Abstract
This study shows the evaluation and consulting for pollution prevention of dye production by cleaner production methodology. Especially, this study intended to investigate the methods for reduction of process water and recovery of organic solvent (DMF), and to modify the process for higher qualified products in the acid dye production by cleaner production methodology. This methodology, consisting of 7 sequential phases (business leadership decision to start, problem definition, evaluation of the screened options, option selection for implementation, implementation, monitoring and sustainable implementation), is based on initial developments in the USA and Western Europe. Reduction of process water over 25%, recovery of DMF and solubility enhancement of acid dye over 2 times were achieved.
청정생산방법론을 적용하여 염료생산공정의 청정화를 꾀하고자 하였다. 본 고에서는 반응중에 사용되는 공정수와 유기용매인 DMF의 회수방안을 모색하고, 고급산성염료 제조공정 보완을 통한 제품질 향상 방안을 마련하고자 하였다. 청정생산방법론의 적용순서는 기업경영진의 결정, 대안도출, 대안평가 및 우선순위 결정, 실행, 모니터링 및 지속적 실행단계의 절차를 따라 수행하였으며, 이의 수행결과 DMF의 회수와 함께 용수사용량을 25% 이상 절감할 수 있었으며, 고급산성염료의 경우 2배 이상의 용해도 향상을 통하여 제품의 가치를 상승시킬 수 있었다.
