Regenerative Thermal Oxidizer Process Flow Diagram

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.

Regenerative thermal oxidizer process flow diagram.

Inlet switch valves direct the pollutant laden air into one of the energy recovery canisters. Co 2 is 25 times less potent than methane when emitted into the atmosphere with regards to global warming. About rtos regenerative thermal oxidizers summary. Table 2 1 provides capital cost estimates for thermal oxidizers in several industry source categories.

A regenerative thermal oxidizer or rto builds on the thermal oxidation operating principles but at greatly enhanced fuel efficiency. One of the most efficient technologies to a. 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. An rto consists of two or more heat.

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. Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated. The process begins with a high pressure supply fan that forces exhaust fumes into the regenerative thermal oxidizer.

An rto burns very lean waste gases without using much fuel. Flaring is a. Methane is a greenhouse gas and when oxidized via thermal combustion is chemically altered to form co 2 and h 2 o. Concentrations of methane in mine ventilation.
