Editing Humidity (section)

=== Industry ===
High humidity can often have a negative effect on the capacity of chemical plants and refineries that use furnaces as part of a certain processes (e.g., [[steam reforming]], wet [[sulfuric acid]] processes). For example, because humidity reduces ambient oxygen concentrations (dry air is typically 20.9% oxygen, but at 100% relative humidity the air is 20.4% oxygen), flue gas fans must intake air at a higher rate than would otherwise be required to maintain the same firing rate.<ref>{{cite web|url=http://www.industrialcontrolsonline.com/training/online/everything-you-need-know-about-combustion-chemistry-analysis|title=Everything You Need to Know About Combustion Chemistry & Analysis – Industrial Controls|access-date=2015-01-23|archive-date=2020-01-10|archive-url=https://web.archive.org/web/20200110151007/http://www.industrialcontrolsonline.com/training/online/everything-you-need-know-about-combustion-chemistry-analysis|url-status=live}}</ref>
