It is understood that in order to fully complete the "Eleventh Five-Year" energy-saving emission reduction targets, this time the first to start the energy efficiency of the four targets of the standard activities, involving a total of crude steel, electrolytic aluminum, ammonia, caustic soda, calcium carbide, etc. 13 kinds of products (Process), using the advanced level of energy efficiency of similar domestic companies as a reference value, implementing energy efficiency standards for compliance targets. The index of energy efficiency of synthetic ammonia, an indicator of caustic soda energy efficiency, and benchmark of calcium carbide energy efficiency, which use anthracite as raw materials, will serve as reference standards for the chemical industry to carry out energy efficiency standards for standard target activities.
The comprehensive energy consumption of high-quality anthracite lump coal, comprehensive energy consumption of coal briquettes, raw coal consumption (high-quality anthracite lump coal), and raw coal consumption (brick coal) are 1420, 1650, and 1180, respectively. 1410 kg standard coal/ton; the energy efficiency benchmarking index of caustic soda products in the chlor-alkali industry is regulated by the ion-exchange membrane method and the diaphragm method from the following aspects: liquid caustic soda, solid caustic soda, electricity consumption and steam consumption; There are two types of energy consumption indicators and recovery indicators, of which the comprehensive energy consumption in the energy consumption index is 1,000 kg standard coal/ton, and the recovery rate of tail gas in the recovery index is 100%.
Zhang Juntong, a consultant of the China Chemical Industry Energy Technology Association, told the National Development and Reform Commission that as early as November 2007, it began to implement energy efficiency benchmarks in key energy-consuming industries such as chemical, steel, and cement, and chemical companies selected Yuhua Aerospace Chemical Company, Shandong. Hengtong Chemical Company, Hebei Shenghua Chemical Company 3 caustic soda companies as pilot units. Pilot work has achieved remarkable results and the technology has reached the domestic advanced level. "This energy efficiency benchmarking campaign is an extension and extension based on previous pilots," Zhang said.
Zhang Juntong believes that the development of energy efficiency on the standard energy analysis to grasp the level of energy management and energy use of enterprises, identify the existence of energy use problems, find out the weak links, identify energy-saving direction and energy-saving potential, determine the adoption of energy-saving technologies and management measures . At the same time, energy efficiency benchmarking activities have significant implications for achieving the “Eleventh Five-Year†energy-saving goals.
According to Sun Weishan, secretary-general of China Calcium Carbide Industry Association, 413 companies in the calcium carbide industry participated in the event.
The Notice of the Ministry of Industry and Information Technology of the People's Republic of China on Launching Energy Efficiency Standards for Key Energy Use Industry to Mark Target Activities has been proposed to take the lead in conducting energy efficiency benchmarking activities in four key energy-using industries such as chemicals, steel, non-ferrous metals and building materials. This has caused widespread concern in the chemical industry in recent days. Industry-related experts agree that energy efficiency benchmarking will lead to “comparison, learning, catching up, and surpassing†among companies in the industry, thereby improving the energy efficiency of enterprises, reducing energy consumption and production costs.
