High-temperature condensate treatment
Thread Content
Our research institute plans to undertake a project; some time ago, we went together with our supervisors to domestic petrochemical companies to examine the high-temperature condensate recovery and treatment processes. Visits were made to several locations such as Daqing, Lanxi Petrochemical, Fujian, and Qingdao; several different processing methods were employed, each with its own advantages. Based on actual operation results, it turns out that treating oil and iron separately yields relatively better results. The quality of the water produced generally meets the standards required for high-pressure or medium-pressure boilers, and it is also possible to treat high-temperature condensate water at temperatures below 110 degrees Celsius. The process for removing oil and iron simultaneously performs reasonably well in terms of oil removal during actual operation, but the iron removal effect is average; it is difficult to eliminate iron in its ionic form.
We use electromagnetic iron removal filters here, and they work very well – the iron content in the output is completely within acceptable limits.
There are several processes available for oil and iron removal, with operating costs of over 0.1 yuan per ton; if lower operating costs and better results can be achieved, further research is possible. Personally, I think it’s quite difficult to break through existing technologies
For this, a special resin for oil removal can be used, and a special resin for iron removal is used for removing iron.

High-temperature condensate can exchange heat with the heat transfer water, allowing the heat to be utilized first; if the quality of the condensate is good, it can then be used directly as a water source in the deaerator.
