AI Technical Summary
Existing technologies lack the ability to monitor and automatically resolve the wax buildup in methanol water coolers in real time, forcing companies to make difficult trade-offs between preventative maintenance and production continuity. Traditional methods suffer from frequent downtime, unstable cleaning results, and high maintenance costs.
By employing a steam ejector and a wax deposition early warning system, the steam ejector is automatically triggered to perform online wax removal by real-time monitoring of temperature and pressure parameters. Combined with an anti-wax deposition coating, automated wax removal is achieved.
It enables automatic dewaxing without shutting down the machine, improving heat exchange efficiency, reducing maintenance costs, extending equipment life, and enhancing production continuity and economic benefits.
