Abstract

Produced water from oil production processes is mostly composed of oily wastewater. So, it is important to extract and remove the oil components from the produced water environmentally and in utilizing water resources. Produced water treatment is classified as physical, biological and chemical method. The technology trend of oil treatment for produced water was analyzed based on patent application years, countries, main applicants, and each technologies.

오일 생산 과정에서 발생하는 부산물인 생산수(produced water)는 오일폐수(oily wastewater)의 대부분을 차지하기 때문에 환경적인 측면이나 자원적인 관점에서 볼 때, 생산수에서 오일성분을 추출 및 제거하는 기술은 매우 중요하다. 생산수 처리기술은 크게 물리적 방법과 생물학적 방법 그리고 화학적 방법으로 나눌 수 있다. 본 논문에서는 생산수의 오일제거 기술의 분류, 장단점 분석과 함께 연도별, 국가별, 출원인별, 세부기술별로 기술동향 특허분석을 하였다.
