Nitrogen compound countermeasure catalytic deodorization device

This system is an apparatus that decomposes organic nitrogen (such as amines, DMF, NMP, etc.) into nitrogen, carbon dioxide, and water vapor, using a combination of organic nitrogen decomposition catalysts and oxidation catalysts, as shown in the figure on the right, while keeping the generation of NOx and N2O low, replacing the conventional system that consisted of primary oxidation catalysts, reduction catalysts, and secondary oxidation catalysts.

Set of 3 product and technical documents for catalytic deodorization devices (VOC treatment devices).

Introducing the features of the catalytic deodorization device all at once! Lower initial cost than thermal storage type, and lower running cost than direct combustion type!

In recent years, heat storage deodorization devices have become popular, but do they really meet production needs? When it comes to deodorization devices, there are various treatment methods available. Among them, more companies are choosing the "catalytic type," which has the highest purification rate in combustion methods, with operating costs less than half compared to direct combustion, and is also low in installation costs and has a shorter lead time than heat storage types, making it suitable for various locations. As fuel costs rise, the advantages of catalytic deodorization devices, which can reduce fuel consumption and maintenance costs, are becoming increasingly prominent. Compared to heat storage types, these devices are smaller and have a quicker startup time, making them ideal for production lines that do not operate 24 hours, test plants, and research and development use. Therefore, we are offering a set of three documents that explain the features of catalytic deodorization devices! Please take a look at them as reference materials for your introduction considerations. Additionally, feel free to consult us regarding VOC measures or any odor-related issues. 【Overview of the 3-Book Set】 ■ Comprehensive Product Catalog (Includes our deodorization devices from heat storage to catalytic types) ■ Basic Knowledge for Introducing VOC Treatment Devices (Includes information on emission regulations and how to choose devices) ■ Comparison Table of Deodorization Methods (Comparison with combustion, plasma, adsorption, etc.) *You can view them immediately from "Download." Please feel free to contact us.

Environmental Equipment: NOx Countermeasure Catalytic Deodorization Device

This is a device that processes exhaust gases containing organic nitrogen (amines, DMF, NMP, etc.) while keeping the generation of nitrogen oxides (NOx, N2O) low.

TESSHA Corporation's NOx control catalytic deodorization device is designed to treat exhaust gases containing organic nitrogen (such as Mian, DMF, NMP, etc.) while keeping the generation of nitrogen oxides (NOx, N2O) low. It decomposes organic nitrogen in the exhaust gases into nitrogen, carbon dioxide, and water vapor using organic nitrogen compound decomposition catalysts and oxidation catalysts. =========================== You can view the "Quotation Request Form" from the "Download" section. Please fill in the various conditions and send it by FAX, and we will calculate it for you. =========================== For more details, please contact us or download the catalog.
