Solvent Clean

These days, with atmospheric pollution becoming a problem of global proportions, emission regulation of VOC(1) is being strengthened and interest in VOC processing technologies is increasing. Up till now, when processing exhaust gases in large air volumes containing low concentrations of VOC, large-scale equipment has been required, greatly increasing both initial and running costs.

By using SOLVENTCLEAN, exhaust gases in large air volumes containing low concentrations of VOC, which have caused difficulties in the past, can be concentrated into low air volumes with high concentrations and, by combin- ing SOLVENTCLEAN with existing (oxidization method, recovery method, etc.) processing equipmentes, efficient processing of exhaust gases containing VOC has become possible.

 Note(1) VOC : volatile organic compound

BASIC SYSTEM 

FEATURE

ZEOLITE SELECT FOR TYPICAL VOC

EXAMPLE SYSTEM 

High Temperature desorption system

■    Features
A system that periodically conducts a “300°C desorption operation (high temperature desorption operation)” to desorb accumulat- ed high boiling point substances and prolong the life of the rotor. The 300°C compatible sealing material is a mechanism that is unique to Nichias.
■    Usage results
Purposes : Semiconductor and liquid crystal panel production line exhaust gases, photogravure print drying exhaust gases, chemical production line exhaust gases, etc.
