Has anyone had trouble with "one or more feed not solved" on RefSys, template Hydrocracker? I need to simulate a HDS unit for cat cracked naphtha, but I always have problem with the feed. The default feed type in Library (Feed Data tab) is too heavy for naphtha, and it not contains C4, C5. What should I do to solve that problem? How can I create another Feed Type instead of that default? I made a chromatography for my feed, but when I modified lump weight percents conform my chromatography, it didn't work.
