Thermal Catalysis (Catalytic Gas Emissions Neutralization System)

Application

The system is designed for purification of air and gas emissions of pollutants from a wide range of concentrations and volumes. It can be mounted in the local foul air system, local exhausts, waste lines, gas purification systems and air recycling facilities.

Tasks

• Cleaning of gas emissions from most pollutants, including a pair of aerosols and organic and inorganic compounds (including CO, NH3, NOx);
• Air cleaning from paint and solid aerosols;
• Purification of gas and smoke emissions of dioxins, benzpyrene and furans;
• Replacement and upgrading of existing treatment systems.

Efficiency

Cleaning efficiency — 99,9%.

Application Fields

Chemical and oil and gas industry, coke production, metalworking and mechanical engineering, painting chambers, and the paint industry, waste management, industrial facilities and other industries.

Description

Gas emission cleaning is held at flameless decomposition and oxidation to carbon dioxide, water and nitrogen at 300–400 °Ñ on current-heated catalytic blocks (foam material with the catalyst carrier). The system works in automatic programmed mode. Installation can be completed filtration or sorption modules, automatic measuring devices concentration explosion and flame arresters, remote terminal settings on the board instrumentation.

System packaging arrangement

The system is modular and can consist of the following modules:

• Catalytic reactor (core module) is designed to clean emissions from organic and inorganic compounds (except for the halogen — and sulfur-containing compounds).
• Heat-exchanger module (core module) provides pre-heating of the incoming raw gas cooling and cleaned hot gas (heat recovery).
• Filtration module (additional module) ensures cleaning of solid particles (dust, resin) and aerosols.
• Sorption module (additional module) provides cleaning of acid gases, halogen-,sulfur-, phosphorous compounds and the accumulation of dirt.
• Additional systems: urea supplying (high content of nitrogen oxides), flow control, monitoring (measurement of pressure drop, temperature, concentration).

Please note that the system packaging arrangement is determined individually according to the emissions of each customer based on the completed questionnaire. The basic package includes the core modules, additional modules are considered in the presence of a release of pollutants that can be cleaned by them.
