‘Deven Supercriticals Pvt. Ltd.’ is innovation driven company dedicated to state of the art Supercritical Fluid (SCF) technology, leading for more than 2 decades. We excel in Pilot to Commercial scale plants, turnkey projects for SCF applications like: Sustainable Textile dyeing; Extraction of Natural products like spices, herbs, fragrances; Sustainable Leather processing; Micronization; Precision cleaning; Sterilization etc. We have supplied 26 SCF plants, including exports to Hungary, Sri Lanka, Malaysia, Pakistan. We are part of global initiative like ‘Fashion for Good’ making fashion more sustainable & greener for the planet. Our innovations are granted with international patents on various aspects of SCF Technology: 1) “Process for Dyeing of Textile Materials using Supercritical Fluid": 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. 2) “System for Continuous Feeding & Discharging of Solid Material to & from a Vessel Operating under High Pressure”: makes SCF Extraction 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. 3) “A Control Valve having a Hollow Piston for Controlling Flow of Fluid”: 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.
