4 Energy-saving technical measures for main processes
4.1 Energy-saving technical measures for main processes of ammonia-soda method4.1.1 The alkali process improves the reverse evaporation process flow and process conditions, such as using mother liquor and dilute liquor to separate the steam pan, recovering flash heat from mother liquor steam, and using efficient heat exchangers. 4.1.2 Improve the absorption process flow of the alkali process and use efficient coolers. 4,1.3 The high-temperature cooling water discharged from the burning and steaming process is used for clothing, heat, and the lime process uses this cooling water to recover the heat of the effective air of the ash machine, which can increase the temperature of the ash water and increase the concentration and temperature of the ash milk. 4.1.4 The carbon dioxide compressor can be double-acting with a steam turbine, and the exhaust steam can be reused. 4.2 Energy-saving technology of alkali washing method: The use of external cooler in the ammonium hydride process can replace the refrigerant in the steam turbine. 4.3 Thermal system and equipment can achieve multiple energy-saving benefits. 4.3.1 In the design of soda ash plants using the alkali recovery method or the alkali treatment method, no matter the size, it is recommended to carry out steam balance for the whole plant to reduce the energy consumption per unit product. According to the type and size of the soda ash plant, the steam system of the steam exchange point and the steam storage and engine power room should be optimized to achieve steam balance for the whole plant. 4.3.2 The steam system design can be based on the "Design Regulations for Steam Systems in Chemical Enterprises (Trial)" (TC108A2-83) compiled by the Thermal Engineering and Design Center. 4.3.3 The steam system inside the soda ash production plant can be reused multiple times and can be based on the following principles: (1) The superheated air steam drives the carbon dioxide compressor, and the extracted high-pressure steam is used to spray the mother liquor into the black tower. The waste liquid steam can be used to return to the mother liquor or the desulfurization tower. (2) The superheated steam (after cooling and humidification) is used to transport the steam to the alkali treatment plant. The cold source water is used to send the steam to the ash production equipment or its steam equipment, and the low-pressure condensate is returned to the treatment room. (3) It is also possible to use high-pressure steam to generate electricity and then use the above two principles to reuse the steam multiple times. 3, 4. The steam system inside the soda ash production plant can be reused multiple times and can be based on the following principles: The following principles are adopted: (1) After the superheated medium-pressure steam is cooled and humidified or after power generation, it is used to protect the steam from burning alkali, and the medium-pressure condensate is used to flash the flash steam to the low-pressure steam grid. The new steam is used to generate electricity and drive the motor pump. The low-pressure steam is used to dry the ammonium boiler heater (or ash boiler), and the steam generated in the low-pressure condensate can be used to go to the dilute liquid tower or other steam recovery equipment. (2) When the new steam does not generate electricity and drive the motor pump: the superheated medium-pressure steam can be used to dry the boiler, heater, condensate and unburned condensate to flash, and the low-pressure steam is collected. 4.3.5 The design adopts an annual average heating standard coal rate of 10.142 kg standard coal/million kilocalories (168.067 kg standard coal/million kilocalories).
4.3.6 The design can adopt
: The power supply conversion energy of the power grid is 1134027 kJ/kilowatt-hour (282S lower half/thousand hours) Standard loss network

Self-generated electricity is converted to 9332.38 joules/kWh (2229 kcal/kWh). The steam-driven pump power is converted to energy consumption of 5647.99 joules/kWh (1349 kcal/kWh). 4.3.7 After technical and economic comparison based on specific conditions, if an externally heated heavy alkali incinerator is used, the heat of the flue gas must be recovered. The recovery method can be waste heat steel yard, water preheater and air preheater and other equipment. The exhaust temperature can be designed according to the following figures.

4.3.8 For any production equipment using steam for indirect heating, the condensate recovery rate shall be between 60% and 80%. 4.4 The mechanical transportation design of soda ash plant can implement the "Principles and Regulations for Chemical Mechanized Transportation Design" and relevant regulations. 4.5 The water supply and return design shall comply with relevant design regulations and try to achieve multiple uses of one water, and make full use of the residual pressure of cooling water.
Technical Regulations for Energy-saving Design of Soda Ash (Trial) HGJ4-86
Preparation Statement
1 General Principles
1.1 The energy consumption indicators of this regulation are only applicable to the engineering design of newly built, rebuilt and expanded soda ash plants with a scale of more than 400,000 tons/year for nitrogen-alkali process, medium-sized plants with a scale of 400,000 to 400,000 tons/year, and medium-sized plants with a scale of 400,000 to 400,000 tons/year for combined alkali process. This regulation does not apply to the assessment of energy consumption of existing soda ash production plants. This regulation is different from the "Enterprise Energy Consumption Assessment Standard". The cost comparison of 20,000 tons/year and 40,000 tons/year combined alkali plants is as follows: 20,000 tons/year
Plant investment
Direct energy consumption.
Indirect energy consumption
More than 100 yuan/double ton
More than 14.5%
More than 12%
More than 28.3 yuan/double ton
The only advantage of a small-scale plant is that the total investment is small. Therefore, under normal circumstances, it is not appropriate to build a small combined alkali plant. The same is true for ammonia soda. Special circumstances must be approved by the superior supervisor. 1.2 The energy consumption level is stipulated in the annex of the Chemical Industry Ministry's (85) Chemical Salt Design Document No. 166: Level 1, the international advanced level of the late 1970s and early 1980s; Level 2: the domestic advanced level of the late 1970s and early 1980s; Level 3: the average advanced level of the late 1970s and early 1980s. The first-level energy consumption index is based on the fact that the technology of soda ash production plants is confidential and there is little data and information on its effectiveness. Therefore, it can only be based on the inspection reports, quotation materials and a very small number of published data in recent years. These data are incomplete and their calculation methods are unknown. Therefore, the first-level energy consumption standard is for reference only. It can only be required that the energy consumption index of the design of new (large, medium, small, modified, and expanded) projects should meet the first-level energy consumption index stipulated in this regulation. The energy consumption management work of domestic soda ash plants was established in the early 1980s, so the data listed is actually the level of the early 1980s. Due to the different specific conditions of each soda ash plant, it is not possible to use a certain broad data as the basis for formulating indicators. Due to the limitations of the specific conditions of the plant, more modification and expansion projects can adopt the second-level energy consumption index stipulated in this regulation. If there are specific special circumstances, and it is difficult to adopt the third-level energy consumption indicators and the energy-saving measures of this regulation, it must be approved by the superior competent department. 1.3 In recent years, various alkali plants have developed some new energy-saving processes and equipment, and the Ministry of Machinery has also produced a new series of energy-saving general-purpose electromechanical products. Therefore, the design of new construction, reconstruction and expansion should adopt new energy-saving processes, new equipment and energy-saving general-purpose electromechanical products.
1.4, according to the situation of my country's energy resources, the main energy resource is coal, and heavy oil or natural gas is generally not used as fuel. In the design of the soda ash plant, according to the situation of energy-consuming equipment, under reasonable process conditions, it is possible to achieve comprehensive utilization of steam, flashing of condensed water and multiple utilization of cooling water. 1.5 The design production amplitude of the soda ash plant is generally considered to be 10%. Large plants should consider a lower level to avoid excessive equipment capacity and increased energy consumption. The reasonable amplitude should be the design scale that meets the annual output, and this amplitude is still required due to management and other issues.
1.6 Strengthening measurement management, improving the level of automatic control and increasing the allocation rate of energy inspection instruments are important measures to reduce energy consumption. Now the energy management organizations of various soda ash production plants are sound, and energy detection instruments are basically all equipped, but there are still some phenomena of "eating big saws" without measurement. Therefore, in future designs, energy detection instruments should be installed in each process. The allocation rate should be greater than 95%. The automatic control level of soda ash production plants is also lower than that of other chemical plants, so improving the self-excavation level of soda ash plants is also an important topic in the future. 1.7 In addition to implementing these regulations, the design should also comply with the energy-saving regulations issued by the state and relevant regulations of the superior. When there is a conflict in the regulations, the national regulations shall prevail. 2 Comprehensive energy consumption index
2.1 Comprehensive energy consumption per unit of output: for the ammonia-soda method, it is the comprehensive energy consumed per ton of finished soda ash (light soda ash); for the combined soda method, it is the comprehensive energy consumed per ton of finished soda ash (light soda ash) and per ton of dry agricultural ammonium chloride (the production ratio of these two products is close to 1:1) (the energy consumption values reported by domestic combined soda plants also use the comprehensive energy consumed per ton of product). The calculation range is all the energy consumed from the entry of raw and auxiliary materials into the process unit to the storage of finished products. 2.2 This article is in accordance with GB2586~2589-81. 2.3 This article implements the national standard and the National Bureau of Statistics (84) Tonggongwuzi No. 362. The appendix to No. 362 on the average calorific value and standard coal conversion coefficient of several energy sources is as follows. Carbon source name

Among them, steam is calculated according to the discount coefficient of the specific design in the energy consumption calculation because the new design of the soda ash plant needs to be fully balanced and the heat energy is used multiple times. 2.4 The comprehensive energy consumption index is suitable for large and medium-sized ammonia-soda soda plants (medium-sized plants with a production scale of 40,000 to 400,000 tons/year and large plants with a production scale of more than 400,000 tons/year), because the plants built in recent years are all large and medium-sized ammonia-soda plants, and large and medium-sized plants are also suitable for the construction of ammonia-soda plants in the future from the perspective of technical economy and energy conservation. For soda ash plants with combined alkali process, this regulation is applicable to medium-sized plants (with a production scale of 40,000 to 400,000 tons/year), because most of the plants built in recent years are medium-sized plants. In the future, the construction of plants should also be medium-sized, which is in line with actual needs. The division of production scale is in line with the provisions of the "Regulations on the Classification Standards of Capital Construction Projects and Large and Medium-sized Projects" issued by the Ministry of Finance and Construction in 1978. 2.5 According to the provisions of the international GB2589-81 General Principles of Comprehensive Energy Calculation, comprehensive energy consumption is divided into three categories: total comprehensive energy consumption, unit (production plate) comprehensive energy, and comparable unit (product) comprehensive energy consumption. Total comprehensive energy consumption is the total energy consumption obtained after comprehensive calculation of various energy consumed by the enterprise during the planned statistical period. The total comprehensive energy consumption is related to the production of bottle film in the factory. It is not appropriate to stipulate a production scale. Therefore, the "Regulations" do not stipulate the total comprehensive energy consumption. For new soda ash plants of specific scale in the future, the product of unit (output) comprehensive energy consumption and annual output is the total comprehensive energy consumption. Comparable unit (output) comprehensive energy consumption is the comprehensive energy consumption calculated to achieve energy consumption comparability in the same industry. Since domestic soda ash plants have different external conditions, process flows and equipment are not exactly the same, and in the future, when designing new plants, their external conditions, process flows and equipment will definitely not be exactly the same as those of existing production plants, so the comparability is very small and there are difficulties in practical application, so only the unit output comprehensive energy consumption is stipulated. 2.6 Unit output comprehensive energy consumption indicators
2.6.1 Unit output comprehensive energy consumption of soda ash production plants in various countries The soda ash production technology of various countries in the world is confidential, and there is very little published information, and we have very little. Only a few data published based on investigations, quotations and relevant information in recent years can be listed for reference.

2.1 Comprehensive energy consumption per unit of output: for the ammonia-soda method, it is the comprehensive energy consumed per ton of finished soda ash (light soda ash); for the combined soda method, it is the comprehensive energy consumed per ton of finished soda ash (light soda ash) and per ton of dry agricultural ammonium chloride (the production ratio of these two products is close to 1:1) (the energy consumption values reported by domestic combined soda plants also use the comprehensive energy consumed per ton of product). The calculation range is all the energy consumed from the entry of raw and auxiliary materials into the process unit to the storage of finished products. 2.2 This article is in accordance with GB2586~2589-81. 2.3 This article implements the national standard and the National Bureau of Statistics (84) Tonggongwuzi No. 362. The appendix to No. 362 on the average calorific value and standard coal conversion coefficient of several energy sources is as follows. Carbon source name

Discount coefficient
Among them, steam is calculated according to the discount coefficient of the specific design in the energy consumption calculation because the new design of the soda ash plant needs to be fully balanced and the heat energy is used multiple times. 2.4 The comprehensive energy consumption index is suitable for large and medium-sized ammonia-soda soda plants (medium-sized plants with a production scale of 40,000 to 400,000 tons/year and large plants with a production scale of more than 400,000 tons/year), because the plants built in recent years are all large and medium-sized ammonia-soda plants, and large and medium-sized plants are also suitable for the construction of ammonia-soda plants in the future from the perspective of technical economy and energy conservation. For soda ash plants with combined alkali process, this regulation is applicable to medium-sized plants (with a production scale of 40,000 to 400,000 tons/year), because most of the plants built in recent years are medium-sized plants. In the future, the construction of plants should also be medium-sized, which is in line with actual needs. The division of production scale is in line with the provisions of the "Regulations on the Classification Standards of Capital Construction Projects and Large and Medium-sized Projects" issued by the Ministry of Finance and Construction in 1978. 2.5 According to the provisions of the international GB2589-81 General Principles of Comprehensive Energy Calculation, comprehensive energy consumption is divided into three categories: total comprehensive energy consumption, unit (production plate) comprehensive energy, and comparable unit (product) comprehensive energy consumption. Total comprehensive energy consumption is the total energy consumption obtained after comprehensive calculation of various energy consumed by the enterprise during the planned statistical period. The total comprehensive energy consumption is related to the production of bottle film in the factory. It is not appropriate to stipulate a production scale. Therefore, the "Regulations" do not stipulate the total comprehensive energy consumption. For new soda ash plants of specific scale in the future, the product of unit (output) comprehensive energy consumption and annual output is the total comprehensive energy consumption. Comparable unit (output) comprehensive energy consumption is the comprehensive energy consumption calculated to achieve energy consumption comparability in the same industry. Since the soda ash plants in China have different external conditions, process flows and equipment, and the external conditions, process flows and equipment of the new plants will definitely not be exactly the same as those of the existing production plants in the future, the comparability is very small, and there are difficulties in practical application, so only the unit output comprehensive energy consumption is stipulated. 2.6 Unit output comprehensive energy consumption indicators
