Fubao Group Company's dimethyl ether project in 2008.

Faced with the shortage of oil, the non-renewability of energy, and the increasing demands on the environment in the world, foreign countries have already proposed the development direction of alternative fuels and clean fuels. The Chinese government has also realized the seriousness of this problem, and recently it has repeatedly emphasized to carry out this work as soon as possible. Therefore, the development of dimethyl ether has received more and more attention in recent years. Based on the development path of technological innovation and focusing on the market, the company invested 251.37 million yuan in Jiangyin Industrial Concentration Zone, Fuqing City, Fujian Province to start a 300kt/a dimethyl ether production project. The project covers an area of ​​120 acres and is constructed in two phases: The first phase invests more than 90 million yuan to build a dimethyl ether production facility with an annual output of 100,000 tons, which is expected to be completed and put into operation in August 2008; the second phase is planned to start construction in 2009 The investment budget is more than 150 million RMB. After the completion of the project, the annual sales revenue is expected to reach RMB 1.290 million.

Environmental protection implementation projects for zero discharge of wastewater from nitrogen fertilizer production in 2008:

Environmental protection is the theme of today's world development. Many countries, including China, have paid more and more attention to the sustainable development significance of environmental protection. As a key nitrogen fertilizer enterprise in Fujian Province, Fubao Group is well aware of the responsibilities and obligations of the enterprise, and has always adhered to the implementation and vigorous efforts of environmental protection management. In 2008, the company formulated the following environmental protection management projects and projects:

The treatment of urea carbon ammonium liquid and the ammonia produced in the previous section. For the treatment of this project, the urea deep hydrolysis technology is mainly used for treatment. The ammonia in the treatment process is recycled to the urea system for recycling, and the water is sent to the gas jacket or other water stations as supplementary water use. The total investment in the renovation of this project is RMB 7.5 million.

The methanol rectification residue treatment company will adopt the treatment technology of Xuzhou Water Division Research Institute, and the methanol residue will be sent to the gas generator jacket as make-up water after treatment. The total investment of the project is estimated to be 1 million yuan.

Separation of sewage treatment ensures the closed-circuit circulation of sewage in the gas generation system through the classified use of water, with a total investment of 1 million yuan.

The ice machine cooling system company will install 3-4 new evaporative cooling devices to replace some of the existing ice machine cooling systems with failures. The total investment is estimated to be 2.5 million yuan.

The terminal treatment and on-line detection system adopts biochemical treatment methods to process the closed loop discharge water of synthetic ammonia, methanol, and urea systems, and recycle or discharge them after reaching the standards. The project invests 3 million yuan.

The relocation and renovation project of the waste slag yard is aimed at the impact of the waste slag storage site in the factory on the company’s equipment damage and overall appearance. The company will build a new closed waste slag storage yard at the original slag site of the fluorination workshop to control dust pollution. The renovation project is expected to invest 3 million yuan.

The total budget for the renovation plan for the above items has reached more than 18 million RMB. After the successful renovation, the company will have the following three benefits:

Further effectively control the discharge of pollutants. Effectively control pollution and realize the closed-circuit cycle of "zero" discharge of sewage. It is estimated that the company can reduce sewage emissions by 1.154 million tons, reduce NH4-N 73.7 tons, and COD 147.8 tons every year.

There is no direct flow in the whole plant, and all the cooling water in use realizes closed circuit circulation. The total processing capacity of the existing cooling circulating water device has been greatly improved, and the cooling water recycling rate can reach more than 98.2%, and the process water recycling rate can reach 98.8%, which further reduces the consumption of synthetic ammonia production processes, saves costs and creates benefits .

Relocation of the original slag field effectively eliminates dust pollution, improves and optimizes our working and living environment, promotes clean production and circular economy, and also realizes the sustainable and healthy development of the enterprise.
