Abstract: The natural gas project supported by CNOOC Ningbo Daxie Petrochemical Co., Ltd. distillate comprehensive utilization project was not synchronized with the start of the project due to external reasons, and there was a risk of lagging behind the start of the project. Starting with the difficulties faced by the start-up process, this study uses propane purchased from outside, self-produced liquefied gas, DCC-produced propane as an alternative medium for natural gas and raw materials for hydrogen production, and adds vehicle propane as the carburetor and LPG tank area to the hydrogen supply process. In the reforming and wax oil hydrogenation installations, 2×5 t/h and 5 t/h liquid hydrocarbon carburetors were added separately to achieve the start of natural gasfree operation, and optimization suggestions were made for the design of the fuel gas pipeline network for refineries.
