Separating at least one trace component of feed fraction, preferably hydrocarbon rich fraction comprising main component methane, comprises adsorptive drying and adsorptive removing of trace components, and regenerating by regeneration gas

摘要

Separating at least one trace component of a feed fraction (1), preferably a hydrocarbon rich fraction comprising the main component methane, comprises: (a) adsorptive drying of the feed fraction; (b) adsorptive removing of the trace components from the dried feed fraction (2); (c) carrying out the adsorptive drying and/or the adsorptive removal of trace components in at least two parallel adsorbers alternately passing through adsorption- and regeneration phase; and (d) regenerating the adsorptive removal unit for trace components by a regeneration gas (5). Separating at least one trace component of a feed fraction (1), preferably a hydrocarbon-rich fraction comprising as the main component methane, where the amount of each trace component in the feed fraction is of 1000 ppmV, comprises: (a) adsorptive drying of the feed fraction; (b) adsorptive removing of the trace components from the dried feed fraction (2); (c) carrying out the adsorptive drying and/or the adsorptive removal of trace components in at least two parallel adsorbers alternately passing through adsorption- and regeneration phase; and (d) regenerating the adsorptive removal unit for trace components by a regeneration gas (5) which is to be removed at a concentration of up to 2 ppmV.
