Abstract
Provided is a method for preparing synthesis gas, and more particularly, a method for preparing synthesis gas including: supplying a pyrolysis fuel oil (PFO) stream including a PFO and a pyrolysis gas oil (PGO) stream including a PGO discharged from a naphtha cracking center (NCC) process to a distillation column as a feed stream (S10); and supplying a lower discharge stream from the distillation column to a combustion chamber for a gasification process to obtain synthesis gas (S20).
Claims16
A method for preparing synthesis gas, the method comprising:
- supplying a pyrolysis fuel oil (PFO) stream including a PFO and a pyrolysis gas oil (PGO) stream including a PGO discharged from a naphtha cracking center (NCC) process to a distillation column as a feed stream (S10);
- and
- supplying a lower discharge stream from the distillation column to a combustion chamber for a gasification process to obtain synthesis gas (S20),
- wherein the lower discharge stream from the distillation column has a kinematic viscosity at the time of supply to the combustion chamber of 300 cSt or less, and
- wherein the lower discharge stream has a flash point higher than a temperature at the time of supply to the combustion chamber by 25° C. or more.
