VOC Recovery Facilities

Based on multiple technologies we have cultivated through construction of VOC recovery facilities, we are able to propose a system meeting the gas volume and VOC concentration.

In order to recover expensive solvent for reuse under compliance with the PRTR Act and the Air Pollution Control Act, our system condenses and recovers exhaust gases containing volatile organic compounds (VOC) that are released into the air.

Features

Compared to other methods such as the cryogenic method or the condensation method, our system can achieve high removal and recovery rates at a low running cost.

With our various skills and technologies, we are able to propose the best system according to your specific requirements.

Benefits

Recovery and reuse of VOC as liquid results in cost savings.

Major Application

VOC recovery

Specifications

Applicable scope: Exhaust gas volume: - 1,000,000 m3/hr; VOC concentration: - 500,000 ppmv

Processes and Methods

CAD-VRU1, CAD-VRU2, and CAD-VRU LL

Combustion treatment usually requires fuels for combustion; however, our system can produce a cost advantage immediately after introduction by reusing recovered liquid.

【CAD-VRU LL】

Licensed by CMI Environment America、Inc. of the United States.

Adsorbs and separates VOC from VOC-containing exhaust gas, and recovers VOC as a solvent.


・Appropriate for the treatment of VOC-containing exhaust gases of middle to low concentration with a small to large amount of air volume.

・Recovery solvent can be reused.

・The amount of steam can be reduced by 40% by introducing this unique energy-saving system.

CMI Environment America、Inc.

(2525 Cabot Drive Suite205 Lisle, Il USA)

CMI Environment America、Inc. is a U.S. engineering firm with a small number of selected elite engineers, which was derived from a major French active carbon manufacturer, CECA (currently in the ARKEMA Group). AMCEC INC. has specialized in adsorption and recovery systems for VOC (solvents) contained in the gas phase and liquid phase by using active carbon and zeolite. This firm has valuable know-how, having delivered their systems to more than 1000 facilities for about 80 years including the times of its predecessor, CECA.
