Abstract: Disclosed is a method for processing naphtha, according to which a) naphtha or a stream generated from naphtha in a preprocessing step is divided into a stream A that is stripped of aromatics and a stream B which is enriched with aromatics in a membrane unit, the aromatics concentration in stream A ranging from 2 to 12 percent by weight (step a); b) partial stream A is directed at least in part into a steam cracker (step b); c) partial stream B is directed at least in part into a unit in which said stream B is divided into a stream C or several streams C' C'', C''',..., which has/have a lower aromatics content than stream B, and a stream D or several streams D', D'', D''',..., which has/have a higher aromatics content than stream B, by means of a thermal process (step c); d) stream C or at least one of the streams C', C'', C''' is delivered as a whole or in part to the feed for the steam cracker or directly to the steam cracker (step d).

Abstract: Procedimiento para la separación de nafta, en el que a) se separa nafta o una corriente de nafta, generada en una etapa de tratamiento previo, en una unidad de membrana, en una corriente A, empobrecida en hidrocarburos aromáticos y en una corriente B, enriquecida en hidrocarburos aromáticos, siendo la concentración de los hidrocarburos aromáticos en la corriente A desde un 2 hasta un 12 % en peso, b) la corriente parcial A se envía, al menos en parte, hasta una unidad de craqueo con vapor, c) la corriente parcial B se envía, al menos en parte, hasta una unidad, en la que se separa, por medio de un procedimiento térmico, en una corriente C empobrecida en hidrocarburos aromáticos, frente a la corriente B o en varias corrientes C'', C", C"'', ... que presentan, respectivamente, contenidos en hidrocarburos aromáticos menores que la corriente B, y en una corriente D enriquecida en hidrocarburos aromáticos, frente a la corriente B o en varias corrientes D'', D", D''", ... que presentan, respectivamente, contenidos en hidrocarburos aromáticos mayores que la corriente B, d) la corriente C o bien al menos una de las corrientes C'', C", C"'' se alimenta, respectivamente, en su totalidad o en parte, a la alimentación de la unidad de craqueo con vapor o a la propia unidad de craqueo con vapor.

Abstract: Process for the work-up of naphtha, wherein a) naphtha or a stream produced from naphtha in a pretreatment step is separated in a membrane unit into a stream A which is depleted in aromatics and a stream B which is enriched in aromatics, with the aromatics concentration in stream A being from 2 to 12% by weight (step a), b) at least part of the substream A is fed to a steam cracker (step b), c) at least part of the substream B is fed to a unit in which it is separated by means of a thermal process into a stream C which has a lower aromatics content than stream B or a plurality of streams C', C'', C''' . . . which each have lower aromatics contents than stream B and a stream D which has a higher aromatics content than stream B or a plurality of streams D', D'', D''' . . . which each have higher aromatics contents than stream B (step c), and d) the stream C or at least one of the streams C', C'', C''', in each case in part or in its entirety, is added to the feed to the steam cracker or fed into the steam cracker itself (step d).
