  Subject : Diesel Hydrotreating
  Lets suppose the feed to DHT unit has both Naphtha (C5 to 125 degree C) (4 wt%) and Diesel (125 degree C plus) (96 wt%), which will be treated for < 10 wppm Sulfur in Diesel. What would be the expected yields of Naphtha and Diesel in the product?

I believe because Naphtha is SR material it will not get enough volume swell and hence its yields in the product will remain the same as that of feed.
