    Abstract: The invention relates to a process for workup of a stream (1) comprising butene and/or butadiene, butane, hydrogen and/or nitrogen and carbon dioxide, comprising the following steps: (a) absorption of the stream (1) comprising butene and/or butadiene, butane, hydrogen and/or nitrogen, with or without carbon dioxide, with a mixture (5) comprising 80 to 97% by weight of N-methylpyrrolidone and 3 to 20% by weight of water to obtain a stream (9) comprising N-methylpyrrolidone, water, butene and/or butadiene, and butane, with or without carbon dioxide, and a stream (7) comprising hydrogen and/or nitrogen and butane, (b) extractive distillation of the stream (9) comprising N-methylpyrrolidone, water, butene and/or butadiene, and butane, with or without carbon dioxide, with a stream (13) comprising 80 to 97% by weight of N-methylpyrrolidone and 3 to 20% by weight of water to separate the stream (9) comprising N-methylpyrrolidone, water, butene and/or butadiene, and butane, with or without carbon dioxide, into a stream (17) comprising N-methylpyrrolidone, water, butene and/or butadiene, and a stream (15) comprising essentially butane, with or without carbon dioxide, (c) distillation of the stream (17) comprising N-methylpyrrolidone, water, butene and/or butadiene into a stream (23) comprising essentially N-methylpyrrolidone and water, and a stream (21) comprising butene and/or butadiene.
