| Abstract: | The on - line cleaning of heat exchanger is a new technology which contains the chemical, physical, mechanical and other disciplines. This new technology can be applied to extend enterprise production cycle and improve production efficiency. The application of RFC - 2 chemical cleaning sol- vent in the 10 million t/a often pressure - relief devices to cease was introduced in the pa- per. Technology of chemical on the device for cleaning process for cleaning technology and in large plant application advantages and shortcomings were summarized. At present, chemical cleaning tech- nology has been widely used in petroleum, chemical industry, machinery industry, etc. |
