Patent granted
Our innovations are granted with international patents on various aspects of SCF Technology:
- "Process for Dyeing of Textile Materials using Supercritical Fluid" (Indian Patent no. 298213, USA Patent No. US 11015289 B2) : an improved, sustainable, single step Dyeing as well as Finishing technology for man-made, natural & blended textiles. Allows use of traditional dyes, improves dye utilization, easy scale-up & less than half dyeing time than prior-art SC CO2 processes. Avoids reduction clearing, two bath dyeing for blends. Much less use of auxiliary chemicals, No salt, reducing the water, energy load resulting in minimum environmental impact.
- "System for Continuous Feeding & Discharging of Solid Material to & from a Vessel Operating under High Pressure" (USA Patent no. US 10328406 B2, European Patent no. EP 3242741 B1): Innovative system for making SCF Extraction from batch into continuous process to (i) reduce loss of Solvent during depressurization of Extractors between batches (ii) minimizes non-productive time of De-pressurization, Feed Change & Re-pressurization (iii) Avoids loss of extraction efficiency due to depletion of the effective height of feed bed in batch process.
- "A Control Valve having a Hollow Piston for Controlling Flow of Fluid" (USA Patent no. US 10883612 B2): Innovative design of control valve suitable for high pressure drop & dirty service applications; requiring low force for achieving leak-tight shutoff; also enabling smooth, non-jerky operation over entire stroke length for normal to precision control of fluid flow.
