Control - on-line analyzers of the gas compostion.

Liquefication - mostly the concentrations are very low, thus it will be not economically effective. There are some approaches like absorption/scrubbing or biofilters - this way you can "trap" the pollutants in the liquid absorbent or as a source of biomass or product of the compounds bio-degradation.

Dear Grzegorz,

I thank you.

Following your answer (1), yes, we can use on-line analyzers for knowing the gas composition. But how can we minimize to be 0% gas emissions from the industry? I mean., if we don't need any gas emission to the environment, what kind of system can we use?

Following your answers(2), after the pollutants adsorbed, do you means the other left will be disposed to the landfill or....?

Yonas,

As I understand your point of view -> control=minimize to 0% (?)

G

This is very general question.

What are those emissions/pollutants?

SOx, NOx, CO2, ....?

Murtaza,

Thanks.

Mohammad,

You are right, it is general question. But I am looking general methods if there are known methods to minimize the gas emissions from industry (e.g Cement factory).
