OPTIMIZATION OF PRODUCTION AND OPERATION PLAN OF REFINERY UNDER THE SITUATION OF"DUAL CARBON CONTROL"
With the steady progress of"dual-carbon"strategy in China,the new situation of shifting from"dual-control of energy consumption"to"dual-control of carbon emission"has put forward higher requirements for energy conservation and carbon reduction in the petrochemical industry.From the perspective of the key link of petrochemical industry chain—production,operation and planning optimization,this study explored a new way to reduce carbon emission by optimizing production scheme without changing the existing production process and energy structure and increasing additional investment.By combining the carbon emissions from the production process of a refining-chemical integrated enterprise A and a fuel-based enterprise B,and innovating the calculation method of indirect emission factors,the carbon emissions from each set of units of the enterprise was accurately calculated,the accuracy of carbon emissions measurement of refineries was advanced from the whole-plant level to the level of units.Furthermore,the carbon emissions of the plant was incorporated into the production planning optimization model,and the influence of carbon emissions of the plant on the enterprise planning optimization was investigated,and it was found that there was a space for optimizing the carbon reduction of at least 3％under the conditions of no change in the crude oil processing volume and ethylene production,which provided practical solutions for carbon emission reduction of enterprises A and B in the actual production.
