There is an pipeline to dispatch VGO from COT to Dispatch area (Jetty line). Once the dispatch is over, this line will be filled with HSD High Speed Diesel to avoid the congeal of VGO in that line and while the loading of VGO starts again it'll be pumped to a tank, if the loading of VGO is over HSD will be pushed back in the line. Now the problem is with the quality of this HSD. Its properties have been changed. So can anybody tell me what we can do with this HSD. The options which I know are : Reprocessing Or using any additives to improve its quality.....Is there any other option???? And also please list out the additives which can be used; Thanks in advance.
