In the south three oil depots of the crude oil reserve and transit hub of Daqing Oilfield, two 150,000 cubic meters of crude oil storage tanks have been erected this year. According to the plan, the South 3 Oil Depot will add more than 1 million tons of stored energy by the end of 2010. By then, the crude oil reserve capacity of the Daqing Oil Field will be equivalent to the output of the oil field in the last month.
In the eastern part of Xinjiang, CNPC is building a large-scale crude oil reserve. Analysts said that PetroChina and Sinopec are currently actively deploying energy storage, especially in oil-producing areas such as Daqing and Xinjiang. These reserve bases are more focused on strategic uses.
Zhang Guobao, deputy director of the National Development and Reform Commission and director of the National Energy Administration, disclosed at the end of last year in a signed article published in the People's Daily that at the time, the first phase of the national oil reserve base had been “essentially completed†and the second phase of the base construction was being actively promoted. Will reach 26.8 million cubic meters, equivalent to 170 million barrels.
The first phase of China’s national oil reserve base started in 2003, and strategic oil reserves were built in Zhenhai, Zhoushan, Dalian, and Huangdao.
With the rapid increase in demand and the increase in imports, the issue of China's oil reserve capacity has caused the Chinese government to attach great importance and attention from all walks of life. Qu Wei, dean of the Heilongjiang Provincial Academy of Social Sciences who has long been engaged in research on oil issues, believes that in 2008 China’s crude oil reserve level was about 600 tons, equivalent to 15 days of usage, far from the equivalent of 3,600 imported 3 months imported by the International Energy Agency. Tens of tons. In the case where the country’s current production capacity is basically stable, the annual increase of about 6% of the consumption depends on imports.
Regenerated Nylon 6 is also called nylon 6 recycled material, which is generally produced by melting and granulating nylon yarn, nylon yarn or nylon cloth, because nylon 6 not only has good wear resistance, heat resistance, oil resistance and chemical resistance And processability, but also has dimensional stability and excellent mechanical properties, is widely used in automotive industry parts, gears, bearings, fan blades, pump blades, fishing gear, bicycle parts and some precision engineering accessories.
3. However, nylon 6 will degrade during processing, resulting in the loss of molecular weight, affecting the melt strength and processability of the polymer, resulting in the inability of recycled or recycled materials to be used in occasions with high performance requirements, and even possible Being treated as waste is not in line with today's theme of green and low-carbon development. Therefore, how to recycle recycled nylon 6 materials to avoid resource waste and environmental pollution has become a hot research issue in recent years.
4.cn112853534a discloses a fiber manufacturing process, especially relates to a regenerated nylon 6 fiber manufacturing process, which includes the following steps: Step 1, pulverizing nylon 6 waste; Step 2, adding catalyst and ethanol and dichloroethylene A mixed solvent of alkane; Step 3, after the dissolution, filter the undissolved solids in the solution; Step 4, cool and crystallize the nylon 6 in the filtered solution at a certain temperature into a nylon 6 solid; Step 5, place the nylon 6 solid in Drying in an oven at 100-120° C. for 3-4 hours to make the water content less than 5%; Step 6, adding additives to obtain a mixture; Step 7, melt spinning to obtain regenerated nylon 6 fibers. The invention uses nylon 6 waste to produce regenerated nylon 6 fiber, which realizes the recycling of nylon 6 waste and fully avoids resource waste and environmental pollution.
