,which one is lighter?

Co2 will never condense in a R404a system, so I would expect you could purge it from top of condenser or liquid receiver.

But does can partially react with R404A forming a new substance?

Not that I know of. CO2 reacts with fluorine, but not with fluorinated compounds. They are quite stable.

It sounds strange but I'm told in Ausi we don't have to reclaim co2. However if purging from the condenser (once gas has settled) will be a mixture of gases - so it will need to be purged into a large empty cylinder.
Very strange isn't it co2 emissions.
That's how to get it out but how did it get in? As for the mixing I believe it would mix in vapor form only but not become homogeneous. Just like air and a press temp chart will indicate how much is in the system.

Well, yes, the best would be to reclaim the whole amount of refrigerant and dispose of it. But that's easy.
I thought the original poster wanted a shortcut.

well gents , I thought that the whole amount of gas would have to be reclaimed and incinerated ,
yes, how did the gas get mixed ?
sedgy, come on paul h
