On October 11, 2007, another new project of Beijing Fine Chemicals Base, a new type of diesel engine exhaust gas eliminating agent developed by Beijing Chemical Reagent Research Institute - high-purity urea solution was tendered for a new type of diesel engine exhaust gas elimination agent organized by Beijing Public Transport Corporation. Winning the bid at the conference. This indicates that the Beijing Fine Chemicals Base has made another contribution to the Beijing Olympics, and that all emissions from the Beijing bus diesel engine before the Olympic Games will reach the Euro IV will become a reality, and will promote Beijing's diesel engine exhaust emissions to a high standard.
In addition, the base also revolves around a series of environmental protection projects for the Olympic Games, such as the recycling and recycling of used tires, the 100Kt/year biodiesel project of Beijing Gushan Bioenergy Co., Ltd., and Beijing Chemicals Recycling Co., Ltd. The center has 7,000 tons/year of waste chemical reagents, solvent recovery projects, and energy-saving lamp projects for Beijing Chemical Industry Plant.
It can be said that at present, the base will become an indispensable part of the Beijing circular economy industrial chain. After more than four years of planning and development, the base has formed a modern fine chemical industrial chain of electronic chemicals, photosensitive chemicals, new materials, chemical reagents and plastic additives.
The fine chemical industry base is currently focusing on the development of environment-friendly projects with high correlation, long industry chain, high technological content, and high added value, in line with the requirements of “fine, serialized, specialized, functional, and high-efficiencyâ€. Based on the needs of sustainable development of urban industries, the base will be built to become China's largest fine chemical industry base integrating scientific research, development, production and services.
New Materials Application and Demonstration National Fine Chemical Industry Base has established a recycling center for waste tires, which specifically “eats†used tires in Beijing and other places, and turns used tires into “harm to harm and waste into treasureâ€.
Beijing’s vehicle ownership accounts for 1/10 of the country’s total. There are more than 10 million waste tires produced each year, and it grows at a double-digit rate each year. By 2008, the annual output of used tires in Beijing will reach more than 12 million. Article. Because waste rubber is a thermosetting polymer material, it is difficult to degrade under natural conditions, and it will not rot or deteriorate if abandoned on the surface or buried underground for a hundred years. The accumulation of waste rubber takes up land and pollutes the environment. It has become a major public health hazard, and it has become increasingly serious. It is known as black pollution.
This center handles 15,000 tons of tire tire normal temperature additive fine powder production line and its supporting facilities. It covers a total area of ​​45 acres and a total construction area of ​​6,670 square meters, of which the collection and distribution center covers an area of ​​30 acres and a building area of ​​1,670 square meters. m; new production base covers an area of ​​15 acres, construction area of ​​5,000 square meters, can produce 80 to 120 mesh fine powder 10,000 tons per year, to achieve sales of more than 50 million yuan.
Rubber powder, as a resource recycling material integrating green environmental protection and asphalt modifier, has been widely used and applied in developed countries since the 1980s. The use of modified asphalt mixture with rubber powder as a modifier, compared with traditional asphalt pavement, can not only prolong the life of the highway, reduce the maintenance cost, but also improve the driving safety of the automobile; it can be reduced compared with SBS modified asphalt. The road noise of 3-6db means that the road noise is reduced by 50% to 60%, which is equivalent to reducing the traffic flow by half, and the construction cost is reduced by as much as 30%. In the United States, Canada, Europe and other countries and regions, rubber powder is commonly used as a material for modified asphalt. In China, application research in this field has also begun. Rubber powder modified asphalt has good effect, low cost and integrates environmental protection and comprehensive utilization of resources.
In addition, fine rubber powder can not only partially replace natural rubber or synthetic rubber, saving resources, reducing costs, but also in terms of wear resistance and other technical indicators have improved. On the one hand, it alleviated the situation of severe shortage of natural rubber; on the other hand, the waste rubber was recycled and reused, and the problem of waste rubber polluting the environment was solved. Rubber powder can not only be used in road asphalt and rubber fields, but also widely used in automotive rubber parts and tire production, as well as sound insulation and waterproof coatings, building materials, new decorative materials, rubber and plastic blend materials, etc. Products.
According to the "Beijing Olympic Action Plan," Beijing invested 90 billion yuan in the construction of transportation infrastructure. Newly built or rebuilt roads and highways for more than 900 kilometers, according to 15% of 900 kilometers, the demand for rubber powder in Beijing will reach 20,250 tons. There is no doubt that the construction of the Beijing Olympic Green-friendly road will play a huge role in demonstrating and promoting the low-cost development of high-quality rubber powder modified asphalt in China.
Use of Chemical Waste to Make the Most of Its Use Currently, there are a large number of hazardous chemical wastes such as organic solvents and chemical reagents in Beijing. The main sources are the electronics industry, research institutes and universities. To this end, the Fine Chemical Industry Base has also gone to the Beijing Chemical Industry Recycling Center, Beijing Huateng Industrial Group Corporation, to waste 7,000 tons of waste chemical reagents and solvent recovery projects. In Beijing, these organic solvents and chemical reagents were mainly burned. Although this method can eliminate pollution, it has not yet been implemented to "make the best use of it." Many things that can be recycled are burned in vain, and there are hidden dangers of fire and explosion.
The project uses advanced chemical devices and processes to separate chemical solvent wastes and recover many organic solvents. The waste chemical reagents are analyzed and confirmed as components and further purified to form new products and return to the market. The recovered products can meet the national or industry product quality standards, and can also be made into different grades of products according to the needs of users. This is generally impossible for devices with simple processes and small scale.
The recovered chemical solvents and reagents have a wide market prospect and are indispensable basic raw materials for fine chemicals, daily-use chemicals, paint and coating industries, electronic chemicals, and pharmaceutical preparations. The use of waste chemical solvents and reagents in the industrial ecological closed loop recycling system can greatly reduce the resulting environmental pollution and waste of resources, fully embodying the concept of circular economy.
The main products recovered after recycling include: organic solvents such as isopropanol, acetone, ethyl acetate, and toluene, as well as various chemical reagents. The principle of recycling waste chemical solvents and reagents is "a high starting point, high technology, leaving no future problems for the benefit of Beijing." The project has reliable technology and reasonable design. There is no new pollution factor, which reflects the clean production process and realizes the unity of economic, social and environmental benefits.
Renewable energy industry has achieved new breakthroughs Another project in the base is Beijing Gushan Bio-Electric Co., Ltd.'s 100,000-ton/year biodiesel project. The project uses waste vegetable oil and methanol as raw materials to achieve alcoholysis and esterification in a one-step process under the action of slightly acidic catalysts. It requires less water washing than domestic two-step production, reduces water pollution, and has a simple process flow. The production cost is low, and the conversion rate is 95%, making the production of biodiesel from waste vegetable oil a reality. Its production process is the first in the country.
Beijing has more than 2.3 million vehicles, and the consumption of vehicle diesel has reached 81,000 tons/year. The biodiesel production of this project is 100,000 tons/year, accounting for only 1.3% of Beijing's total diesel demand. Can ease the tension in Beijing's diesel demand.
In addition, based on the environmental pollution and greenhouse effect caused by petrochemical fuels, alternative fuels such as compressed natural gas (CNG), liquefied natural gas (LNG), liquefied petroleum gas (LPG), methanol, and ethanol have emerged. However, these alternative fuel system investments have occurred. Huge costs such as refueling equipment, storage equipment, and engine rebuilding are very high, so there is no universal promotion. The biodiesel as a substitute, the overall emissions of pollutants decreased by 70% compared with petrochemical diesel; black smoke components decreased by 80%; fine particles reduced by 30%; sulfur oxides by 95%; carbon monoxide by 53%; hydrocarbons by 95%; carcinogenicity Aromatic hydrocarbons are reduced by 95%. Therefore, biodiesel is the most ideal substitute for petroleum energy developed by countries around the world. Its use performance is very similar to petrochemical diesel, and it is a renewable clean energy source. At present, the biodiesel industry has received the support of the relevant state departments and has been included in the national plan.
Gushan Company digested and absorbed foreign advanced technology, designed an advanced biodiesel distillation separation device, extracted oil acid from the waste oil of rapeseed oil, distillation refining high-quality biodiesel. It is a clean renewable energy source, a substitute for petroleum diesel, has excellent environmental protection characteristics, good low temperature engine starting performance, good lubricity, excellent combustion performance and renewable performance. China's rapeseed production is second only to the European Community, ranking second in global rapeseed production and producing more than 15 million tons of vegetable oil annually. According to 2005 consumption of 20.6 million tons of edible oil, edible oils and leftovers produced from edible oil can be used to produce more than 5 million tons of biodiesel.
Beijing Chemical Plant's three-phase energy-saving lamp powder project with a total investment of 16 million yuan in three phases will last for two years and will reach an annual output of 800 tons to 1,000 tons in 2009. At present, the 80-ton production line in the first phase of the project has been completed and has passed the acceptance of the Beijing Fire Bureau and the Safety and Technical Supervision Bureau.
In addition, the base also revolves around a series of environmental protection projects for the Olympic Games, such as the recycling and recycling of used tires, the 100Kt/year biodiesel project of Beijing Gushan Bioenergy Co., Ltd., and Beijing Chemicals Recycling Co., Ltd.
