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

Abstract

The invention provides a method and device for analyzing the energy consumption of diesel hydrogenation. The method includes: according to the calibrated benchmark working condition data and process data, the actual energy model of the diesel hydrogenation device is established and the actual energy consumption of the diesel hydrogenation device is calculated. Approval; do not change the existing process flow, according to the calibrated processing capacity and product yield, in the case of meeting the preset quality requirements of the product, by adopting the optimized process and equipment operation data, determine the achievable performance of the diesel hydrogenation unit The operating conditions of the lowest energy consumption, carry out relevant calculation regulations, establish the theoretical energy model of the diesel hydrogenation unit and simulate the theoretical energy consumption of the diesel hydrogenation unit; tap the energy saving of the diesel hydrogenation unit by comparing the difference between the actual energy consumption and the theoretical energy consumption potential. The present invention can firstly obtain the theoretically attainable minimum energy consumption of the diesel hydrogenation unit, and then compare the theoretically attainable minimum energy consumption with the actual energy consumption, thereby helping to tap the energy-saving potential of the diesel hydrogenation unit.

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...
