To ensure air quality and to participate in emissions trading programs, companies must meet the continuous monitoring requirements of local, state, national and global regulations. They must ensure that new and existing emissions sources in many different locations keep up with these complex and dynamic requirements, including periodic accuracy demonstrations and 100% monitor uptime. Traditional hardware continuous emissions monitoring systems (CEMS), however, require valuable plant space, frequent external audits and continuous maintenance, increasing the total cost of ownership. Pavilion’s Software CEM™ is the first Predictive Emissions Monitoring System (PEMS). Introduced in 1992 and approved by the U.S. EPA as a PEMS, Software CEM provides real-time emissions monitoring through correlations with existing instruments—resulting in accurate, fast emissions data at half the cost of a hardware CEMS.
