Fluidized bed technology

Compared with the fixed-bed hydrogenation process using low-quality heavy oil, U.S. technology features a wider range of suitable feedstocks, higher reaction conversion rates, higher space velocity, a lower hydrogen-to-oil ratio, lower energy consumption, easier scale-up of the equipment, simpler operation, and lower investment costs. It simultaneously enables the online removal and replenishment of the catalyst, ensuring the long-term safe operation of the process unit. All technical parameters of the operational industrial-scale unit exceed expectations: desulfurization rate > 85%, denitrification rate > 80%, conversion rate of resins and asphaltenes > 90%, and yield of liquid products ≮ 94% (based on 100% full-range feedstock); no low-value-added products (asphalt or coke) are produced.

#Here’s a quick response: Projects that utilize EUU technology see significant reductions in overall investment costs and operational expenses, while at the same time minimizing the negative environmental impact of processing low-quality heavy oil. This helps to improve both the economic and social benefits for enterprises.

From August 15 to 18, 2016, the China Petroleum and Chemical Industry Federation organized well-known experts in the industry to visit the site in Hebei’s Xin Qiyuan to evaluate the 100,000 tons per year boiling-bed hydrogenation unit designed by Xinyou Energy. After 72 hours of on-site testing and calibration, the experts gave high praise and recognition to Xinyou Energy’s \"Boiling-bed Upgrading Technology for Low-quality Heavy Oil (abbreviated as EUU)\“. On September 11, 2016, the EUU technology successfully passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation in Beijing. The evaluation committee deemed that this technology features advanced processes and high innovation levels, and is overall at an international advanced stage; it unanimously agreed that the boiling bed hydrogenation technology for low-quality heavy oil passed this evaluation.
