Abstract: Regenerative thermal oxidizer (RTO) technology has been applied in low temperature methanol washing tail gas treatment,
which has proved that RTO can treat the tail gas reliably and stably and meet the requirement of GB 31571—2015 Emission
Standard of Pollutants for Petroleum Chemical Industry. In the system, RTO can control NO_x generation in a high-temperature
process and NO_x emission is low. RTO can achieve high heat recovery efficiency, and achieve positive benefits through the waste
heat recovery and utilization of by-product steam.

Key words: RTO; low temperature methanol washing; NO_x; waste heat recovery
