Abstract:
The chemical cleaning agent,QX-211 is developed to clean scale in the steam condenser in the Thermal Power Plant without stopping operation. It consists of HEDTA,organic acid,corrosion inhibitor and other cleaning assistant agent.The prescription has been proved to have the following characteristics such as easy operation,high efficiency,low corrosion and effective cleaning under normal operations by dynamic simulated cleaning experiment and in situ application. In addition the wastewater is easy to be treated and no harm to the environment.
