Site

In the petrochemical sector, Hengli (Dalian Changxing Island) Industrial Park is one of the largest and most advanced PTA production bases with an annual production capacity of up to 12 million tons. The project was completed and put into operation with high standard, strict requirements and at a fast pace, which has set several records in the industry internationally.

• Axen's model of the site:
  
  The Hengli project in China is an exemple of the option that integrates upgrading heavy oil at the refinery with a petrochemical plant downstream. The configuration includes the high-conversion H-Oil suite of technologie; the H-Oil process, SDA (Solvahl), and hydrocracking (HyK) of vacuum gas oil (VGO) and DAO for the maximum yield of naphtha for processing in a downstream petrochemical plant. This 110000 b/d plant uses two parallel trains with two ebullated bed reactors in series for each train. The design feedstock is a blend of Arabian and Marlin crudes. Pitch from the SDA unit is routed to a gasification unit. Axens provided the major  technologies for both the refining and petrochemical plants. This unit is scheduled to start-up in the first semester of 2019. More than 92 wt% conversion will be achieved with no production of fuel oil. (Feb 2019, Source)
