Abstract:

Research on the transformation and development plan of increasing production of chemical feedstocks for example enterprises. The influences of ebullated-bed hydrocracking, slurry bed hydrocracking and flexi-coking for heavy oil processing on the enterprise are analyzed from the aspects of economic benefit, CO₂ emission and carbon tax. The results show that the economic benefit is the best when the flexi-coking scheme is selected for heavy oil processing, but its CO₂ emission is high, and the economic benefit is still the best after considering a certain carbon tax is levied; Flexi-coking technology is conducive to solving the fuel balance problem of the whole plant and can bring good economic benefits. However, in areas with limited CO₂ emission quota, ebullated-bed hydrocracking scheme should be given priority. This scheme has good economic benefits and small CO₂ emission, and can also take into account the production of low sulfur marine fuel oil; When hydrocracking technology is adopted for heavy oil processing, it has high conversion rate, high yield, high-quality ethylene cracking feedstocks and low CO₂ emission. With the development of green energy, the cost of green hydrogen is gradually reduced, and the advantages of hydrogenation route will be more prominent.
