Process Modification in Dye and Dye Intermediates – Acid Dyes

‘Process Modification’ refers to the development of radical technologies for the miniaturization of process plants while achieving the same production objective as in bulky conventional processes. The goal is to bring down the plant size by 10-1000 times by replacing large, expensive and energy-intensive equipment or processes with ones that are smaller, less costly and more efficient. Hybridization of multiple unit operations and processes into a single compact device is the rule of thumb for process intensification.

The objective of the paper is to Modify, Intensify and Energy Efficient process in dye manufacturing units in Gujarat. The focus of the study is to minimize wastes, to improve energy efficiency and improve the process practices/cycles to optimize resource utilization.
