Ambient air quality monitoring solutions for benzene fence-line monitoring
To monitor benzene emissions can be a challenge, but OPSIS makes it easy. Benzene is an aromatic hydrocarbon liquid that evaporates quickly if exposed to ambient air. It is one of the most commonly used substances in the chemical industry and it is known to cause cancer. For this reason, refineries in the United States must start monitoring fugitive emissions of benzene from January 30, 2018. This is part of the 2015 U.S. EPA Petroleum Refinery rule. In case a yearly rolling average of benzene concentrations ...
