Abstract:

This paper analyzes the energy consumption structure, CO₂ emission and carbon emission intensity of a fuel refinery in the past three years, and the action plan for carbon peaking and carbon neutrality is put forward. By analyzing the application prospects of low-temperature heat comprehensive utilization technology, carbon capture and utilization technology, photovoltaic power generation technology, heating furnace optimization, green hydrogen energy construction and CO₂ utilization and conversion technology, the refinery strives to control the total carbon emissions within 800 kt, CO₂ emission intensity within 0.16 t/t, and terminal electrification rate to around 15% by the end of the 14th Five Year Plan. This will explore energy-saving and emission-reduction paths for the energy structure adjustment of fuel based refineries, provide development ideas for the low-carbon development and transformation of refining enterprises, and ultimately achieve the transformation of fuel based refineries into “oil, gas, heat, electricity, hydrogen” comprehensive energy companies.

Key words: fuel based refinery, low-carbon development path, steam cascade utilization, photovoltaic power generation, optimization of heating furnace, oxygen rich combustion, green hydrogen energy, comprehensive utilization of low temperature heat
