By comparing the actual energy consumption with the theoretical energy consumption, the energy-saving potential of the diesel hydrogenation unit is explored. At first, that invention can obtain the low energy consumption that the diesel oil hydrogenation device can theoretically achieve, and then compares the low energy consumption that the diesel oil hydrogenation device can theoretically achieve with the actual energy consumption, thereby facilitating to tap the energy-saving potential of the diesel oil hydrogenation device.

Description

technical field [0001] The invention relates to the technical field of refinery process energy consumption calculation, in particular to an energy analysis method and device for diesel hydrogenation. Background technique [0002] With the increasingly stringent environmental regulations and the enhancement of people's awareness of environmental protection, countries around the world have increasingly stringent requirements on the quality of diesel for vehicles. Refining companies are paying more and more attention to energy saving and consumption reduction in order to reduce product costs and improve their own competitiveness. The demand for ultra-low-sulfur clean diesel in the hydrogenation reaction market is also increasing with the acceleration of diesel quality upgrading, especially the national implementation of the National V standard for vehicle diesel, and diesel quality upgrading is imminent. Under the background that the continuous expansion of refineries cannot s...

AI Technical Summary

Problems solved by technology

[0004] Existing calculation methods for diesel hydrogenation energy consumption all use empirical correlation or statistical methods, which cannot make accurate calculations for the energy consumption of diesel hydrogenation units

In addition, it is impossible to reasonably calculate energy consumption based on individual conditions such as the actual process level and processing plan of each device; it cannot fully 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
