Keeping with the idea that chemical industries can be environment friendly and yet be able to deliver profitability through process innovation and optimum resource utilisation, CCDC advocates the recovery of solvents.
High to Medium Concentration Solvent Vapor Recovery:
CCDC can offer a variety of solvent recovery solution's; such as distillation, extraction and refrigeration (partnering with Edwards Engineering Corp., NJ, USA) for high concentration solvent vapor streams.
Low Concentration Solvent Vapor Recovery:
This method was developed by CCDC (with technical input from Clariant, Germany) for vapor streams having concentration of less than 10%. In ususal methods (including carbon bed adsorbtion), recovering solvents from such low concentration streams are virtually impossible without them being economically unviable.
CCDC, has developed a method using abosrbtion principles for such low concentration vapor recovery, where recovery of solvent can be designed from 95% to 99.9%.The economics of such a technology is dependent on the vapor stream composition as well desired percentage recovery.
