High-temperature condensate water
Thread Content
Recently, I was working on a project involving the recovery of high-temperature condensate from an entire plant at 120 degrees Celsius; this condensate, after being treated to meet the standards for high-pressure boilers, is sent to a deaerator for deoxygenation, resulting in deoxygenated water. Is there such a condensate treatment equipment capable of handling high-temperature condensate at 100°–120°? Can it meet the standards?
Sinopec has specialized departments responsible for promoting the recycling of condensate water, including those that treat the condensate to meet the requirements for boiler water.
The high-temperature condensate water treatment technology developed by Beijing Zhongneng Huanke Technology Development Co., Ltd. utilizes active molecular membrane ultrafiltration and composite carbon fiber adsorption methods with numerous functional groups; this allows for the effective removal of various hydrocarbons and their derivatives in emulsified or dissolved form from condensate water, without the need to cool it. At the same time, under the action of the functional groups on the active molecular membrane and the composite carbon fibers, divalent and trivalent metal ions in water are removed. This process features technical advantages such as simple operation and management, good high-temperature adsorption performance, low treatment costs, as well as the ability to facilitate automatic control and online monitoring. Recommended inlet water parameters: total iron ≤ 0.5 mg/l, hardness ≤ 50 µmol/l, oil content ≤ 80 mg/l, COD ≤ 50 mg/l, pressure ≤ 0.5 MPa, temperature ≤ 120°C
Regarding the recovery of high-temperature condensate water, our company has also conducted research in this area, and Zhongneng Huanke performs fairly well.
First, a heat exchanger is used to lower the water temperature so that it meets the requirements for recovery; afterwards, another heat exchange process is used to raise the temperature of the treated water, and inevitably some heat is lost in this process.
