Читать книгу Continuous Emission Monitoring - James A. Jahnke - Страница 57

Stationary source emissions in Mexico are regulated by the Secretaria del Medio Ambiente y Recursos Naturales (SEMARNAT – Secretariat of the Environment and Natural Resources). CEM systems were required in 1995 for glass manufacturing plants for monitoring NO_x, CO, and O₂. CEM systems for monitoring NO_x and O₂ were required for large thermoelectric plants in 1995, and SO₂ and opacity monitors were required in a 2011 revision of the standard. In 2002, CEM systems for CO and O₂ were required for waste incineration plants. In cement plants, if 15–30% of the fuels combusted are nonconventional fuels, continuous monitoring is required for CO, HCl, NO_x, SO₂, THC, and O₂ (CMIC 2020).

It is only required to validate CEM systems in the incineration and thermoelectric plant regulations, where the U.S. performance specifications of 40 CFR 60 Appendix B are referenced.
