Übersetzung für "Acid scrubber" in Deutsch

Uncondensed vinyl acetate monomer is scrubbed out in an acetic acid-operated scrubber.

The first acid-operated scrubber 8 has a scrubber circulation 18 with a water feed 19 .

It is possible to install this unit alone or in connection with an acid gas scrubber of any type desired.

The H2 S-laden liquor was taken off at the bottom of the scrubber column and recycled by means of pump 24, through line 25, to the degassing stage of the acid gas scrubber 23.

Pure methyldiethanolamine liquor (40% strength) coming through line 22 from the degassing stage of the acid gas scrubber 23 of the synthesis gas plant, trickled in counter-current to the gas in the column.

These dedusting stages comprise a dust collector 7, for example a woven filter or an electrostatic filter, for separating fly ash 15, a first acid-operated scrubber 8 (pH?1) for separating hydrochloric acid 16 and a second neutral or slightly acid-operated scrubber 9 (pH?7) for separating SO 2 (discharge of ammonium sulphate and ammonium sulphite 17).

In the first acid-operated scrubber, at pH values of preferably less than 1, hydrochloric acid can be selectively separated by absorption in water, without sulphur dioxide being separated.

Since dust-form constituents of the crude gas are deposited in the sulfuric acid in the scrubber 2, a partial stream 12 is run off from the system in accordance with the invention and filtered or otherwise separated from solids to avoid problems through accumulation of the solids.

The gas is cooled to 48°-55° C. by scrubbing with 5-25% sulfuric acid in a scrubber 20.

This line, to be built in parallel with the two existing ones, will again consist of a grate, boiler and three-stage flue gas cleaning plant made up of a dry stage (fabric filter), a two-stage scrubber (acid and gypsum scrubbers) and a DeNOx plant (catalyst).

As a result of the raw gas compression 2 a, the raw gas is heated in such a manner that cooling is necessary before the acid gas scrubber 3 (which is not shown).

Uncondensed product, essentially ethylene, CO 2 and vinyl acetate, is withdrawn at the top of the preliminary dewatering column and is extracted by scrubbing in an acetic acid-operated scrubber (cycle gas scrubber).

In the CO conversion the carbon monoxide contained in the synthesis gas is converted by the addition of water steam into carbon dioxide by adequate processes, which can subsequently be removed from the synthesis gas by treatment in an acid-gas scrubber, for example.

If the portion of gases to be adsorbed is low, it is normally sufficient to provide a pressure swing adsorption unit without an upstream acid gas scrubber.

Hall air and exhaust air from the tunnel drying are purified via an acid scrubber and biofilter.

Acid scrubbers produce solutions containing hydrochloric acid, that are contaminated by a number of heavy metals.

Constructed in parallel with the two existing lines, the new line will be made up of a grate, boiler and a three-stage flue gas cleaning system in the form of a dry stage (fabric filter) and two wet scrubbers (acid and gypsum), followed by a (catalyst) deNOx plant.
