The invention relates to the field of petrochemical engineering, in particular to a combined process and system for producing low-carbon olefin through olefin catalytic cracking. The process comprises the following steps: pretreating a C4 raw material and a light gasoline raw material to remove impurities so as to obtain a pretreated C4 raw material and a first olefin-rich material; enriching the pretreated C4 raw material to change the boiling points of the olefin and alkane to obtain a second olefin-rich material and an alkane-rich material; performing catalytic cracking on the first olefin-rich material and the second olefin-rich material to obtain reaction oil gas; and separating the reaction oil gas to obtain ethylene, propylene and a circulating material. The boiling points of olefin and alkane are changed through enrichment, so that a second olefin-rich material and an alkane-rich material are separated more easily, and the energy consumption of separation is reduced; the concentration ...

The embodiment of the invention provides a carbon emission control method, device and equipment and a storage medium, and compared with the situation that the energy consumption and carbon emission in the refining process are relatively high under the condition that the productivity of a refining enterprise is certain at present, the method comprises the following steps: obtaining carbon emission data and carbon absorption data generated by the refining process in a target historical period; then processing the carbon emission data and the carbon absorption data by using the carbon emission prediction model according to constraint conditions and optimization targets set for the refining process so as to determine target carbon emission data and target carbon absorption data, and finally determining the target carbon emission data and the target carbon absorption data according to the target carbon emission data and the target carbon absorption data. And the actual carbon emission and the ...
