Oxidizers for Control of VOCs And Air Toxics

摘要

State and federal regulations require that a range of industries control organic vapors from their processes. Applications exist in food processing, finishing, ethanol/biodiesel fuels, plastics/rubber, packaging/printing, Pharmaceuticals, refining, electronics, pulp/paper/engineered wood and other industries. This article covers the major issues involved in design and specification of vapor control systems. Controls for volatile organic compounds - also referred to variously as VOCs, air toxics, organic vapors and SVOCs - generally are required to provide greater than 95 percent removal. In addition to old limits such as 100 tons/ year of VOCs per facility, some com- pounds are subject to more stringent limits of 10 tons/year, depending on the severity of air pollution in a non-attainment area and the emitted compound. In addition to production emissions, fugitive emissions such as those from tank storage, valve stem leaks and pump shaft seals also are regulated.
