My is Djaroulaye and I am a student at Avans Hogeschool. For a school project, we need to perform a comparative LCA about traditional oil refinery versus the oil recycling process. The databases we found didn't have the specific steps for all the processes that happen in an oil refinery. For example the specific step 'atmospheric distillation'. Is there a database that has these steps or is it possible to manually add them to an existing database?
