Koole Terminals: an example of what we can do for you
Koole Tankstore Minerals is an international hydrocarbon storage company with a total storage capacity of over 3,500,000 cubic metres. Tecam was contracted to reduce Volatile Organic Compound (VOC) emissions generated during gas venting at Koole’s facilities in the port of Rotterdam in The Netherlands.
We proposed a custom-made solution based on Regenerative Thermal Oxidizer (RTO) technology, which achieved 99.9 % reduction in the company’s VOC emissions.
Learn more about this success story, which made Tecam winner of the Tank Storage Award in 2020 in the category of “Environmental Performance”.
Satisfied customers that have placed their trust in us. Heceygo
“We are very happy to have Tecam as our provider of environmental technology solutions. They install the latest technology and only use high-quality components from leading brands in their Regenerative Thermal Oxidizer (RTO) systems for the treatment of Volatile Organic Compounds (VOCs). We value their flexibility – which enables them to meet our technical needs – very highly, along with their rapid response and excellent maintenance service.
Tecam is a partner you can trust when it comes to reducing the emission of Volatile Organic Compounds (VOCs) at a production plant. In our case, we have significantly reduced our emissions, and the equipment they installed has worked perfectly since 2008″.

What is an RTO?
Regenerative Thermal Oxidizer (RTO) is a piece of equipment designed to eliminate Volatile Organic Compounds (VOCs). Essentially, it is formed of three towers with ceramic beds, where energy is recovered, and a combustion chamber in which the temperature is kept constant in order to enable oxidation. The organic compounds it eliminates consist primarily of carbon and hydrogen: consequently, when they react with oxygen they form carbon dioxide and water. The combustion chamber incorporates a burner that normally uses natural gas to raise the temperature inside the chamber, although other fuels (fuel oil, diesel oil, etc.) can also be used.
How an RTO works
In a Regenerative Thermal Oxidizer (RTO) system, the contaminated air to be treated is sucked in by the main fan, which is usually located upstream of the oxidiser, although for processes with high concentrations of suspended particles the fan is usually located downstream of the oxidiser.
The fan then pushes the air to be treated through the first ceramic tower. In this first tower, the air is heated along with the ceramic media. When the air has passed through the ceramic bed, it reaches the combustion chamber, where the oxidation takes place. For gases without halogenated compounds, the temperature is usually around 800 ºC – 900 ºC; however, for gases that contain halogenated compounds, the temperature needs to be around 1100 ºC in order to ensure full oxidation. In each instance, the temperature will depend on the compounds that are to be treated.
At the same time, as air to be treated enters the first chamber, the now-oxidised air is passed through the second ceramic tower, in order to transfer its heat to the ceramic media. This cools the gas and heats the ceramic bed. After passing through the second tower, the air – now free from pollutants – is sent up the flue.
The third ceramic tower is used to recirculate the purged elements, as all of the air must be oxidised during the valve sequencing.
The sequencing procedure is repeated periodically, every 45-90 seconds, in order to make sure each tower is operating in the same way.
Systems with three ceramic towers are the most common, although you can find Regenerative Thermal Oxidizers with two towers and even some that have five towers.
Take advantage of the benefits of installing an RTO
The advantages of installing a Regenerative Thermal Oxidizer (RTO) lie in the ability to optimise your energy use while maintaining the same level of efficiency for eliminating VOCs. This is due to the fact that the ceramic towers are able to store a large amount of energy during each sequence, which in turn serves to heat the air or gas that is being treated. In fact, thermal efficiency can reach levels of 90-95 %.
This means that under normal operating conditions, fuel gas is not consumed, as the process is autothermal. An autothermal process is one in which the oxidation chamber maintains its operating temperature without needing to burn energy from an external source (i.e. fuel). This is because the energy released by the VOCs as they oxidise is sufficient to keep the chamber at a high temperature.
The ideal solution for treating the VOCs in gaseous emissions, suitable for almost every industrial sector
A Regenerative Thermal Oxidizer (RTO) system can be installed in a wide variety of industrial applications, including the chemical, pharmaceutical and petrochemical sectors, storage tank facilities, the oil and gas, paint, coatings and construction industries, and many other sectors where VOCs are an issue.
