Abstract

Sustainability, in general, means the protection of environmental resources and economic prosperity, with the consideration of the social, economic and environmental effect, as well as human health and the enhancement of life. Profound consideration about sustainability has to handle the overall cycle of feedstock, resource extraction, transportation and production in addition to the environmental effect. Sustainable development of the chemical industries should be carried out complementarily by strengthening the chemical process safety of the industries. In this respect, chemical process safety can be called an opportunity to enhance the compatibility internationally. Changing new paradigm in chemical process safety is formed from the overall life cycle considering basic design of existing systems and production processes. To improve the chemical process safety, the integrated smart system is necessary, comprising various chemical safety database and knowledge base and improved methods of quantitative risk analysis, including management system. This paper discussed the necessity of overall life cycle in chemical process safety and proposed new technology to improve the sustainability. To develop the sustainable industries in process systems engineering, three S, which include Safety, Stability and Security, will have to be combined appropriate.

지속가능성이란 사회적, 경제적, 환경적인 영향을 전반적으로 고려하며, 인간의 건강과 생활 증진을 내포하고, 환경자원의 보호와 경제적 번영을 의미한다. 지속가능성에 대한 심도 있는 이해는 이러한 환경적인 영향에 대한 고려뿐만 아니라 원료 및 자원채취, 이송, 생산 협력의 전반적인 순환을 다루어야 한다. 화학산업의 지속가능한 발전은 화학공정안전의 발전을 통한 상호보완적인 강화없이 이루어지기 어렵다. 이러한 관점에서 화학공정안전은 국제시장에서 경쟁력 강화의 기회라고도 할 수 있다. 화학공정안전의 변화하는 새로운 패러다임은 현존하는 시스템과 생산공정의 기본 디자인을 고려한 총체적 순환 전 과정으로부터 나온다. 이렇게 화학공정안전을 향상시키기 위해서는 관리 시스템을 포함한 정량적 위험성 평가 방법과 다양한 공정안전 데이터 및 지식베이스를 포함한 통합 스마트시스템의 개발이 필요하다. 본 논문에서는 화학산업안전의 전 과정 순환의 필요성에 대해 언급하였고, 이를 향상시키기 위한 공정안전 신기술에 대해 논의하였다. 변화하는 공정시스템공학에서 사고 없는 지속 가능한 산업의 발전을 위해서는 3 가지의 S, 즉 안전(Safety), 안정(Stability), 안보(Security)의 조합이 적절히 이루어져야 할 것이다.
