The analysis on gas heater valve

Acetic acid as important chemical intermediates, has been widely used, and its derivatives are hundreds of species. Growing downstream Gas Heater Valve acetate fibers, paints, adhesives and other industries and downstream industry chain development efforts acetate continued to increase for the development of Chinese acetic acid industry provides a good background environment and opportunities.
     Because of two devices in the selection and amount of catalyst synthesis loop size respects fundamentally different from the first phase, so the process operation there is a big difference, especially in the gas heater valve synthesis reactor since the circulation line with strict temperature requirements . To be able to achieve the desired operating results, the temperature control loop pipeline between 185 ~ 195 ℃, pressure rating between 2.8 ~ 4.0MPa. But in most of the use of the pipeline is lined with ordinary type PTFE (polytetrafluoroethylene) material plug, when the system is running two to three months time to shut down for maintenance, unable to find the Gas Heater Control Valveclosed, should not be process. Examination revealed plug lined with varying degrees of loss, more serious tear occurred. In order to ensure normal production, this problem is analyzed and processed.
