Abstract: Due to the imperfect steam trap system, serious leakage of steam, less recovery of condensed water happened in Yulin refinery, and the poor quality condensed water could not be used as boiler make-up water as well. By adopting energy saving technology of steam pipe network, which included a combination of back pressure return and pressurized backwater, the condensed water was fully recovered and after fine treatment, it could be used as boiler make-up water. Since then, steam and water resource were saved, the utilization of low temperature heat was improved, operations were stable and production cost was reduced in some extent.

Key words: steam pipe network, condensed water, recovery
