What i made works very good... may be confusing as i'm newbie in coding but it's doing exacly what i wanted.
It's not loading bobs and vanilla recipes lua files when angels refining is detected, but if there is no angels petrochem it's additionally loading vanilla oil recipe (that oilonly file in petrochem compatibility lua) or if there is petrochem, it's loading petrochem barells recipes.
What i didn't made are techs and this thing that limit productivity modules you have on things you made.
