On the morning of May 18, the construction of the fractional crystallization project for concentrated brine in the 200,000-ton/year coal-to-methanol project of Ordos Northwest Energy & Chemical Industry Co., Ltd. got underway. The project covers an area of 5,600 square meters and is located in the Western Zone of Dalu Industrial Park. The construction period is 36 months. The total investment is 150 million yuan. Once operational, the annual sales revenue is expected to reach 26.8426 million yuan, with an average annual total profit and tax of 7.2035 million yuan. The project for the quality-based crystallization of concentrated brine at Northwest Energy & Chemical is another important initiative by the company to further improve its environmental protection efforts and put into practice its corporate development philosophy of “giving priority to ecology and pursuing green development”. The project is under EPC general contracting by Shenzhen Energy Resources Comprehensive Development Co., Ltd. It has a designed treatment capacity of 40 cubic meters per hour. The process employed is the domestically developed, advanced, mature, and reliable “pre-treatment, membrane concentration, evaporation, and crystallization unit,” which enables the complete recovery of all water produced by the plant. This process facilitates the crystalline separation of industrial-grade sodium chloride and anhydrous sodium sulfate, ultimately achieving zero wastewater discharge and the resourceful utilization of salts.
