According to the official of the National Energy Administration at the fifth meeting of the 17th Central Committee of the Communist Party of China, according to the plan, the energy consumption per unit of GDP during the "Twelfth Five-Year Plan" period will fall by 17.3%. 17.3%. It can be seen that this binding indicator has been determined to be normalized. In the new five-year planning period, energy conservation and consumption reduction and a low-carbon economy will undoubtedly remain an industry threshold. At present, as far as the domestic chemical industry is still operating extensively, in order to meet new challenges, a low-carbon economy should be vigorously promoted, and this concept should be applied to all aspects of the enterprise.
Chemical companies have a close relationship with carbon reduction. Every day, chemical companies deal with fossil resources such as petroleum, coal, and natural gas, or use them as raw materials or power. Chemical companies are best equipped to be an outstanding low-carbon economic practitioner.
First of all, the selection of advanced process equipment is a shortcut to energy conservation and carbon reduction. Scientific and technological progress is implemented in the industrial category, which is mainly reflected in the more sophisticated production technology and equipment, which is more conducive to energy saving and emission reduction; and the specific product reflects high quality, high efficiency, and low consumption, which is the best way to make the most of everything. For example, the current domestic caustic soda industry consumes about 2,500 kWh of electricity per ton of diaphragm alkali, and about 2,300 kWh of electricity per ton of ordinary ion-membrane alkali, while the current consumption of the most advanced “zero-pole-pitch” ion-membrane alkali ton consumes only 2088 kWh. It is reported that the current scale of caustic soda in China is close to 28 million tons, but there is still about 26% of the production capacity of diaphragm alkali, which alone has a large space for low carbon.
Secondly, existing process upgrades and process optimizations are effective ways to save energy and reduce carbon. Chemical production has the characteristics of complex processes, and if the optimal optimization of various process parameters is achieved, it means reduced emissions and improved energy efficiency. For example, the production of yellow phosphorus is a typical large energy consumer, and the electricity consumption per ton of phosphorus is about 15,000 kWh. However, if in the production process, by continuously optimizing the proportion of phosphate ore, silica, coke and other ingredients, and optimizing the electrode position, and at the same time supplemented by microcomputer control in key processes, strictly control each process parameter to stabilize the furnace ore, on the one hand can The power consumption per ton is reduced to 14,000 kWh, which greatly reduces the manufacturing cost; on the other hand, by increasing the yield, the phosphorus content in the phosphorus slag and phosphorus sludge is reduced, which is conducive to environmental protection.
As the "Twelfth Five-Year Plan" approaches, the opportunities for survival and development will only be left to those enterprises that plan ahead. Prosperity practitioners prosper and inaction retrogrades perish. Whoever has the secrets of energy saving and low carbon can win sustainable and healthy development.
