Abstract

Fouling is caused by sedimentation and corrosion of polymer, heavy paraffine, chemicals, heavy organics, asphaltene, etc. in the entire chemical process of heat exchanger, boiler, desalter, etc. Fouling phenomena remains a serious operating problem which results in increased energy consumption, increased pressure drops, reduction or complete loss of products yield, and increased maintenance costs. In order to calculate the separated amounts of foulants and to control the fouling process, the predictive model is developed which is based on Scott & Magat polymer solution theory, Peng-Robinson EOS, BWR EOS, and continuous and multicomponent thermodynamics.

석유화학공정에서 fouling현상은 열교환기, 보일러, desalter 등 주요 전처리 시설 및 공정에 polymer, heavy paraffine, chemicals, heavy organics, asphaltene, resin, metallics, salts 등 불순물들이 침적 및 부식을 일으켜 각종 조업에 있어서 에너지의 다량소비 및 product yield의 감소 또는 공정의 중단으로 말미암아 생산성의 손실이 대단히 크다고 볼 수 있다. 본 연구에서는 석유화학 공정에서 foulants의 분리되는 양을 계산하고, 제어할 수 있는 model의 개발을 위하여 fouling 현상에 대한 modeling을 연속열역학과 Peng-Robinson 상태 방정식, 고분자 용액 이론, 다성분계 열역학 이론 등을 이용하여 fouling 현상에 대한 메카니즘규명과 모델링을 하였다.
