Issue 34/2013 - Liquid phase cycle hydrogenation technology passed qualification

Recently, the liquid phase cycle hydrogenation (SRH) technology jointly undertaken by Sinopec Luoyang Engineering Co.
, Ltd.
, Sinopec Fushun Petrochemical Research Institute, Changling Refining, Jiujiang Petrochemical and Zhanjiang Dongxing Petrochemical Co.
, Ltd.
passed the expert appraisal
organized by the Ministry of Science and Technology Development of Sinopec.
The appraisal committee believes that the technology has reached the international advanced level, and the existing technology can be further promoted and applied, and it is recommended to carry out V.
product tests
in high-sulfur diesel producing countries.

Compared with conventional hydrorefining, this technology does not set up a hydrogen circulation system, and has the advantages of
small reaction temperature rise, less cracking reaction, high catalyst utilization rate, and less heat loss.
Compared with the drip bed diesel hydrorefining plant of the same scale and target product, the equipment investment can be saved by more than 20%, and the operating energy consumption can be reduced by more than
20%.
The project has applied for 30 invention patents
.

The technology has been industrially tested in Changling Branch, and has been industrially applied in 1.
5 million tons/year of Jiujiang Branch and 2 million tons/year diesel liquid phase cycle hydrogenation unit of Zhanjiang Dongxing Petrochemical Co.
, Ltd.
, both of which meet the requirements of
key research indicators.
