Green scale inhibitors and dispersants are a class of chemicals that are of great significance in the field of water treatment. They can effectively prevent the formation of scale and have the characteristics of environmental protection and biodegradability. The following is an overview of the research progress on green scale inhibitors and dispersants:
1. Oilfield scale control: The issue of oilfield scale has always been one of the main issues in ensuring oilfield flow. Although traditional phosphorus containing scale inhibitors have significant effects, they have a negative impact on the environment due to their involvement in eutrophication processes. Therefore, green scale inhibitors such as polyaspartic acid (PASP), polyepoxysuccinic acid (PESA), plant extracts and their derivatives have been developed to replace traditional products.
2. Application in the field of water treatment: In water treatment fields such as circulating cooling water systems, seawater desalination devices, and industrial water for secondary oil recovery, scaling problems seriously affect water use and treatment efficiency, and may even damage equipment and create safety hazards. Green scale inhibitors have gradually become a focus of research and development due to their environmental characteristics.
3. Enhancing environmental awareness: With the increase of environmental awareness, the use of phosphorus containing scale inhibitors is restricted, prompting researchers to develop non-toxic, efficient, and biodegradable green scale inhibitors. These new scale inhibitors not only effectively alleviate the scaling problem of circulating water, but also conform to the concept of green development.
4. New green scale inhibitors: In recent years, some new and efficient green scale inhibitors have been reported, such as polyaspartic acid, polyepoxysuccinic acid, and gamma polyglutamic acid. They have the characteristics of being non-toxic, efficient, and biodegradable, representing the development trend of research in the field of water treatment [^ 6 ^].
5. Application in oilfield development: In oilfield development, green scale inhibitors such as polyepoxysuccinic acid and polyaspartic acid are becoming the focus of research due to their environmental friendliness and high temperature resistance.
6. Research status and application progress: Green scale inhibitors have become the development direction of scale inhibitors in the 21st century due to their high scale inhibition performance, good biodegradability, and non toxicity. The research and application progress of the system indicates that the types, properties, and application prospects of green scale inhibitors are broad.
These developments demonstrate the importance of green scale inhibitors in environmental protection and industrial applications, as well as their potential in future development. With the continuous progress of technology and the increasingly strict environmental regulations, the research and application of green scale inhibitors will continue to expand.pesa
