Traditional methods such as thermal, stripping, and vacuum deaeration are mature but limited by energy consumption, system complexity, and adaptability. In contrast, membrane deaeration has emerged as a promising alternative due to its energy efficiency, compact design, and superior adaptability. Recent advances in membrane materials and module configurations have enabled efficient dissolved oxygen removal to ppb levels under mild operating conditions. This review summarizes the mechanisms, equipment, and application features of conventional methods, and outlines progress in membrane deaeration regarding mass transfer, module design, and process integration. Future development will focus on multi-technology coupling, mass transfer intensification, and intelligent control to achieve ppb-level oxygen removal.<\/jats:p>","DOI":"10.3390\/membranes16070244","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T09:00:52Z","timestamp":1784278852000},"page":"244","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Progress on Physical Processes for Boiler Feedwater Deoxygenation"],"prefix":"10.3390","volume":"16","author":[{"given":"Binglin","family":"Li","sequence":"first","affiliation":[{"name":"State Grid Shaanxi Electric Power Co., Ltd., Ultra-High Voltage Company, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andong","family":"Jian","sequence":"additional","affiliation":[{"name":"State Grid Shaanxi Electric Power Co., Ltd., Ultra-High Voltage Company, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayu","family":"Lu","sequence":"additional","affiliation":[{"name":"State Grid Shaanxi Electric Power Co., Ltd., Ultra-High Voltage Company, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaxi","family":"Lv","sequence":"additional","affiliation":[{"name":"State Grid Shaanxi Electric Power Co., Ltd., Ultra-High Voltage Company, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"272","DOI":"10.1016\/j.enpol.2017.10.006","article-title":"Cost comparisons for wind and thermal power generation","volume":"112","author":"Ian","year":"2018","journal-title":"Energy Policy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"112955","DOI":"10.1016\/j.enpol.2022.112955","article-title":"Carbon emission efficiency of thermal power generation in China: Empirical evidence from the micro-perspective of power plants","volume":"165","author":"Tao","year":"2022","journal-title":"Energy Policy"},{"key":"ref_3","first-page":"143","article-title":"Research on the development path of China\u2019s thermal power generation technology based on the goal of \u201ccarbon peak and carbon neutralization\u201d","volume":"44","author":"Zhang","year":"2023","journal-title":"Power Gener.
