Übersetzung für "Saure gase" in Englisch

However, a high specific regeneration energy is correlated with the high affinity for acid gases.

Specific impregnations distinctly increase the filtering activity for certain acidic or basic gases.

In oil and gas exploration, wellbore fluids often contain acid gases and chlorides.

The Pt catalyst used as gaskmask filter material offers, particularly, but little protection additionally against acid gases.

Acid gases are titrated with NaOH and basic gases with HCl in the usual manner.

The absorbent according to claim 1 which additionally comprises a physical solvent for acid gases.

Wet scrubbing systems provide the highest removal efficiencies for soluble acid gases of all flue-gas desulphurisation (FGD) methods with the lowest excess stoichiometric factors and the lowest solid waste production rate.

Pollutants are found in the intake fresh air in particular with high traffic densities and such pollutants include for example hydrocarbon compounds, nitrogen oxides, acid gases (for example sulfur dioxide and other sulfur compounds as well as carbon dioxide).

Due to the presence of a salt-type bond from CO2 and NH3 in the laden washing liquid containing acidic gases in the bottom of the washing column, the solubility of hydrocarbons is considerably lower therein, without however influencing the ability for absorption of the disadvantageous CO2 acidic gas therein.

In addition, the completely exposed, colorless background of a film copy produced by means of the two-component diazotype material of the invention is bathochromically shifted to yellow by rconversion of the benzothiazole dye salt, under the action of an acid medium, for example, an acid gas or an acid solution.

It is already known to use acrolein to deodorize aqueous systems by the removal of hydrogen sulfide and by the combined effect with carbon dioxide to prevent or to hold as small as possible the corrosion on metals by acidic gases.

Acid or basic gases are preferable, which can be, for example, oxygen compounds with carbon, nitrogen and sulfur, and/or hydrogen compounds of nitrogen, and/or nitrogen-organic compounds, such as amines.

Due to the presence of a salt-type bond from CO2 and NH3 in the laden washing liquid containing acidic gases in the bottom of the washing column, the solubility of hydrocarbons is considerably lower therein, without however influencing the ability for absorption of the disadvantageous CO2 acidic gas therein.

It is known, in practice, that sulfuric acid corrodes the reactor walls under the reaction conditions as well as gives off acidic gases.

It is also possible to introduce acid gases such as HCl or SO2 directly into the aqueous reaction mixture.

The sewage which contains a condensate of the product gas is passed through a plurality of coarse purification stages to remove tars, oils, phenols, acid gases and ammonia.

It is already known to use acrolein to deodorize aqueous systems by the removal of hydrogen sulfide and by the combined effect with carbon dioxide to prevent or to hold as small as possible the corrosion on metals by acidic gases.

But the CO filters containing platinum metal and having become known to date represent no or only little protection, particularly against acid gases like chlorine, hydrogen cyanide, hydrogen sulfide and similar gases.

SUMMARY OF THE INVENTION The invention provides a Pt catalyst on a substrate as an air purification means for use in air filters so that a single-layer and, hence, smaller and lighter filter filling becomes possible, which is effective against CO and against acid gases also.

Basic additions, such as lime, can also be added to the feedstock in order to trap the acidic gases formed during the low temperature carbonization process.

Acidic gases, for example sulfur dioxide, which circulate in the reactor during production of the monomers have proved to be particularly effective in this regard.

Such an impregnated filter meets the performance specifications of DIN 3181 for type B filters against acidic gases and type K filters against ammonia.

It has been discovered that the addition of conventional humectants can lead to losses in the absorption capacity for acid gases of the absorber, and to a reduction in abrasion resistance.

The object of the invention is to provide absorption material for acid gases, without the disadvantages of the prior art and, in particular, on the one hand, providing water and, on the other hand, binding water, and being storage-stable, i.e., the absorption performance of the absorber over the storage period is maintained, without loss of CO 2 absorption capacity.

If the natural gas to be treated in the second absorption stage contains hydrogen sulfide and carbon dioxide as acidic gases, these two gases can be removed together in the second absorption stage.

Since acid gases are able to attack metals, polyarylene sulphides having such characteristics should not be left in contact with metals for any appreciable time at high temperatures.

Efficient filtering system, listed according to their particle size distributions, adhere to the ASTM standard, effective for acid gases and organic gases adsorption capacity, uses a high efficiency HEPA filter for particles, particles larger than 0.3um, filtration efficiency up to 99.995%.

The present invention therefore relates to a process for deacidifying a fluid hydrocarbon stream which comprises CO 2 and/or other acid gases as impurities in which the fluid stream is brought into intimate contact with an absorption liquid in an absorption or extraction zone, so that CO 2 and other acid gases present in the fluid stream are absorbed by the absorption liquid, the substantially purified fluid stream and the absorption liquid which is loaded with CO 2 and/or other acid gases are separated from one another, and the absorption liquid is subsequently regenerated and then again fed to the absorption or extraction zone.
