On April 18, the 25th China Environment Expo, Asia's flagship environmental protection exhibition, co-organized by the Chinese Society of Environmental Sciences, the All-China Environmental Services Chamber of Commerce, Messe München Group and China Trade München Exhibition (Shanghai) Co., Ltd., opened grandly at the Shanghai New International Expo Center.
As one of the largest and most influential environmental protection exhibitions in Asia, this year's Environment Expo, with the theme of "Innovation Driven Green Development", attracted hundreds of exhibitors and tens of thousands of visitors from dozens of countries and regions around the world. During the three-day exhibition, the latest technologies, products and solutions in the field of environmental protection were all unveiled, outlining a beautiful blueprint for us to lead a sustainable future with green innovation.
Innovative technologies lead green transformation
In this year's Environmental Expo, innovative technology is undoubtedly the most eye-catching keyword. Major exhibitors have demonstrated their cutting-edge technologies and innovative achievements in the field of environmental protection, covering a variety of fields such as air governance, water treatment, solid waste disposal, and soil remediation. Among them, environmental protection technologies originating from China have attracted much attention.
For example, Eco Nova Group, a leading domestic environmental protection company, demonstrated its ethylene oxide waste gas treatment application technology. This technology can reduce ethylene oxide waste gas emissions to ultra-low levels, far below national standards. This technological breakthrough not only demonstrates China's innovative strength in the field of environmental protection, but also provides a new solution for air pollution control in China and even the world.
There are many options for ethylene oxide waste gas treatment technologies, each with its specific advantages and limitations. Here are some common ethylene oxide waste gas treatment technologies and their respective pros and cons:
01.Activated carbon adsorption method:
Advantages: High efficiency - has high adsorption efficiency for ethylene oxide.
Simple operation: The system structure is simple, easy to operate and maintain. Disadvantages: The activated carbon needs to be replaced or regenerated regularly, which increases the operating cost. The treatment efficiency will decrease after the activated carbon is saturated.
02.Catalytic combustion method:
Advantages: High treatment efficiency - can effectively convert ethylene oxide into carbon dioxide and water.
Suitable for high-concentration waste gas: good treatment effect on high-concentration ethylene oxide waste gas.
Disadvantages: High energy consumption - requires a lot of energy to maintain the high temperature required for the reaction.
High initial investment: high equipment cost and installation cost.
03.Biological method:
Advantages: Environmentally friendly - using microorganisms for treatment, no secondary pollution.
Low cost: relatively low operating and maintenance costs. Disadvantages: Low efficiency - slow processing speed, not suitable for high-concentration waste gas. Sensitive to environmental conditions - microbial activity is affected by factors such as temperature and pH.
04.Plasma method:
Advantages: High efficiency - rapid decomposition of ethylene oxide, fast reaction speed.
Wide application range: good treatment effect on waste gas of various concentrations. Disadvantages: High energy consumption - high operating cost, especially electricity consumption.
Complex equipment: high technical requirements, complex equipment maintenance and operation.
05.Absorption method:
Advantages: Multiple pollutants can be treated simultaneously - specific absorbents can be designed to target multiple pollutants.
Equipment is relatively simple: the technology is mature and the equipment is easily available.
Disadvantages: Secondary pollution may occur - the absorbent needs to be properly treated, otherwise it may cause secondary pollution.
Limited efficiency: the efficiency may not be high for very low concentrations of waste gas.
06.Condensation method
Advantages: Direct collection - ethylene oxide in the waste gas can be directly collected for easy recycling.
Simple equipment: The technology is relatively simple and easy to implement. Disadvantages: Low temperature requirements - requires lower temperatures and higher energy consumption. Only suitable for high concentrations: Not effective for low-concentration exhaust gas.
AMCR (Adsorption, Membrane separation, Catalytic oxidation, and Recovery) waste gas treatment technology is a comprehensive waste gas treatment method that combines multiple technologies such as adsorption, membrane separation, catalytic oxidation and recovery. Through this comprehensive technology, ethylene oxide can be efficiently treated specifically, reducing environmental pollution and bringing economic benefits.
The launch of this technology is undoubtedly the biggest highlight of this exhibition. It not only brings new ideas and methods to ethylene oxide processing, but also breaks key gaps in the field on a global scale.
The Environmental Expo is not only a platform for displaying technologies and products, but also an important window for spreading environmental protection concepts and promoting social change. The Environmental Expo also builds a platform for dialogue between government and enterprises and international exchanges. Through summit forums, roundtable meetings and other forms, representatives from the government, enterprises, academia and the public jointly discuss environmental issues, share governance experiences and build consensus on environmental protection. This model of multi-party participation and collaborative governance provides a useful reference for promoting the modernization of environmental governance systems and governance capabilities.
The 2024 Shanghai Environmental Expo will allow us to see the beautiful picture of green innovation leading to a sustainable future. Advanced environmental protection technologies, innovative green products, and increasingly strengthened environmental awareness are jointly promoting the transformation of society to green and low-carbon. Standing at a new starting point, we have reason to believe that on the road of green development, China and even the world will continue to make new progress and jointly create a beautiful future of harmonious coexistence between man and nature.
