Analysis and solution measures of slime blockage in circulating water system of refining and chemical enterprise
The problems caused by large amount of slime blocage in circulating water system of a refinery enterprise were analyzed.On the one hand,measures such as optimizing the cleaning and stripping scheme,en-hancing the cleaning,stripping and dissolution effect of the slime blockage,shorting the cleaning cycle and time-ly adjusting the sterilization plan,were taken to control the bacterial growth;on the other hand,measures such as adjusting the pH value and alkalinity,reducing the concentration ratio and optimizing the scale inhibition and dispersion agent were adopted to prevent scale formation.The problem of slime blockage in circulating system was solved,the corrosion rate was controlled well and normal operation of circulating water system was ensured.
