Verfahren zum Transportieren von Naphta in einer Rohölrohrleitung

摘要

Naphtha is transported using a pipeline also used for transporting crude oil. The naphtha is supplied to the pipeline in batches preceded and followed by batches of condensate. At the receiving end the pipeline each bath of naphtha is recovered after the leading interface of naphtha and condensate arrives and before the trailing interface arrives. An Independent claim is included for the naphtha supplied to and recovered from a pipeline as above. Preferred Features: The condensate is distilled from crude oil or natural gas between 30 degrees C and 200-350 degrees C. Each batch of condensate is≥1500 m<3> and preferably≥4500 m<3>. The batches of condensate need not be the same size. The naphtha/condensate interfaces are detected by a densitometry and/or a colorimeter.
