RE: feed stock changes



Dear Mr. Garyville,

I understand that you had problems while processing Low Asphaltenic VR feed in your Coker. Could you please explain the problems you had faced in ur drums during Low Asphaltenic VR feed processing?. Were there any problems on Hot spots in drums, Coke Splillage, Blocking / plugging of bottom nozzles, etc.

Could you please also share what was the typical Asphaltene (C7 Insoluble) content in VR below which you had faced these problems in your drums.

I would be glad if you could also share what was the typical Crude slate which was being processed in ur refinery during this period of problem.

Thanks & Regards

D.P. Prasanna
