Definition - What does Dry Gas mean?
Dry Gas is an alcohol-based additive used in oil and gas engines to restore the combustive power to the water spoiled by gasoline. It is basically a liquid which is added into fuel tanks to absorb the water and keep it in the solution. Most of the gasoline-powered engines run safely up to 10 percent ethanol solution without modification. The engines with 15 percent or above may need a replacement of their fuel lines so that rupture and degradation is prevented.
Petropedia explains Dry Gas
Dry gas is used widely all over the world in the form of feedstock for the petrochemical plants for production of methanol, fertilizer, etc., and fuel for the power plants. It is considered as a clean fuel and is used in combustion as it emits less NOx and CO2 than oil and coal which are the major causes of acid rain and global warming. It also emits less SOx while burning and is also used regularly or semi-regularly to avoid the ill-effects of excess water buildup in the gas tank or gasoline of a vehicle. The electric fuel pumps of the vehicle need to be replaced so as to prevent the ethanol dry rot.
