1.1.1 Energy is an important material basis for my country's socialist modernization drive. Now and in the future, the ministry must implement the policy of giving equal importance to development and conservation of energy. 1.1.2. These regulations apply to the design of new construction, reconstruction and expansion projects of large-scale synthetic equipment. 1.1.3 The comprehensive energy consumption level is divided into the first-level energy consumption standard, the second-level energy consumption index and the third-level energy consumption index. New projects should try to reach the first-level energy consumption index, which should not be higher than the second-level energy consumption index. Reconstruction projects should try to reach the second-level energy consumption index. Expansion projects should reach the second-level energy consumption index, which should not be higher than the third-level energy consumption index. 1.1.4 New energy-saving processes, technologies and high-efficiency equipment should be adopted. Outdated processes with high energy consumption and electromechanical products and equipment that have been announced to be eliminated by the state should not be adopted. 1.5 Attention should be paid to the selection of energy types, reasonable use of energy, comprehensive utilization of process heat energy, multi-level utilization of high-level heat energy, reasonable use of waste heat, waste pressure, condensate, etc., to improve the overall thermal efficiency. 1.1.6 Energy consumption detection and control instruments should be set up in the design, and the level of automatic control should be continuously improved. 1.1.7 Strive to improve investment efficiency and shorten investment payback period 1.1.7.1 The investment of newly built large-scale synthetic nitrogen plants shall be calculated according to the static payback period, which shall generally not exceed five years. 1.1.7.2 The reconstruction project shall save 41.888×10 coke (19 million kcal) per month, and the investment shall be less than 1,000 yuan. 1.1.7.3 When large-scale synthetic ammonia plants using oil as raw material and fuel are converted to coal instead of oil, the investment shall be less than 50 yuan per year to replace one ton of oil (including light oil, diesel, and heavy oil). 1.1.8 The feasibility study report and preliminary design of new and large-scale technical transformation projects shall add chapters on energy conservation and rational utilization. 1.1.9 In addition to the implementation of these regulations, energy-saving design shall also comply with relevant regulations and specifications issued by the state. 1.2 Comprehensive energy consumption indicators 1.2.! The three-level indicators of comprehensive energy consumption for energy-saving design of synthetic nitrogen production with different raw materials formulated in this regulation are shown in Table 1, 2-1.1.2.2 During the "Seventh Five-Year Plan" period, new plants using natural gas or light oil as raw materials should not exceed the second-level indicators, and rebuilt plants and expanded plants should try to reach the second-level indicators. 1.2.3 New plants using heavy oil and coal as raw materials should not exceed the second-level indicators. On the basis of the existing technological level, new plants designed in the late 1990s should further make full use of energy to achieve the first-level indicators of this regulation. 1.2.4 Continuously adopt new processes and technologies. New plants designed in the 1990s using natural gas and light oil as raw materials should meet the first-level indicators of this regulation. 1.3 Energy consumption indicators of main processes

Combined utilization, total power consumption is extremely small (some factories are self-sufficient in electricity), the energy utilization of the entire factory is very complex. When different process flows are adopted, the consumption of each section is not interlaced, and it is not convenient to list the comprehensive energy consumption indicators by section. Therefore, the following window lists the energy consumption indicators of raw materials, fuel, water, electricity, and steam in each process of our factory's current production process. 1.3.1 Comprehensive utilization of natural gas as raw material Energy index of main process of nitrogen forming device () Raw material consumption (in tons):
