摘要： An optimization method and system for a whole process of molecular-level oil refinery processing and a storage medium are described. According to an embodiment, for mixed products obtained by prediction from simulation of a molecular-level crude oil processing process, when physical properties of any mixed product do not meet any preset standard, or when a target parameter of the mixed products does not meet a preset condition, the proportion of different fractions entering respective petroleum processing device, an operating parameter in a product prediction model, and a mixing rule for mixing predicted products are adjusted, and the mixed products are re-obtained, until the product properties meet any preset standard and the target parameter meets the preset condition. Final predicted products are predicted by adjusting the proportion of fractions for secondary processing, and the production efficiency is improved by means of the simulation optimization of a production process.

摘要： A method and a system for the real-time optimization of a molecular-level device, and a storage medium are described. The method includes: inputting molecular composition of petroleum processing feedstocks into a pre-trained product prediction model to obtain a predicted molecular composition of corresponding predicted products and a predicted molecular content of each single molecule; determining whether the predicted product meets a preset standard for a target product; if the predicted product does not meet any preset standard for a target product, adjusting an operation parameter in the product prediction model, to re-obtain the predicted molecular composition and the predicted molecular content, until the preset standard is met. By means of the present disclosure, molecular-level integral simulation and real-time optimization of the molecular-level device from the feedstocks to the product processing process are achieved, and the precision and production efficiency are improved.
