Shenghong Refining & Chemical (Lianyungang) Co., Ltd has selected Axens’ ebullated-bed residue hydrocracking technology, H-Oil®, for a 3.2 million tpy capacity unit combined with a 3.45 million tpy distillates hydrocracking unit using HyK technology. These will be the key units for residue valorisation at its petrochemical complex in Lianyungang, Jiangsu, China.

The project aims to increase the naphtha production capacity by 3.6 million tpy in single train units. Beyond vacuum residue, the Axens’ solution will handle steam cracker py-oil as feed to the H-Oil unit and effluents of existing coker to the HyK unit.

The solution proposed by Axens features the following units:

  • H-Oil (ebullated-bed residue hydrocracking) technology originally developed by Axens. The H-Oil will apply supported catalysts from Shell Catalysts & Technologies in conjunction with HTI’s HCAT technology to maximise performances. The high quality unconverted residue will feed the existing coker unit.
  • Maxi naphtha Distillate HyK (hydrocracking) technology originally developed by Axens and applying advanced catalytic solution in combination with high efficiency heat integration thanks to ZPJE spiraled tube heat exchangers technology.

“The routing optimization between the distillate hydrocracking HyK unit and the H-Oil unit allows delivering superior naphtha yields and improving coker’s feed quality. This project demonstrates superior and energy efficient technology solutions offered by Axens to support those highly integrated refinery- petrochemical complexes”, said Jacques Rault, Middle Distillates & Conversion Business Line Director.

Since 2014, the Axens’ ebullated-bed residue hydrocracking H-Oil technology has been adopted by several Chinese refineries – public as well as private – demonstrating the its ability to cope with several refining environments in an energy efficient and cost effective manner.

This brand new state-of-the-art residue hydrocracking unit will allow Shenghong to further improve their economic resilience and competitiveness while producing highly valuable petrochemical prone feeds.

Axens will also supply HyK catalysts, equipment and full services offer from personnel training to plant start-up.
