During the “12th Five-Year Plan” period, the petrochemical federation will cooperate with the Ministry of Industry and Information Technology and focus on the promotion of domestic spacecraft technology with independent intellectual property rights, multi-nozzle coal-water slurry gasification technology and Qinghua furnace technology, and energy conservation and consumption reduction in the coal chemical industry. China plays an active role. The reporter learned that these technologies have been listed in the "Advanced Coal Gasification Energy-saving Technology Promotion and Implementation Plan" recently released by the Ministry of Industry and Information Technology.

Sun Weishan, deputy secretary-general of the China Petroleum and Chemical Industry Federation, said that at present, most of the coal chemical industries such as ammonia synthesis and methanol production in China use intermittent fixed-bed coal gasification technologies, which require strict raw materials, high energy consumption, and serious pollution. Advanced coal gasification technology mainly refers to pressurized coal gasification technology and new coal-water slurry gasification technology. It has outstanding advantages in terms of energy conservation and environmental protection, and adaptability of coal types. It can achieve clean and efficient use of coal and reduce production costs. And is conducive to the development of downstream products.

It is understood that the coal gasification process is the most energy-intensive process for ammonia and other coal chemical industries. For example, the energy consumption of synthetic ammonia gasification accounts for more than 60% of the energy consumption of the entire process. Compared with the traditional coal gasification process, under the same coal raw materials, advanced coal gasification technology can reduce the energy consumption of synthetic ammonia tons by an average of 0.22 tons of standard coal.

According to the “Advanced Coal Gasification and Energy Saving Technology Promotion and Implementation Plan” released by the Ministry of Industry and Information Technology on March 16, during the “Twelfth Five-Year Plan” period, Yangmei Coal Group Taihua, Sichuan Coal Gasification Co., Ltd., Henan Jinkai Investment Holding Group will be selected. Nineteen large and medium-sized coal chemical enterprises have undergone technological transformation and strive to replace 7.8 million tons of atmospheric fixed-bed coal gasification capacity, achieving annual savings of 1.71 million tons of standard coal.

According to the introduction of the Petrochemical Federation, China's own spacecraft technology with independent intellectual property rights, multi-nozzle coal-water slurry gasification technology, and Qinghua furnace technology have already built some industrialized installations and have the conditions for comprehensive promotion. For example, the multi-nozzle coal-water slurry gasification technology has been put into operation in 15 gasifiers of 7 companies including Shenhuaning Coal, Jiangsu Thorpe, Ningbo Wanhua and Anhui Huayi; 22 aerospace furnace technologies have been used by more than 10 companies. Gasifiers were put into operation or under construction; Tsinghua furnace technology was successfully applied in Shanxi Fengxi Fertilizer Industry (Group) Co., Ltd., and 14 gasification furnaces were under construction in 6 companies.

However, advanced coal gasification technology still has some difficulties in large-scale promotion. It is mainly the transformation that requires large capital investment, and the enterprises need a process for understanding the advanced coal gasification technology.

The relevant person in charge of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology stated that in order to ensure the promotion of advanced coal gasification technology, the state will adopt four measures: increase the support for energy-saving technological transformation of enterprises, and improve diversified investment and financing mechanisms for energy-saving technological transformation of enterprises; Strengthen the supervision and management of technological upgrading projects of advanced coal gasification technology; improve the technical evaluation standards and application specifications.

Inflatable Baby Pool

Swimming is good for babies' health. Many mothers take their babies to the public swimming pool to swim in the public swimming pool, so they buy Inflatable Swimming Pools at home. This is a very good choice.

The inflatable baby pool has the following advantages
1. The baby's home inflatable swimming pool can not only open the inflatable and use it, it can be folded and folded. It is convenient to store and save space.
2. The price of inflatable swimming pools on the market is not too expensive, and ordinary families can afford it. Therefore
3. Most of the plastic materials, high density and not easy to damage. As long as you do well in maintenance, the service life is more than 1 year;
4. The scope of application is wide and easy to use at home. It can also be used outdoors. If you have the habit of going out to play, you may wish to buy one to prepare from time to time.
