The "VOC catalytic deodorization device" contributes to VOC countermeasures in response to VOC emission control regulations, reduces equipment costs and running costs, and enables more efficient VOC treatment. It oxidizes and decomposes VOCs (volatile organic compounds) generated from manufacturing lines in industries such as chemicals, food, pharmaceuticals, and printing into CO2 and H2O, eliminating odor generation. By using a catalyst, the oxidation and decomposition temperature can be maintained between 150 and 350°C, significantly reducing energy consumption compared to direct combustion methods. Additionally, by using an economizer (heat exchanger), heat recovery is possible, allowing for further energy recovery. 【Features】 - Operating at low temperatures (150-350°C) for contact oxidation results in lower running costs compared to direct combustion methods. - The device is more compact compared to other methods. - The catalyst can be cleaned and regenerated. *For more details, please download the PDF or feel free to contact us.

The "Stripping Tower / Absorption Tower" is an ammonia treatment facility designed to separate and recover ammonia from wastewater containing ammonia (including salts). Operation is fully controlled by an automatic sequence, with complete unmanned operation except for the button operation to stop the system. The lower part of the absorption tower functions as a barometric condenser, circulating and cooling the absorbed ammonia water, and concentrating the ammonia/water vapor that exits from the top of the stripping tower. Additionally, by performing a reflux from the absorption tower to the stripping tower, it is possible to recover ammonia at any desired concentration up to 35 wt%. 【Features】 ■ Reaction Section - Reacts ammonium chloride with caustic soda to release ammonia. ■ Discharge Section - Supplies the wastewater reacted in the reaction section to the stripping tower. - By introducing steam from the bottom of the stripping tower, ammonia/water vapor is extracted from the top of the tower, and treated water containing NaCl is extracted from the bottom of the tower. *For more details, please download the PDF or feel free to contact us.

The "Stripping Tower/Catalytic Deodorization Device" is a system that oxidatively decomposes ammonia vapor emitted from the stripping tower using an ammonia decomposition catalyst, rendering it harmless. This catalyst oxidizes unpleasant odors and harmful substances generated in fields such as printing, chemicals, resin processing, and painting. Compared to direct combustion methods, it consumes less fuel, allowing for a reduction in running costs. With the introduction of this device, there are cases where industrial waste processing has been eliminated, leading to a reduction in industrial waste processing costs. 【Features】 ■ Capable of responding to load fluctuations from low to high concentrations ■ Treats wastewater for industrial waste processing ■ Capable of automatic operation *For more details, please download the PDF or feel free to contact us.

The "ammonia catalytic deodorization device" is a system that oxidatively decomposes ammonia gas emitted from stripping towers and production processes using an ammonia decomposition catalyst, rendering it harmless. By containing ammonia and neutralizing waste gas, it has achieved low NOX combustion, eliminating concerns about air pollution. Nitrogen compounds like ammonia (such as amines) can also be oxidized and neutralized using the ammonia decomposition catalyst. Additionally, ammonia gas emitted from a certain company's production process could only be disposed of as waste and could not be released as is; however, with the introduction of this device, it has become possible to combust and neutralize it for release. 【Features】 - Operates at a low temperature of 240-250°C for contact oxidation, suppressing the generation of nitrogen oxides (NOX) from combustion. - The device is more compact compared to other methods. - The catalyst can be cleaned and regenerated. *For more details, please download the PDF or feel free to contact us.*

This document contains information about "evaporation concentration equipment." Evaporation and concentration are operations that involve boiling off moisture from a solution to obtain a more concentrated solution, and they have been used for a long time in various fields such as chemicals, food, and paper pulp. When designing evaporation concentration equipment, it is important to consider the physical properties of the target substance and the processing capacity, and to select the appropriate type.
