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.

Key words: Without natural gas, Distillate oil, Replace, Run a plant

摘要: 中海石油宁波大榭石化馏分油综合利用项目配套的天然气上岛工程因外界原因与项目开工不同步,项目开工存在滞后风险。从开车面临的困难入手,采用外购丙烷、自产液化气、DCC自产丙烷作为天然气的替代介质及制氢原料,增设车用丙烷作为汽化器和LPG罐区至制氢装置供料流程,在重整装置和加氢装置处分别增设两台和一台气化能力为5 t/h的液态烃汽化器,实现了无天然气开工,并对炼油企业燃料气管网设计提出了优化建议。
