# CCDC — Industrial VOC Recovery Systems in India

> CCDC (Commercial, Chemical And Development Company), Chennai, India, designs and builds industrial VOC (volatile organic compound) and solvent recovery systems for Indian plants. Its systems use Genosorb®, a liquid absorbent made by Clariant, to capture solvent vapour from process vents and return it to production as reusable liquid — 95–99.9% recovery — instead of destroying it in a thermal oxidiser.

Key facts:

- Company: CCDC — Commercial, Chemical And Development Company, Chennai, India; 45 years of process engineering experience. Headed by Dr D M Mohunta, a chemical engineer with about five decades of experience.
- Technology: Genosorb® physical absorption (polyethylene glycol ethers by Clariant A.G.). Continuous absorb → strip → condense → recycle loop at ambient temperature. CCDC engineers the plants; it does not make the absorbent.
- Performance: designed for 95–99.9% recovery; >99% achieved on acrylonitrile and methylene dichloride; 100 Nm³/hr to 100,000+ Nm³/hr; mixtures of up to six solvents; a carbon disulphide plant scaled up 500× from pilot.
- Cost (2004 Indian study, Dr D M Mohunta): acetone recovery cost ₹2.27/kg by absorption vs ₹5.70 by refrigeration and ₹7.47 by activated-carbon adsorption.
- Industries: pharmaceuticals and APIs, chemicals, flexible packaging and gravure printing, paints and coatings, petrochemicals, adhesives, automotive, battery and semiconductor manufacturing.
- Coverage: plants anywhere in India; every system designed, engineered and fabricated in India and delivered skid-mounted.
- Scope: vapour/vent-gas recovery (solvent evaporated into air or nitrogen) — not distillation of spent liquid solvent.

- [Industrial VOC recovery systems in India](https://www.vocrecovery.in): CCDC designs industrial VOC recovery systems in India using Genosorb® absorption: 95–99.9% of the solvent in process vents recovered and reused, for pharma, chemical, packaging and printing plants.
- [Request a feasibility study](https://www.vocrecovery.in/voc-recovery-genosorb-feasibility-study): Request an engineering assessment of your VOC stream. Share solvent, flow, concentration and operating data — or ask CCDC to measure your vent losses — for a preliminary recovery evaluation.

## Technology

- [How It Works](https://www.vocrecovery.in/voc-recovery-genosorb-process): How Genosorb® absorption VOC recovery works step by step — absorber, stripper, condenser and absorbent recycle — and how CCDC engineers each system around the solvent stream.
- [Technologies Compared](https://www.vocrecovery.in/voc-recovery-genosorb-vs-thermal-oxidation): Compare absorption, activated-carbon adsorption, refrigeration and thermal oxidation for VOC recovery, with operating costs in ₹/kg from Indian case studies.
- [Solvent Recovery from Vent Gas](https://www.vocrecovery.in/voc-recovery-genosorb-solvent): How Genosorb® absorbents recover solvent vapour from process vents and dryers — not distillation of spent liquid solvent — with absorbent properties, grades and built-in dehydration.
- [Low-Concentration Streams](https://www.vocrecovery.in/voc-recovery-genosorb-rotary-concentrator): Recover solvent from dilute, high-volume vents (10,000–200,000 m³/hr at a few hundred ppm): a rotary concentrator raises VOC concentration up to 30× and cuts equipment cost 75–85%.
- [Centralised Systems](https://www.vocrecovery.in/voc-recovery-genosorb-system-integration): One VOC recovery unit for multiple emission sources — reactors, dryers, printing and coating lines — with lower capital cost, automatic operation and simpler upkeep.
- [Benefits & Payback](https://www.vocrecovery.in/voc-recovery-genosorb-benefits): The economic and environmental benefits of VOC recovery: solvent returned to production, lower operating cost than oxidation, ~1.3 kg CO₂-eq avoided per kg recovered, and circular-economy and ESG gains.

## Applications

- [Acetone Recovery](https://www.vocrecovery.in/acetone-recovery-unit): Recover acetone from dryer, reactor and process vents with Genosorb® absorption. Why acetone is hard on activated carbon, how the unit works, and an Indian cost study: ₹2.27/kg vs ₹7.47/kg.
- [Pharmaceutical Plants](https://www.vocrecovery.in/pharmaceutical-solvent-recovery): How Genosorb® absorption recovers solvent vapour from API and bulk-drug plant vents — reactors, centrifuges, dryers and tanks — and helps plants meet CPCB's draft 95% solvent-recovery guideline.
- [Flexible Packaging & Printing](https://www.vocrecovery.in/flexible-packaging-solvent-recovery): Recover ethyl acetate, toluene, IPA and other ink and laminating solvents from rotogravure printing and laminating lines with a rotary concentrator and Genosorb® absorption.
- [Effluent COD Reduction](https://www.vocrecovery.in/voc-recovery-genosorb-effluent-cod-reduction): Cut the COD of solvent-laden effluent by over 99%: solvents are air-stripped from the water, concentrated and recovered with a Genosorb® plant.
