Technical assistance: Condensate water quality treatment technology

This post was last edited by hesonchang214 on 2010-11-18 07:59. Dear seniors: The iron ion concentration in the condensate of our company is around 90 μg/L, with a flow rate of about 50 m3/h. We aim to reduce this concentration to less than 20 μg/L so that the condensate can be reused in the high-pressure boiler (with a pressure of 9.8 MPa and a capacity of 130 t/h). Could experienced seniors advise on which treatment process would be suitable for removing iron ions? Our company currently uses precision filters, but their effectiveness is not very good.

There is a treatment method that makes use of the internal energy of condensate, and it is used in many Sinopec refineries with very good results. By employing active molecular membrane ultrafiltration and composite carbon fiber adsorption materials with numerous functional groups, it is possible to effectively remove various hydrocarbons and their derivatives in emulsified or dissolved form from condensate, even when the temperature of the steam condensate does not drop to room temperature. 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.
Reply to 3# zxy651908: Hello, using the process you mentioned, how much investment would be required for a situation like ours at our company? Could you provide some detailed information? My contact number is 15276221581.
Reply to 4# wanghuiping: Our company originally intended to implement it, but it hasn’t been done yet due to various reasons. You should consult the equipment manufacturer for this; the specific price seems to be related to the processing capacity. You can find their contact information by searching for “Zhongneng Huankē” online. We’ve done some research on them, and they seem to be quite good
