[Construction Case] Reuse through Liquefaction Recovery - VOC Recovery Device

Reuse exhaust gas by converting it into liquid!

【Service Overview】 An adsorption device that reduces low flow, high concentration exhaust gas, which continuously emerges from chemical plant process equipment, to below 100 ppm through activated carbon adsorption. 【Customer's Challenges and Background】 In a process where VOCs are continuously generated, the cost and usage of solvents were increasing. The customer was considering a method to recover VOCs generated from the production process in as high a purity state as possible for reuse. 【Solution】 We collaborated with SES to identify lines where high concentration gas was generated locally in the production process. By controlling the treatment gas flow rate and making the device more compact, we were able to install an efficient recovery device without waste. 【Results and Effects】 As a result, we were able to maintain the design outlet concentration below 100 ppm. The recovered solvent is automatically transferred when liquid accumulates, reducing operational burden and creating a system for reuse. By recovering it as a solvent, this also contributes to the reduction of exhaust gas, leading to compliance with regulations and improvement of the internal work environment.
