Abstract
This process for the transportation of a batch of naphtha in a pipeline, the prime purpose of which is to transport crude oil, is characterized in that the batch of naphtha, bracketed by batches of condensates, namely a head batch of condensate and a tail batch of condensate, is conveyed in the pipeline and, on arrival, the batch of naphtha is recovered between a point in time at the earliest at the end or substantially at the end of the passage of the head condensate/naphtha interface region and a point in time at the latest at the beginning or substantially at the beginning of the appearance of the naphtha/tail condensate interface region.
Claims15
A process for the transportation of a batch of naphtha in a crude oil pipeline, comprising the steps of:
- (a) conveying crude oil feed in said crude oil pipeline;
- (b) conveying upstream of said crude oil in said crude oil pipeline, a head condensate;
- (c) conveying a batch of naphtha, in said crude oil pipeline, upstream of said head condensate, forming a head condensate/naphtha interface region;
- (d) conveying a tail gas condensate, in said crude oil pipeline upstream of said naphtha, forming a naphtha/tail gas interface region;
- (e) conveying a crude oil feed in said crude oil pipeline upstream of said tail condensate;
- (f) on arrival at a recovery site, locating the head, gas/naphtha condensate interface region, and thereafter recovering the upstream batch of naphtha.
