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 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. One of the most efficient technologies to a. 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. 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. Flaring is a. 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.

Concentrations of methane in mine ventilation. A regenerative thermal oxidizer or rto builds on the thermal oxidation operating principles but at greatly enhanced fuel efficiency. Regenerative thermal oxizizer pc to 102 figure c 4c. 1 incinerators should not be confused with flares.

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. Industrial manufacturing and other processes often produce volatile organic compounds vocs that must be abated. About rtos regenerative thermal oxidizers summary. An rto consists of two or more heat.

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. Polyethylene plant c process flow diagram product feeds vent streams recycle feeds waste feeds oxidizer feeds fuel burning equipment pm pollution control devices comonomer liquid waste waste waxes pellet handling pc pe 205 recycled gas transported to cracker degassing transportation pc pe. Historically the most commonly used is the regenerative thermal oxidizer rto although recuperative thermal oxidizers are becoming more common icac 2016.
