【Haichuan’s Best Practices】Adopting a \"filter + mixed-bed\" treatment process to remove salt content from the water supplied to the turbine condensate system
Thread Content
Recently, a turbine condensate recycling device applied for by Yulin Refinery was granted a **patent license. It is reported that the original 130 tons per hour turbine condensate treatment system in Workshop 1 of Yulin Refinery relied primarily on pre-filtration, which was unable to effectively remove salts from the incoming water. Moreover, this pre-filtration process required regular regeneration, resulting in high water and energy consumption as well as increased operating costs for the system. In particular, when there were fluctuations in the temperature and quality of the incoming water, it was not possible to achieve 100% recovery of the condensate. To address the aforementioned issues, the research team modified the pre-filtering oil and iron removal process to a \"filter + mixed-bed\" treatment process. After the renovation, substances such as suspended solids, colloids, corrosion products, and oils in the condensate water were effectively removed, and the quality of the water after desalination using mixed-bed reactors met all the specified requirements.

Impurities brought in by the condensate water: The steam that has done work is cooled in the condenser by cooling water, turning into condensate water. When there are leaks in the condenser, cooling water will leak into the condensate. Cooling water is generally raw water that remains untreated or is only partially treated, containing high levels of various impurities. When operating normally, the leakage rate of the condenser is 0.01%~0.05% or lower. The leaks in the condenser usually occur at the joints where the tubes are connected to the tube sheet; when the tubes crack, perforate, or break, more cooling water will leak into the condensate. . Due to the high salt content in the cooling water, even a small amount of leakage will cause the salt content in the condensate to increase rapidly. For example, if the salt content in the cooling water is 500 mg/L and the leakage rate is 0.2%, the salt content in the condensate will increase by 1 mg/L, thereby significantly deteriorating the quality of both the condensate and the feedwater. Cooling water leakage, which contaminates the condensate water, is one of the main ways in which impurities enter thermal systems.
