Sinopec Ningbo Engineering and others have obtained a patent for a steam condensate recovery system that helps to significantly reduce the amount of desalinated water used. According to information from the Intellectual Property Office dated August 8, 2025, Sinopec Ningbo Engineering Co., Ltd., Sinopec Ningbo Technology Research Institute Co., Ltd., and Sinopec Refining & Chemical Engineering (Group) Co., Ltd. have been granted a patent titled “Steam Condensate Recovery System”; the approval number is CN223204757U, with the application date being August 2024. The patent abstract indicates that this utility model provides a device for the recovery and reuse of steam condensate, which includes: a steam condensate generation unit, a steam condensate collection unit, and a deoxygenation unit ； The steam condensate generation unit is connected to the steam condensate collection unit via a first pipeline, and is used to transport the steam condensate generated by the steam condensate generation unit to the steam condensate collection unit ； The steam condensate collection unit is connected to the deaeration unit via a second pipeline, and is used to transport the steam condensate collected by the steam condensate collection unit to the deaeration unit. By using this device, the heat from the steam condensate can be utilized to deoxidize the steam condensate as make-up water under the normal operating conditions of the deaerator; desalinated water is used only during startup conditions. This not only significantly reduces the amount of desalinated water required, but also allows the heat contained in the steam condensate itself to be reused in the deoxidization process.
