 Abstract
The fractionation processes are the most important processes in Romanian refineries. Usually, these processes are divided in two categories: the binary fractionation processes and the multi-component fractionation processes. The first category has two industrial applications: the ethane - ethylene splitter and the propane - propylene splitter. For these fractionation processes are used many composition control structures. For the second category there are not available the same composition control structures. In this paper the multi-component fractionation processes and the objectives of the specific composition control structures of these processes are studied. Based on this study, the authors had elaborated a specific composition control structure for the butane - butane fractionation process.

 Rezumat
Procesele de fracţionare sunt unele dintre cele mai importante procese din rafinăriile româneşti. În general, aceste procese sunt împărţite în două categorii: procese de fracţionare binară şi procese de fracţionare multicomponent. Pentru procesele din a doua categorie nu sunt disponibile aceleaşi structuri de reglare ca pentru procesele de fracţionare din prima categorie. Autorii au studiat unele procese de fracţionare multicomponent şi obiectivele asociate structurilor de reglare a compoziţiilor pentru aceste procese. Pe baza acestui studiu, a fost elaborată o structură de reglare a calităţii produselor separate, specifică pentru procesul de separare butan-butene.
