| Title: |
Control emissions of benzene from natural gas dehydrators |
| Text: |
"Emissions from glycol dehydrators can be reduced by: optimization of operations; equipment modifications or replacement; and/or, addition of emission control equipment. Emission controls such as condensers, flare stacks, and incinerators for still column vent vapors have been installed by industry at some locations." |

| Cost-Benefit Analysis: |
"EPA has calculated that by doing so, the potential savings for a dehydrator unit can range from $260 to $26,280 per year.[9]" |
| BMP Efficacy: |
"Research by the U.S. EPA has indicated that operators of glycol dehydrators often maintain a circulation rate that is at least two times higher than is needed to remove enough water from the gas. Therefore, companies can reduce their glycol use by performing simple calculations to determine the minimum circulation rate needed. By doing so, they will lose less methane to the atmosphere; improve the dehydrator unit efficiency; and decrease fuel pump use." |
