Regenerative Thermal Oxidizer Process Flow Diagram

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.

Regenerative thermal oxidizer process flow diagram.

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. 1 incinerators should not be confused with flares. Regenerative thermal oxidizer rto a regenerative thermal oxidizer also known as an rto is a type of air pollution control equipment designed to decompose volatile organic compounds vocs hazardous air pollutants haps and other airborne solvents into innocuous co 2 and water vapor by heating the exhaust air to a very high temperature over 1400 f. Ventilation air methane thermal oxidizers are used to destroy methane in the exhaust air of underground coal mine shafts.

Flaring is a. Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016. Regenerative thermal oxizizer pc to 102 figure c 4c. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated.

An rto consists of two or more heat. This voc abatement technology utilizes ceramic media packed into vertical canisters as a high efficiency heat exchanger. Inlet switch valves direct the pollutant laden air into one of the energy recovery canisters. A regenerative thermal oxidizer or rto builds on the thermal oxidation operating principles but at greatly enhanced fuel efficiency.

Table 2 1 provides capital cost estimates for thermal oxidizers in several industry source categories. One of the most efficient technologies to a. 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. About rtos regenerative thermal oxidizers summary.

An rto burns very lean waste gases without using much fuel. Concentrations of methane in mine ventilation. Methane is a greenhouse gas and when oxidized via thermal combustion is chemically altered to form co 2 and h 2 o. Co 2 is 25 times less potent than methane when emitted into the atmosphere with regards to global warming.
