Fuel Gas Treatment

Which metals?

Yes. It's called a fuel filter.

Every gas pump I've ever used has one in the hose, so the fuel is filtered before it goes into my car's gas tank.

Plus there is one in the fuel line in every car I've ever driven, so the fuel is filtered one last time before it gets to the carburetor or fuel injection system.

Wrong type of gas......this is not petrol, its natural gas.......not a fluid.

As I understand it, fluid includes gas and liquid (at least, maybe plasma as well).

For the benefit of the reader in the North American continent, please clarify whether the term <...gas...> refers to a substance that is neither solid, liquid nor plasma, or whether it refers to the substance, the full name of which is known as "gasoline" there?

There shouldn't be any solid, metal or otherwise in natural gas. How did it get in? Do you mean metallic elements or compounds? If you know the particle size it shouldn't be too hard to source a filter that will remove it.

A filter would work, but there is too little information provided to be any more specific.

Thank you all for your valuable replies. My sincere appologies for not providing the complete data.

The fuel gas used is Natural Gas for buring in Gas Turbines to produce power. I was curios to know if the trace metals like: Pb, Zn, Na, Vanadium, Calcium, Magnesium, etc can be removed. if yes what is the process by which it is done.

My appologies again for providing insufficient data.

What are the levels of these metals in the gas and the particle sizes? Is this smoke? Is the level parts-per million? Parts per billion?

What other data hasn't been provided yet that could help the forum come to some understanding of the nature of the problem and offer some solutions, and why has this data not been provided up-front?

Dear PW Slack

I have no levels. the fuel gas analysis actually received by me shows no presence of these trace metals. however i wish to know if there were any traces is there any method to remove it or not. Guess nothing further is there to hide.

In the plants where the company I work for has boilers and gas turbines, all of them operate on natural gas. Typically this gas is processed in the field at a "cryo" plant to remove other valuable hydrocarbons (slightly lowering the BTU value of the gas), and this "cryo" plant seems to remove nearly all other impurities of the type you mentioned. We do filter the gas that is carried over our own pipeline, since a brilliant engineer (certainly not me) decided to use city tap water to hydro test the pipeline, and now there are certain shall we say, corrosion issues. I suppose that nearly any typical gas turbine should have fuel filtration as part of the fuel system, just as an insurance policy to protect the fuel jets from clogging in the burner cans, not to mention potential damage to turbine blading.

Thanks Stewart,

however can you elaborate a little on the process as to how these are removed.

A cryogenic plant operates by compressing and expanding the gas through an expander that results in a tremendous lowering of temperature (incoming gas or compressed gas is later used to warm this back up to a suitable temperature). This "cryo" process removes so-called "white gas" components such as C2-C6, water, and other gases. Filtration aspect is usually done at the point of use. Consult with turbine manufacturer about this requirement.

In that case, don't worry, chicken curry.
