Thermal Cracking Process
Thermal Cracking Process ( Proses Perengkahan Termal)
Proses perengkahan thermal (thermal Cracking) adalah suatu proses pemecahan rantai hydrocarbon dari senyawa rantai panjang menjadi hydrocarbon dengan rantai yang lebih kecil melalui bantuan panas. Suatu proses perengkahan thermal bertujuan untuk mendapatkan fraksi minyak bumi dengan boiling range yang lebih rendah dari feed (umpannya).
