Catalytic reactor

Catalytic gas emissions abatement systems are modular.
Basic configuration consists of the following modules:

Heating module.Heats up gas flow to the temperature , necessary for steady catalytic process.
Catalytic reactor.Designed for organic and non-organic emissions abatement.
Recuperative module.Designed for nonpurified air preheating and cleaned gas cooling газа by means of recuperation of heat.

Catalytic gas emissions abatement systems are equipped with optional modules when necessary:

Filtration module.It ensures cleaning of solid particles (dust, resin) and aerosols.
Sorption module.It provides cleaning of acid gases, halogen-,sulfur-, phosphorous compounds and prevents accumulation of dirt.
Optional systems.Urea injection system (in cases of high NOx content), air flow control system, monitoring system (pressure drop, temperature and concentration measurement).

Как происходит очистка газовых выбросов?

Очищаемая газовоздушная смесь (ГВС), поступающая от источника выбросов, последовательно проходит через модули теплообмена и нагрева. Прогретая до температуры 400-450°С, необходимой для начала протекания каталитического процесса, ГВС направляется в модуль катализа, в котором происходит реакция разложения загрязняющих веществ.

Далее нагретая и очищенная ГВС охлаждается в теплообменном модуле, отдавая свое тепло поступающему в установку выбросу от источника. Работа установки происходит в условиях разрежения, создаваемого вытяжным радиальным вентилятором.

Система автоматического управления контролирует процесс работы УТК, получая данные с термопар и передавая сигналы в модуль нагрева и на вытяжной вентилятор. При необходимости система автоматического управления УТК может передавать параметры работы УТК в систему верхнего уровня посредством универсального протокола связи Modbus.

Regenerative thermal oxidation system

Today regenerative thermal oxidation system is the most efficient abatement solution for VOC process and ventilation in chemical and pharmaceutical industries. Industrial air cleaning by means of RTO system is an economically feasible option for printing plants and paint manufacturers.

High energy efficiency is one of the main advantages of RTO systems. Exhaust gas temperature can be used for air heating in production premises or water or oil heating.

Regenerative thermal oxidation system advantages:

Versatility.Regenerative thermal oxidation system can be used for both low and high concentrations of VOC ranging from 1000 to 150 000 m3/h.
Zero-waste operation.RTO system ensures complete VOC decomposition therefore there is no need in designing and implementing a waste management system.
Reliability.RTO consists of towers with heat resistant ceramic insulation. Long service life of ceramic material guarantees continuous operation of the system.

Chemisorption module

Сhemisorption module is specifically developed for sulfur odor, halogen-containing extractives, hydrogen sulphide and ammonia neutralization.

It can be used both as a part of gas emissions abatement system or as an individual unit of equipment in air ventilation system.

Chemisorption module advantages:

Efficiency. Emission abatement efficiency can reach up to 99,8% depending on the amount of sorbent and emission composition.
Versatility. Operating temperature ranges from -30 to +450, making it possible to neutralize emissions from a variety of processes.
Multifunctionality. Сhemisorption module can be used both for regular day to day abatement and neutralization of emergency emissions.


The system is intended for air sterilization and air purification from dust, aerosols and gases in a broad range of volumes and concentrations.

The scrubbers can be installed in the local exhaust ventilation, local exhaust systems, waste gas lines, air purification and recirculation systems.

The principle of the system is based on the neutralization of residual concentrations of pollutants by dint of chemical solution continuously circulating in the scrubber.

The continuity of a cycle with unchanged characteristics is not limited.

Scrubber advantages:

Economy. Scrubber has low operating costs.
Simplicity. Service is limited to exterior check.
Reliability. Service life up to 50 years: system is made of plastic of plastic — a material with minimal adhesion.

Thermal utilization system

The thermal utilization system is used for cleaning of large volumes of emissions from harmful substances of acid gases.

The system is based on the process of high-temperature oxidation of most volatile organic components (VOCs) and sulfides.

The system allows to achieve abatement efficiency of up to 98% and to obtain safety components — carbon dioxide and water.

The thermal utilization system advantages:

Easy servicing. A reliable automatic control system that does not require the constant presence of staff.
Modularity. The infrastructure of the system can reduce the amount of installation work and facilitate the service operation.
Reliability. The system fully meets the requirements of fire-explosion safety.
