Application of tower diameter changing in resin fractionation

Through the heat recovery of condensation water in oil refining plant and the water treatment recycling,it can reduce the energy consumption of production.In this project,according to the different quality of condensate water,different process is adopted.Specifically,the static oil separation process is used to remove the suspended oil in the condensation water.In addition,the emulsified oil and suspended oil adsorption,iron removal,heat recovery,the number of ion(anion and cation) and conductivity value overweight treatment,deoxygenization treatment also can be achieved.It make the index of condensation water after treatment reach deoxygenated water index,meeting the boiler feed water requirement.To ensure the effective regeneration of the failure resin,effective separation technique,equipment and control mode are adopted to deal with failure resin based on the technique of Na + exchange process.So the process water is qualified and the resin recruitment reduces.Through the practical production operation,the process results reach the design requirements and achieve a satisfactory effect.
