Sprawozdanie z projektu technologicznego

PN 10:15, nr grupy: 11

Strumień 1 zawierający surowiec o składzie masowym: 0.587 benzenu, 0.333 toluenu, 0.06 o-ksylenu i 0,02 tiofenu o przepływie 80 kmol/h kierujemy do miksera, gdzie łączy się ze strumieniem 16 zawierającym zawracany toluen w ilości 63 kmol/h. Następnie strumień 15 wychodzący kierujemy do kompresatora, gdzie sprężamy go do ciśnienia 60 bar. Równocześnie postępujemy podobnie ze strumieniem 6 zawierającym wodór w ilości również 80 kmol/h. Oba strumienie trafiają do oddzielnych wymienników ciepła, gdzie są podgrzewane do temperatury procesu 627 ^oC. Strumienie łączą się w reaktorze, gdzie zachodzi główna reakcja chemiczna procesu. Strumień 3 wychodzący kierujemy do kompresora 10, gdzie zmniejszamy ciśnienie do 17 barów. Strumień 12 przechodzi do wymiennika ciepła chłodzonego wodą i do temperatury 35^oC. Strumień 4 wprowadzamy do kolumny typu flash. Strumień 11 wprowadzamy do kolumny destylacyjnej 9 i jest rozdzielany na strumień 14 zawierający gotowy produkt benzen i strumień 13, który wchodzi do kolumny destylacyjnej 12 i jest rozdzielany na strumień 16 (czyli zawracany toluen) i strumień 18 zawierający gotowy produkt – difenyl.

Wnioski:

Instalacja pracuje wydajnie. Ze strumienia surowca 80 kmol/h udaje się uzyskać benzen w ilości 75 kmol/h. Kolumna destylacyjna 9 ma 40 półek teoretycznych, a 12 – ma 8, więc nie są zbyt wysokie. Można by było rozdzielić rozdzielanie na 3
