The energy consumption issue in hydrocracking

The question regarding energy consumption is too general; for devices of the same type, as their scale increases, the specific heat dissipation requirements decrease, and the costs associated with fuel and power also drop, thereby reducing the unit operating cost of such devices.

Hydrocracking technology features strong adaptability to feedstocks, high flexibility in product options, high selectivity for target products, good product quality, and high added value. It can directly convert various heavy and low-quality feedstocks into clean fuels and high-quality chemical raw materials, and has become one of the most important processes for the deep processing of heavy oils in modern refining and petrochemical industries, with increasingly widespread application both domestically and internationally. Hydrocracking technology can produce heavy naphtha products with extremely low sulfur and nitrogen contents and high aromatic potential, which can serve as high-quality feedstock for catalytic reforming units used in the production of aromatics or high-octane gasoline ； Products such as hydrocracking tail oil, light naphtha, and liquefied gas are rich in alkanes. When used as feedstock in steam cracking units for the production of ethylene, they offer advantages such as high yields of trienes, longer coking removal cycles in the cracking furnace, lower energy and material consumption, and good economic benefits. Therefore, it is highly necessary to further improve the level of hydrocracking technology for producing products intended as chemical raw materials, and to increase the output of high-quality chemical raw materials in order to meet the growing market demand.
