에탄 열분해 공정에서 관형 반응기 내벽 온도 조건이 부산물 생성에 미치는 영향

다국어 초록 (Multilingual Abstract)

It is a essential to minimize production of by-products for economically effective petrochemical process. In order to find key factor to achieve the effective process, 2-dimensional computational fluid dynamics considering a variety of physics such as convective and radiative heat transfer and thermal cracking of ethane are carried out. The reactor is modeled as an isothermal tube, whose length is 1.2 m and radius is 0.01 m, respectively. At first, the axial distribution of representative by-products in ethane thermal cracking are investigated in each inner wall temperature conditions. Then the comparison between concentration of propene (C₃H<SUB>6</SUB><SUB></SUB>) and ethane conversion is discussed with respect to inner wall temperature conditions too. Finally, both reaction rate and turbulent kinetic energy are used to identify the production mechanism of C₃H<SUB>6</SUB> under the intersection point in the plot for C₃H<SUB>6</SUB> molar concentration and ethane conversion.
