Shell Global Solutions International has announced that they have successfully developed a new catalytic cracking (FCC) process that can increase diesel and propylene yields.
This medium-distillate oil and lower olefins selection process (MILOS) increases the diesel and propylene yields simultaneously by adding risers during the rebuild or new construction of the FCC unit. The MILOS process is particularly attractive to petrochemical refiners. In addition, due to greater operational flexibility, the MILOS process can help refiners adjust operations based on seasonal needs.
According to reports, the traditional FCC process can no longer meet the current market demand for reduced gasoline, diesel and propylene demand, and MILOS can help refiners to meet the current market demand. With this new process, refiners can operate FCC units in different modes. In the propylene mode, compared with the traditional FCC unit, the plant propylene production can be doubled and the traditional diesel yield and quality can be maintained; in the diesel mode, the plant diesel production can be increased by up to 20% and the cetane number can be increased by 7 units. , And propylene production increased. By changing the operating parameters, the new FCC process can be operated in any mode and can also be switched to the traditional mode.
