Contain those VOCs -- Permanently

Journal Article · · Pollution Engineering
OSTI ID:207915
A permanent total enclosure (PTE) completely surrounds an emissions source so all volatile organic compounds (VOCs) are contained for discharge to a control device. If a facility meets the criteria for a PTE and all emissions are directed to a control device, the capture efficiency may be assumed to be 100% and the requirement to measure the capture efficiency is waived. The US Environmental Protection Agency (EPA) has been busy promoting the PTE concept, along with the use of temporary total enclosures (TTEs) and building enclosures (BEs), for measuring fugitive VOC capture efficiency. The gridlock of the 1980s and early 1990s has been broken and a scientifically sound method of measuring capture efficiency has been established. Used as a tool, the permanent total enclosure concept can help industry meet compliance schedules in many ways.
