[0007] Although my country has made some progress in petrochemical simulation, energy saving and optimization, the scope of application is not wide, and most of the devices are far away from the original design conditions due to old and pending renovation and some devices have undergone capacity expansion and transformation.
At the same time, due to the characteristics of petrochemical and oil refining industries with complex processes, many operating parameters, changing working conditions and greatly affected by changes in the external environment, the current adjustment of parameters is mainly based on the experience of the team members, and the analysis of data is mainly based on hand calculation

The invention provides an energy optimization analysis method for a chemical engineering device. The energy optimization analysis method comprises the following steps that a simulated heat exchange network of the chemical engineering device is established, and the simulated heat exchange network is transformed through a pinch technology; a simulation process of the chemical engineering device is established, and the simulation process is optimized through energy analysis; reaction waste heat produced by an exothermic reactor in the chemical engineering device is recovered in an optimized mode. According to the energy optimization analysis method, the simulated heat exchange network is transformed through the pinch technology, the simulation process is optimized through the energy analysis, and the reaction waste heat produced by the exothermic reactor in the chemical engineering device is recovered in the optimized mode. Therefore, simulated energy saving under the whole plant conditions is achieved.
Description
technical field [0001] The invention relates to the field of chemical industry, in particular to an energy optimization analysis method for a chemical plant. Background technique [0002] The petrochemical and oil refining industry is an important part of petroleum processing and production. Its process flow is complex, energy consumption is high, and operating conditions are changeable. As people pay more and more attention to energy and environment, the analysis, energy saving and optimization of petrochemical and refining process systems are imminent. [0003] At present, simulation technology has achieved obvious results in energy saving and optimization in the petrochemical industry, and has been increasingly valued around the world. For example, United Carbon, DuPont, Monsanto, ICI, etc. have already adopted simulation analysis technology. Large engineering design companies such as Kellogg, Lummus, Kanshirota, etc. have all set up simulation analysis technology groups...
