On July 17-19, CNCEC ECEC held the 90% model review meeting of 3*1000kt/a Sulfuric Acid Plant Project for 67000 TPA Nickel Equivalent Hydrometallurgical Project of PT.FAJAR METAL INDUSTRY. The design team made an introduction of the main process flow and pipeline layout for the sulfuric acid production plant, and deeply discussed the suggestions put forward by the project management team, to further optimize the design scheme. The review meeting was not only a verification for the designing feasibility, but also a commitment to safety and quality. It ensures that the plant can meet the efficiency and safety standards in the future, and lays a solid foundation for the smooth construction and stable operation of the project.
