AI Technical Summary

Technical Problem

Existing methods for designing scale inhibitor formulations are inefficient, making it difficult to reveal the synergistic and antagonistic effects between scale inhibitor components. Furthermore, conventional optimization methods neglect corrosion inhibition performance and adaptability to dynamic operating conditions, resulting in poor performance of the formulations in actual circulating water systems.

Method used

A method for optimizing the formulation of scale inhibitors for circulating water based on mixing design was adopted. Effective raw material components were screened by obtaining water quality parameter reports, simplex centroid design was carried out, and the test samples were mixed and prepared. The theoretical comprehensive performance index was calculated through scale inhibition performance testing, and finally, water circulation experiments were conducted to verify the deviation and confirm the target formulation.

Benefits of technology

This improves the efficiency and overall performance of scale inhibitor formulation optimization, ensures the effectiveness of theoretical results under actual working conditions, avoids the risk of theoretically optimal formulations failing in industrial applications, and achieves balanced optimization of scale inhibition and corrosion inhibition performance.
