Dirty gas means hamful to ambient? or contains contaminates that are not easy to take out?

Hi springmaster
contaminants that will contaminate the oil/system
you would need a purification plant to remove them

In short yes.....
But I would not like to use it because as the Chill mister says it is dirty and wet.
It also contains other gasses that are not what you want in the system.
Refrigerant grade gas is refrigerant grade because it is dry and almost pure quality.
If you use natural gas your system will suffer moisture problems and contamination...
By the time you clean, filter, dry and process the stuff you could have bought the
refrigerant grade for a fraction of the cost and it would work straight from the cylinder.
All the best

If by natural gas you mean ch4 (methane) as all other alkanes (propane, butane, etc...) yes, it can be used as a refrigerant for ultra-cryo temperatures (boiling point -161°C). As said by other, it needs to be purified to refrigerant grade.
