The "VOC-VRU" is a device that collects volatile organic solvent gases from inert gases, thereby increasing the purity of the inert gas and enabling its reuse. The organic solvent gases that can be recovered from the inert gas are the same as those that can be processed by organic solvent gas recovery devices, but this device uses a newly developed adsorbent. Due to its simple process and skid-mounted design, it requires a small footprint and can be constructed at a low cost. 【Features】 ■ Reusable inert gas ■ High recovery rate ■ Compact equipment and low capital investment ■ Dry operation ■ Atmospheric pressure operation *For more details, please refer to the PDF document or feel free to contact us.

"SES-VRU" is a product that uses a special adsorbent for the liquid recovery of VOC vapors generated under various conditions. By changing the adsorbent, the method of filling the adsorbent, and the method of recovering desorbed gas, it is possible to recover a wide variety of VOCs in liquid form. By implementing this system, there are benefits such as compliance with VOC emission regulations and the reuse of recovered VOCs. 【Features】 ■ Simple process ■ High safety ■ High VOC recovery rate ■ Optimization of the adsorption tower ■ Fully automated operation *For more details, please download the PDF or feel free to contact us.

The "Volatile Organic Solvent Gas Recovery Device" is a system developed to recover volatile organic solvent gases and prevent air pollution. It uses non-combustible adsorbents and does not utilize heat sources such as steam, resulting in an extremely low risk of fire, while maintaining high safety even when flammable gases are introduced. Additionally, the simple process and skid-mounted structure minimize the required land area and installation costs. 【Features】 ■ High safety ■ High removal rate ■ Sophisticated equipment configuration ■ Dry operation ■ Low-pressure operation *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of our "Recovery Device (PSA Method)" implemented at a major oil company. The company manufactures petrochemical base products, and as of 2000, the VOC emissions were 820 tons/year. The majority of the VOC emissions were due to the solvent discharge of dichloromethane used in the resin manufacturing process, and in 2002, they introduced our product. Our product uses silica gel as the adsorbent, and the desorption of the adsorbed solvent is performed by vacuum. With two adsorption towers, it alternates between adsorption and desorption, achieving continuous operation and significant reductions. [Reasons for Adoption] - Wide applicable concentration range for the target gas - High removal and recovery rate (over 99%) - No wastewater containing solvents is generated as no steam is used for heating during desorption and regeneration - Using silica gel as the adsorbent helps suppress temperature rise due to adsorption heat - Gradual deterioration, leading to an expected long lifespan *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case study of our "Pressure Swing Adsorption (PSA) Equipment" implemented at a comprehensive chemical manufacturer. The company had previously been using temperature swing adsorption (TSA) equipment with activated carbon to recover and treat exhaust gases containing vinyl chloride monomer. However, due to the high adsorption heat of activated carbon, they had to process a large volume of diluted gas, resulting in large equipment size and significant energy consumption due to the large amount of steam used during desorption. Additionally, they faced issues with equipment corrosion caused by chlorine. While addressing equipment corrosion, they explored alternative systems and determined that our product could be applied to their process, leading to full-scale operation starting in the 2011 fiscal year. They successfully reduced steam consumption by 3,700 tons compared to the previous year and achieved over a 90% reduction in VCM emissions from the adsorption equipment. [Customer Feedback] ■ We were able to introduce a much more compact exhaust gas treatment system with lower environmental impact. *For more details, please refer to the related links or feel free to contact us.
