Gas group and temperature rating of Hydrocarbon
Gas group and temperature rating of Hydrocarbon
(OP)
I'd like to select electrical equipment to be installed in area where "hydrocarbon" exists. I have no idea which gas group and temperature rating it belongs to.
Anybody helps me out ?

Tar is a hydro-carbon.
Lubricating oil is a hydro-carbon.
Diesel fuel is a hydro-carbon.
Gasoline is a hydro-carbon.
The term "hydro-carbon" is often used in the petroleum industry to refer to a mixture of products, or to a hydro-carbon based liquid of unknown or uncertain composition.

You will also need the likely duration of when a hazardous gas will be present in order to determine whether it is a zone 0, 1, or 2. This can be calculated from the nature of the equipment and its operating conditions.
If you assume worst case for everything you will end up with a very restrictive design spec which will only allow intrinsically safe 'ia' design. In most cases this will be completely unacceptable, which brings up my earlier point: find out what you are designing for. You don't have enough information at present.
