AI Technical Summary
Technical Problem
Existing purging systems for methanol tankers suffer from high nitrogen consumption and excessive purging, resulting in wasted storage space.
Method used
A digital twin-based intelligent purging system is adopted, which combines a visualization sensing module, an intelligent control module, and a purging module. By using a combination of water pumps and nitrogen purging, the purging time and effect are optimized. Pressure sensors, methanol sensors, and high-definition cameras are used for real-time monitoring, and the nitrogen purging time and method are dynamically adjusted.
Benefits of technology
It optimizes nitrogen consumption, avoids excessive purging, improves methanol cleaning efficiency, and saves storage space and energy.
