Application of green chemical technology in chemical engineering and technology

Taking the production of gasoline as an example, the shortage of oil and gas resources has led to the rising price of gasoline, and fuel vehicles have also caused great damage to the ecological environment. Therefore, automobile companies and chemical companies have begun to seek more high-quality gasoline alternatives, such as ethanol, electric energy and other new green fuels, which are the embodiment of environmentally friendly products. Degradable plastics are also a new type of environmentally friendly products that have emerged in recent years. With the gradual implementation of China's plastic ban, the research and development speed of degradable plastics has also been accelerated. Degradable plastics, according to their characteristics, can be divided into photodegradable plastics, biodestructive plastics, and biodegradable plastics. Biodegradable plastics can replace polyethylene and polypropylene to reduce white pollution. Coatings are also one of the important chemical products, common coatings are solvent-based coatings, water-based coatings and so on. Although solvent-based coatings have the advantages of high viscosity and fluidity, convenient storage, etc., the solvent-based coatings contain a large number of volatile organic compounds, fungicides, organic pigments, which will cause serious damage to the ecological environment and human health. High solid content solvent-based coating (HSSC) is a new type of coating developed on the basis of ordinary solvent-based coating, which reduces the amount of organic solvent, optimizes the coating process and production method, and improves the solid composition, and has been widely used in recent years. Water-based coatings are relatively low in cost and risk, but water-based coatings have high enthalpy of water vaporization, are susceptible to relative humidity, poor water resistance, and many aspects can be optimized. Solvent-free coatings and powder coatings are also the products of the development of green coatings, which are widely used in ordinary brush and spray processes. Among them, powder coatings have more advantages and will become one of the important trends in the development of green coatings in the future.

4.4 Optimize green chemical production process and environment

Green chemical technology is also of great significance to promote the optimization of chemical production process. In the new era, chemical enterprises should realize that the weight of economic benefit and output has declined in the process of producing chemical products. High-quality chemical enterprises should not only bring good economic benefits and objective output, but also promote the progress of green chemical technology and lead the development of environmental protection technology in the chemical industry. Therefore, green chemical technology occupies an important position in chemical production in the new era. Taking heat consumption as an example, most chemical industries have a relatively high demand for heat. In order to save costs and reduce processes, most chemical enterprises use single heating equipment and methods, which meet the production needs of chemical enterprises, but also cause the waste of resources and the loss of heat. Chemical enterprises should output heat according to their own needs, enrich the types and types of heating equipment, and avoid the waste of heat in the production and transmission process. In addition, the use of variable frequency motors and other equipment to reduce energy consumption in the chemical production process and reduce the loss of power resources can also effectively reduce environmental pollution [15]. With the international energy crisis becoming more and more serious in recent years, the phenomenon of rising raw materials due to resource shortage has become more and more common. The application of green chemical technology is imminent, and the majority of chemical enterprises must pay attention to the application of green chemical technology in the new era, improve the utilization efficiency of materials, and realize the recycling of resources. Green chemical technology can not only improve the economic benefits of enterprises, but also bring good social benefits for enterprises, and promote the healthy and sustainable development of enterprises, which needs to attract our attention.

4.5 Promoting the recycling of chemical waste

The treatment of organic chemical waste has always been a difficult problem for chemical enterprises to carry out chemical production. If the organic chemical waste is not properly treated, it will cause serious damage to the environment. Green chemical technology should pay attention to the recovery and utilization of organic chemical waste to avoid the problem of waste deposition in the past chemical production process. In fact, the deposition of waste has caused a serious threat to the environmental safety of chemical production sites, so we should pay attention to the application of green chemical technology in organic chemical fertilizers, and promote the improvement of the ecological value of the chemical industry.
