초록

본 연구에서는 염화 제 철 수용액의 재생 공정에 주로 쓰이고 있는 철환원법을 대체하기 위한 방법으로 액-액 용매 추출법을 사용하여 수용액 내에 잔존해 있는 중금속인 Fe와 Ni 을 분리 회수하는 공정을 개발하였다. Lab 실험을 통해 우선 염화 제 철 수용액으로부터 선택적으로 염화 제 철만을 추출할 수 있는 용매조건을 개발하였고, 그 결과를 사용하여 액 액 추출공정의 상업화 추진을 위한 pilot 공정 및 장치를 개발하였다. 또한 pilot test를 통하여 추출단과 역추출단의 단수를 결정할 수 있었고, 양산 공정에 적용할 수 있는 공정 데이터를 확보하였다.

A liquid-liquid solvent extraction process was developed in this study to recover Fe and Ni from heavily concentrated aqueous ferric chloride solution, in an effort to substitute the conventional iron reduction method. Solvent composition and extraction conditions were first developed from the laboratory experiments, and the pilot system was designed and built for commercialization. Stage numbers for extraction and stripping were determined from pilot plant runs, and other operation data were obtained for mass production.
