Regenerative thermal oxidation RTO

A regenerative thermal oxidation equipment, also known as a THERMOREACTOR, removes volatile organic compounds (VOCs) from gases by thermal oxidation. This thermal oxidation is achieved by raising the temperature of the gases enough for these organic compounds to oxidize, combining with oxygen to form CO2 and water.

This type of thermal oxidation is characterized by a device, called regenerator, that recovers the heat of the purified gases. These regenerators are elements made of ceramic material that have the ability of accumulating the heat of the gases that leave the oxidation chamber.

Through a system of valves, consecutive operating cycles are established by which the purified gases, which are at an elevated temperature (about 800 ºC), yield their heat to the ceramic masses so that the contaminated gases, which enter the facility cold, take from them in the next cycle.

CHARACTERISTICS

  • Minimum fuel consumption, since it allows very high heat recovery efficiencies
  • High purification efficiency
  • Very low operating and maintenance costs
  • Long duration of the equipment
  • Great reliability, for being highly tested equipment

Zeolite rotorconcentrator

When the flow of gases to be cleaned is high and the concentration of organic compounds is very low (less than 1 g/Nm³), the treatment by thermal oxidation would suppose a very high energy cost, since the heat generated by the organic compounds would be very low and the heat to get the oxidation temperature should be achieved by the burner. Therefore, in these cases, organic compounds are concentrated in a gas stream with a volume between 10 and 16 times lower that will be later treated.

This concentration of the gases to be purified is achieved by a zeolite rotor concentrator, which is a device capable of adsorbing on its surface the organic compounds of the gas stream to be purified. The zeolite absorber is impregnated on a corrugated mineral fiber substrate within the rotor.
The gases to be cleaned, with a low concentration of VOC's, pass through a filter in which the particles are retained. Once filtered, the gases pass through the rotor in which the VOC's are absorbed. The clean gases leave the wheel and are emitted into the atmosphere through a chimney.

The VOC's are desorbed from the rotor by the passage of a small stream of hot gases in the opposite direction to that of the process gases. The rotor cools this gas stream as the VOC's desorb and exit as a concentrate at a temperature of 50 to 60° C. Normally, the further treatment of the concentrate consists of thermal oxidation (usually in a thermoreactor).

The process gases that leave the cooling sector of the rotor are hot (at a temperature between 75 and 110 °C) and can be used as desorption air with additional heating. The use of this air preheated by the rotor in the cooling zone reduces the overall energy consumption of the system.

 

 

Recuperative thermal oxidation

CIt consists of the same chemical process occurring in the regenerative thermal oxidation, with the difference that the heat of the exhaust air is used for other industrial thermal processes at the customer's request.

These conditions are achieved inside an oxidation chamber designed for this purpose and that is equipped with a conical air vein burner that uses the gas to be purified as combustion air. This way, the energy necessary for the purification process is reduced to the maximum.

As in the case of regenerative thermal oxidation, this technique is used to eliminate both organic (solvents, odors ...) and inorganic compounds (CO, SH2, NH3 ...). It is frequently used in situations where the gas flow is small but the concentration of pollutant is relatively high (up to 20 g / Nm³ of total organic carbon).

If the concentration of organic pollutants is high, these facilities are convenient because they allow the oxidation heat of the contaminants to be used in the industrial process.

Each recuperative installation is custom designed to adapt it as much as possible to the client's process

The main features of these equipment are:

  • High efficiency.
  • Relative flexibility in terms of flow variations (from 1 to 3).
  • Possibility of energy recovery of gaseous waste.
  • High energy cost of operation if the pollutant concentrations are low.

Wastewater disposal

The wastewater disposal by thermal oxidation consists in causing its combustion and keeping the gases generated at a sufficiently high temperature for the time necessary to get the reaction completed. These conditions are achieved inside an oxidation chamber properly designed to get a good mixture and a sufficient process time. This way, the organic compounds are completely transformed into CO2 and water.

The advantages of the systems of wastewater disposal by thermal oxidation are:

  • The liquids are eliminated in a complete and clean way.
  • The heat released in combustion can and must be used, thus achieving the energy recovery of the waste.
  • Non-combustible liquids can also be purified, like water contaminated with organic matter. In this case, it may be necessary to provide additional fuel.
  • The flame temperatures are low, so low levels of nitrogen oxide emission are achieved.

Biogas torch

BLUETOR,is a biogas torch system ideal for the disposal of biogas from landfills and for any other type of organic pollutant emission in the industry, complying with the most demanding environmental regulations.

PRINCIPLE OF OPERATION

The biogas to be thermally oxidized is introduced through a blower through the WIDE RANGE®, combustion system, achieving a perfect mix with the oxidation air. The optimal temperature for the oxidation of biogas is achieved by combining combustion with a dilution system controlled by PLC. The WIDE RANGE® pilot guarantees the lighting of the torch in all circumstances. .
