A refinery process energy consumption analysis method and device

Abstract

The invention provides a refinery process energy consumption analysis method and device. The method comprises the following steps: calibrating relevant data; taking the calibrated data as reference working condition data; taking the calibrated process operating parameters as basic data for establishing actual energy model; establishing an actual energy model to verify the actual energy consumption; according to the calibrated throughput and product yield, Under the condition of satisfying the preset quality requirements of the product, by using the optimized process and equipment operation data, the operation conditions of the lowest energy consumption of the catalytic reformer can be determined, the relevant calculation regulations are carried out, the theoretical energy model is established, and the theoretical energy consumption is simulated and calculated according to the theoretical energy model established; according to the difference between theoretical energy consumption and actual energy consumption, the energy-saving potential of catalytic reformer is explored. The invention can reflect the theoretical lowest energy consumption of the catalytic reforming unit, and furthercompares the theoretical lowest energy consumption with the actual energy consumption, thereby facilitating the excavation of the energy-saving potential of the catalytic reforming unit.

Description

technical field [0001] The invention relates to the technical field of energy consumption calculation of refinery process, in particular to a refinery process energy analysis method and device. Background technique [0002] With the development of large-scale, integrated and complex petrochemical process production equipment, enterprises have also put forward higher and higher requirements for the control and optimization of the production process, especially the demand for energy-saving and emission reduction of production enterprises is increasingly valued. Advanced control strategies represented by predictive control and real-time optimization have been widely used. Advanced control technology can improve the stability rate of production equipment and achieve "card edge" optimization, so as to ensure product quality, increase productivity, reduce energy consumption, reduce accidents and avoid shutdown losses, and the economic benefits are obvious.

Problems solved by technology

In the past 30 years, the catalytic reforming technology has undergone major changes, and its operating conditions, raw material properties, product distribution, product standards, etc. have all undergone major changes. Make an accurate calculation of the energy consumption of the device

In addition, the existing benchmark energy consumption calculation method has made a series of calculation regulations during the calculation, and it is impossible to reasonably calculate the energy consumption according to the individual conditions such as the actual process level and processing plan of each device

With the emergence of various new technologies, existing energy consumption calculation methods cannot completely and accurately reflect changes in new raw materials and new processes

Therefore, it cannot reflect the minimum energy consumption that the device can theoretically achieve, which is not conducive to excavating the energy saving potential of the device
