Synthesis and field test of defoamer for amine solution in a terminal treatment plant in Bohai Sea
In view of the characteristics of amine solution regenerated foam in a terminal treatment plant in Bohai Sea,laboratory reagent screening work was carried out and field tests were carried out.The results show that the selected polyether-polyether modified sili-cone oil defoamer X-25 is more suitable for amine solution treatment in a terminal treatment plant in Bohai Sea than the emulsion defoamer in use.Compared with in-use reagents,X-25 with low viscosity,can be directly injected characteristics.The recommended dosing concen-tration is 20 mg/L,which can be used as continuous dosing or impact dosing.Compared with in-use dosing,it can greatly reduce the workload of field operation,it has a good prospect of popularization and application.
