This base is developed in three stages: short term, middle term and long term according to its planning. The short-term stage is in 2015-2020. In this stage, 16km of lands will be developed and the project to promote the integration of oil refining, ethylene and arene will be carried out to primarily build it into a production base of petrochemical materials. In the middle stage, 10km of lands will be developed. The second large-scale refining-chemical integration project will be promoted and arene as well as project of fine chemicals in middle and lower streams will be developed at the same time. By 2025, the production capacity of oil refining is expected to reach 40,000,000tons per year. In long-term stage, it is expected to form a world-level large-scale, comprehensive and modernized petrochemical industrial base.
