The Organic Solvent Refining Project in Meishan, Sichuan
The organic solvent refining project in Meishan city of Sichuan province, which is planned to invest 800 million yuan in two phases. This project is a matching item of the 8.6th generation TFT-LCD project of Chengdu Zhongdian panda.
The factory site is located in petrochemical Avenue, Chengmei Petrochemical Park, Meishan City, Sichuan Province, with a total net floor area of 63.56 mu in phase I and 60 mu in phase II.
This project is expected to be completed and put into operation in December 2018. The project cooperates with Japan Ruihuan, a leading enterprise in the hazardous waste industry, so as to recover and regenerate the 2 big-categories and 5 small-categories of hazardous waste involved in the national hazardous waste list (2016) by the distillation process.
After the completion of the final phase of the project, we can regenerate 60,000 tons of organic solvents and refine and recover 50,400 tons of various solvents every year.
As an annual major investment attraction project of Sichuan Province in 2016, Chengdu 8.6th generation LCD panel production line of China Electronics will be officially started in Southwest Airport Economic Development Zone, Shuangliu District, Chengdu, and it will be jointly constructed by East China Science & technology of China Electronics panda and Chengdu government.
The total investment of the project is planned to be 28 billion yuan, covering an area of about 1021 mu, with a total construction area of nearly 700,000 ㎡. And the construction content covers array, CF, LCD / SC, LCM production line, purification plant, supporting power equipment and R & D facilities.
The waste liquid produced by the use of these organic solvents can replace the imported products after refining. Moreover their relative price is low, the added value of the products is high, the market prospect is wide, and they can produce greater economic benefits and environmental protection benefits for society and companies.
In the late years, a large number of IT electronic products enterprises, LCD panel manufacturers, pharmaceutical and chemical enterprises and lithium battery manufacturers have settled in Chengdu and Meishan, which has promoted the economic rapid development of Sichuan Province.Chengdu, Meishan and their surrounding areas have become one of the important bases for IT electronic products and lithium battery production in China. IT electronic products industry, liquid crystal panel production, pharmaceutical and chemical industry and lithium battery production enterprises will produce a large number of organic solution waste liquid in the production process. If these wastes are not properly treated, the normal production of upstream enterprises will be affected, and the surrounding environment will be polluted. And if the method is improper, it will cause secondary pollution, so the market potential of regeneration and refining of organic solvent waste liquid is very huge.
Though the production of waste organic solvents in the enterprises of Chengmei Park and its surrounding areas, the production of waste-organic solvents in the enterprises of Chengdu and its surrounding areas is about 100,000 tons per year.And in the context of rapid development of the local economy, the number and production capacity of relevant enterprises will continue to increase, so the production of waste organic solvents will also continue to increase. Therefore, we expect that the production of waste organic solvents will exceed 150,000 tons / year in 2020.
The project includes the recovery and treatment of all kinds of solvent recovery and treatment, such as SP-06 stripping liquid waste, No.9500 cleaning agent waste, CST-9300 diluent waste, EBR diluent waste, LT360 stripping liquid waste, cleaning agent waste, LCD cleaning liquid waste, DIBK, MIBK mixed waste, DMAC mixed waste, T acetonitrile mixed waste, 2ME-T acetonitrile waste, NMP waste, DMF, NMF mixed waste, DCP waste, tetrachloroethylene waste, acetonitrile waste, DMC waste, toluene mixed waste liquid, etc.
The project will adopt the advanced rectification process owned by the investor to deal with the waste organic solvent. And the recovery is over 80%. Moreover, the product has the high quality of electronic grade, which can be reused in the original enterprises. And the product market is guaranteed.
Beyond that, we can use the refining technology to recover the waste organic solvent production process, and make full use of the uncomplicated characteristics of the impurities contained in each waste organic solvent and use flash evaporation and distillation technology to refine the waste organic solvent, making it a high-purity organic solvent, so as to achieve the common development of resource reuse and economic benefits, social benefits and environmental benefits.
