Study on Use of Mixed Synthetic Heat Transfer Fluid in an Enterprise
The heat transfer fluid is a widely used medium for excellent heat conduction and used in some industries needs to meet the special process temperature requirements(operating temperature up to 340 ℃).The characteristics of the two-component mixed heat transfer fluid used in an industry and inspection report surveys of the heat transfer fluid over the years were analyzed,and the performances of the mixed heat transfer fluid in use were tested.According to the analysis,the mixed heat transfer fluid can meet certain comprehensive application char-acteristics under the technological conditions of the industry(such as low pour point,high operating temperature,low saturated vapor pres-sure,and convenient operation without heat tracking).Meanwhile,the mixed heat transfer fluid has stable changes in various indicators over the years,and no mutations have been found.But in the process of use,there have been residual carbon value,acid value exceeding the phe-nomenon,among which the highest carbon residue value was 3.480 8％,and the highest acid value was 1.002 6 mg KOH/g.The investigation found that the recycling treatment can effectively restore the exceeded value to the allowable standard.The flash point,kinematic viscosity,re-sidual carbon and acid values of the mixed heat transfer fluid were tested,and the results showed that the test performance was within the per-missible range except that the flash point value of one sample reached the safety warning standard.Finally,in order to ensure the safe operation of this kind of mixed heat transfer fluid,we put forward relevant suggestions for the work of the heat transfer fluid mixed addition and regenera-tion unit,enterprise management and operation personnel,and heat transfer fluid inspection unit.
