1 The role of chemical engineering and technology in promoting the chemical industry
The chemical industry is the embodiment of chemical engineering and technology in the industrial field. During the development of this industry, it has caused certain pollution to the atmosphere, land, water, etc., and has brought negative impacts on the ecological environment that cannot be ignored. Therefore, my country’s economic energy security and ecological environment protection are under great pressure at the present stage, and energy conservation and emission reduction have become issues that need to be focused on in my country’s economic development and environmental protection. my country is the second largest economy in the world. At the same time, as the largest developing country in the world, my country’s industrial level is already at the forefront of the world. As a solid foundation for my country’s industrial development, the chemical industry has made important contributions to promoting my country’s economic development. Environmental protection issues have gradually attracted widespread attention from all walks of life, and energy conservation and emission reduction in chemical industry production has become a research hotspot for relevant researchers. The implementation of energy saving and emission reduction in the chemical industry has the following functions: (1) The effective application of chemical engineering and technology in the chemical industry can improve the energy saving status in chemical production and reduce the impact of chemical production on the basis of various elements such as biotechnology and green environmental protection concepts.

2 Problems in the development of chemical engineering and technology
2.1 Insufficient research and application of chemical engineering and technology
In the past, the development of chemical engineering and technology was not based on overall planning, resulting in the consumption of a lot of resources, and there was a serious waste of resources during the use of resources. Insufficient management and control of resources has led to many obstacles in the future development of chemical engineering and technology. In addition, in the period of chemical engineering and process development, the relevant process technology has not been effectively improved and promoted, and the environment has not been effectively protected. Therefore, the harm to the environment is a problem that needs to be faced at present.

2.2 Large demand for chemical industry products
my country is a big agricultural country in the world. In recent years, with the continuous development of my country’s agriculture, the demand for agricultural production resources has continued to increase, especially the demand for chemical fertilizers has continued to increase, resulting in a huge production of such chemical products. On the other hand, due to the needs of economic development in some areas, there is still a certain degree of local protectionism, resulting in the imperfect industrial economic reform mechanism of the chemical industry, and will also have an adverse impact on the implementation of the national industrial structure adjustment policy, which has led to The production of chemical industry has been in a state of high energy consumption and high pollution for a long time, which makes the management of chemical industry difficult, and it is difficult to fundamentally control the pollution caused by chemical industrial production to the ecological environment.

2.3 Weak foundation for energy conservation and emission reduction in the chemical industry
my country’s statistics on energy consumption and pollution in the chemical industry and the governance mechanism are not perfect. The chemical industry is developing rapidly at this stage. It is difficult for the previous rules and regulations to meet the actual development of the current stage, and it is even more difficult to meet the actual needs of the chemical industry for energy conservation and emission reduction at the present stage. Some enterprises have not formulated corresponding plans and standards for energy conservation and emission reduction in the production process of the chemical industry. In addition, the statistics and management of the chemical industry are relatively weak, and there are few full-time energy and environmental protection management staff in my country. It is difficult to achieve accurate data statistics and effective energy-saving and emission-reduction governance for chemical industry production.

2.4 Energy saving and emission reduction technologies are relatively backward
The implementation of energy conservation and emission reduction in the chemical industry requires continuous innovation in production technology. The production scale of the chemical industry has continued to expand in recent years, but the research and application of energy conservation and emission reduction technologies are obviously insufficient. Even though some chemical industry manufacturing enterprises have applied energy-saving and emission-reduction technologies in the production process, most chemical industry manufacturing enterprises are unwilling to share energy-saving and emission-reduction technologies in the industry due to their own development and market competition. On the other hand, for industries that already have mature energy-saving and emission-reduction technologies, the state’s investment in energy-saving and emission-reduction in chemical industry production is somewhat lacking. Judging from the actual situation of the development of the chemical industry, the challenge of energy conservation and emission reduction is extremely severe. Relevant researchers still need to deepen their research and realize innovations in energy conservation and emission reduction technologies, so as to better implement energy conservation and emission reduction work in chemical industry production.

3 Ways of chemical engineering and technology to promote energy saving in chemical industry
3.1 Production of green and environment-friendly products
On the substantive level, the scientific application of chemical engineering and technology can, on the one hand, speed up the development of low-consumption chemical industry, and on the other hand, provide people with green and eco-friendly products, such as: biological fertilizers, pollution-free washing powder, cleaning Fuel etc. Through the application of green chemical engineering and technology, it is possible to manufacture eco-friendly products and restore the ecological environment. At present, many green and environmentally friendly products have been released and used in the field of production and life, which has greatly improved people’s health and is also conducive to the sustainable development of ecology. Based on this, in the current period, green chemical engineering and technology should be scientifically utilized, and its functions should be effectively utilized to scientifically improve the manufacturing process of chemical industrial products, reduce the damage to the natural environment caused by chemical production, reduce pollutant emissions, and strive to achieve the standard of zero emissions . Only in this way can the chemical industry and the ecological environment live in harmony, thereby promoting the long-term and healthy development of the entire society.

3.2 Application of cleaner production technology
Cleaner production technology plays a key role in the production of chemical industry. At present, various enterprises are also focusing on the development and application of this technology. At the same time, the relevant departments are also promoting vigorously. Cleaner production technology plays a huge role in promoting the environmental protection of chemical industry products. In the field of chemical industry, green engineering and industry is a brand-new production technology at present, which has made great breakthroughs, and its application in the chemical industry is relatively mature. However, green and clean production technology still needs to be improved in terms of production efficiency. Not only must the production process be continuously improved, but also clean energy and raw materials must be used to replace chemicals and certain chemical substances that cause environmental pollution. At the same time, it is necessary to optimize the process of chemical engineering, use more advanced technology and equipment, and strengthen the use of chemical raw materials to achieve the purpose of environmental protection chemical engineering and process. On this basis, using clean production technology, this method can not only effectively improve the utilization efficiency of chemical raw materials, but also reduce the pollution waste generated in the production process and reduce the impact on the environment, thereby reducing the environmental hazards of the chemical industry. For example, active disinfectant can dissolve sodium peroxide in water and convert it into water and oxygen. Not only does it have no harmful by-products, it has good bactericidal effect and is a very effective disinfectant. Cleaner production can greatly improve the technical level of the chemical industry, and at the same time make the clean technology widely used in other industries, and promote the continuous improvement of the production technology of chemical projects, and apply new technologies to industrial production. Both environmental protection and energy conservation are of great help.

3.3 Applied biotechnology
As a typical representative of green chemical industry technology, biotechnology has been widely used in the field of chemical industry, providing a new platform and a new perspective for the application of biotechnology. One is that biotechnology can decompose toxic substances through biotechnology, and biotechnology uses biological enzymes to transform them into specific organisms. That is to use the fermentation technology of microorganisms to turn them into organic compounds, so as to ensure that there will be no danger and no pollution to the environment during the production process. The second is to use microbial technology to treat industrial sewage and use biological enzymes to degrade it, reducing environmental pollution; thereby improving its governance effect, improving its treatment efficiency, and reducing its waste of resources. The application of biotechnology in the chemical industry has not only changed people’s cognition of chemical products, but also played a positive role in improving the process of chemical products. It is of great significance to the research and development of the chemical industry, and it can also realize the energy saving and emission reduction of chemical industry products. At the same time, in the process of green chemistry, the use of biotechnology can make the varieties of chemical industry products more diversified and more flexible. In various chemical processes, the selection of suitable biological enzymes plays an important role and significance in promoting the optimization and technical level of modern chemical industry production processes, improving chemical engineering technology, and improving product quality.

3.4 Application of green catalysts
The application of green catalysts can not only realize the effective combination of biotechnology and chemical technology, but also help the harmonious development of nature and science, and continuously improve the level of chemical technology. At the same time, the effective combination of modern biotechnology and green chemistry can improve the level of biotechnology in chemical engineering, deepen the research on genetic engineering, embryo engineering, and cell engineering, avoid the phenomenon of waste of chemical raw materials, and effectively solve the problem of environmental pollution. To this end, relevant staff should choose organic plant materials reasonably, so as to reduce the pollution of the chemical industry to the environment, and continuously develop the field of chemical industry development. In particular, the use of some natural catalysts and artificial catalysts can meet the needs of chemical production and effectively implement and implement the goals of sustainable development and energy consumption reduction.

3.5 Use harmless and non-toxic solvents
Some substances that pollute the environment appear in chemical engineering production reactions. The use of toxic catalysts, toxic solvents, and toxic raw materials in chemical production activities will pollute the natural environment. The use of toxic solvents in many chemical reactions will directly pollute the environment. Most of the toxic solvents are volatile, and once the internal organic matter escapes to the outside, it will cause serious impact along with the air in a large area. The use of toxic solvents needs to consider the pollution problems that the solvent may cause to water, soil, air and other resources in the application. Therefore, in order to prevent the large pollution caused by toxic solvents in chemical reactions, it is necessary to effectively use and study non-toxic solvents to achieve the goal of non-toxic production. Relevant personnel should study supercritical fluids in depth, so as to reduce the probability of pollution caused by toxic solvents. Supercritical fluids not only have the same density as liquids, but also have the same viscosity as gases. Strengthening the research of supercritical fluids plays an important guiding role in the research and development of non-toxic solvents. In the current stage of chemical production, in order to effectively protect the ecological environment and avoid excessive resource and energy consumption, it is necessary to analyze and study non-toxic solvents in depth, so as to promote the further development of green chemistry.

3.6 Optimizing energy use
The production process of the chemical industry needs to use a lot of energy, which will pollute the ecological environment. In addition, in the process of advancing industrialization, the structure of energy consumption has gradually changed from coal to natural gas and oil. However, the energy structure in the field of chemical industry production is difficult to complete the conversion in a short period of time. Therefore, in the work of energy conservation and emission reduction in the chemical industry, priority should be given to adjusting the energy structure. From the use of energy such as natural gas and oil to the use of renewable energy such as solar energy and water energy, the ecological environment can be protected while realizing economic development. As a large industrial production country, my country must consider the carrying capacity of the ecological environment. In order to ensure the sustainable development of the chemical industry and our country’s economy, only by continuously increasing the investment in new energy and chemical technology can we improve the energy efficiency of the chemical industry, and then contribute to the protection of The ecological environment has laid a solid foundation.

4 Epilogue
To sum up, in order to solve the environmental pollution caused by the chemical industry, we should promote the development of chemistry towards green and environmental protection, produce green and environmentally friendly products, reduce the waste gas and toxic and harmful gases produced by the chemical industry, improve the utilization rate of resources, and reduce resource and energy consumption. Under the background of our country’s vigorous promotion of energy conservation and environmental protection, chemical engineering practitioners need to quickly adapt to the direction of the development of the times, promote green chemistry in accordance with the country’s strategic requirements for environmental protection, choose chemical processes and technologies that will not pollute the environment, and save engineering.
