Regenerative thermal oxidizer process flow diagram.

Flaring is a. Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016. A regenerative thermal oxidizer or rto builds on the thermal oxidation operating principles but at greatly enhanced fuel efficiency. Regenerative thermal oxidizers from the cmm group are designed to destroy air pollutants emitted from process exhaust streams at temperatures ranging from 815 c 1 500 f to 980 c 1 800 f.

Though thermal oxidation is a simple process capable of very high voc destruction efficiency the fuel consumption and cost to heat the voc laden process can be severe. Table 2 1 provides capital cost estimates for thermal oxidizers in several industry source categories. Ventilation air methane thermal oxidizers are used to destroy methane in the exhaust air of underground coal mine shafts. An rto burns very lean waste gases without using much fuel.

An rto consists of two or more heat. The process begins with a high pressure supply fan that forces exhaust fumes into the regenerative thermal oxidizer.

Co 2 is 25 times less potent than methane when emitted into the atmosphere with regards to global warming.

Operating temperature is about the same as a normal thermal oxidizer say 1600of but the hot flue gas passes through a heat exchange module before reaching the stack. About rtos regenerative thermal oxidizers summary. Methane is a greenhouse gas and when oxidized via thermal combustion is chemically altered to form co 2 and h 2 o. A regenerative thermal oxidizer rto is a piece of industrial equipment used for the treatment of exhaust air the system is a type of thermal oxidizer that uses a bed of ceramic material to absorb heat from the exhaust gas it then uses this captured heat to preheat the incoming process gas stream and destroy air pollutants emitted from process exhaust streams at temperatures ranging from 815.

Inlet switch valves direct the pollutant laden air into one of the energy recovery canisters. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated. This voc abatement technology utilizes ceramic media packed into vertical canisters as a high efficiency heat exchanger. Regenerative thermal oxizizer pc to 102 figure c 4c.
