Regenerative Thermal Oxidizer Process Flow Diagram
This voc abatement technology utilizes ceramic media packed into vertical canisters as a high efficiency heat exchanger.
Regenerative thermal oxidizer process flow diagram. Regenerative thermal oxidizers destroy volatile organic compounds vocs and hazardous air pollutants haps that are created through chemical processes and industrial exhaust steams this type of oxidizer uses extremely high heat about 1500 f to clean the exhaust of dangerous pollutants and compounds. An rto burns very lean waste gases without using much fuel. One of the most efficient technologies to a. Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016.
The simplest technology of thermal oxidation is direct fired thermal oxidizer. Table 2 1 provides capital cost estimates for thermal oxidizers in several industry source categories. About rtos regenerative thermal oxidizers summary. The process begins with a high pressure supply fan that forces exhaust fumes into the regenerative thermal oxidizer.
A process stream with hazardous gases is introduced into a firing box through or near the burner and enough residence time is provided to get the desired destruction removal efficiency dre of the vocs. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated. 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. Inlet switch valves direct the pollutant laden air into one of the energy recovery canisters.
What are regenerative thermal oxidizers. 1 incinerators should not be confused with flares. 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.
