The real reactors are often far from the ideal reactors in the book so the chemical engineers must handle the real chemical reactor with diagnosing problems of operating reactors and predicting effluent conversion. To achieve this goal, three factors are considered to describe the characteristics of the real reactors; the residence time distribution (RTD), the quality of mixing, and the model fo..

Many industrial reactions are limited by the rate of mass transfer of the reactants between the bulk fluid and the catalytic surface. Now we have to consider the diffusion term when writing down the mole balance equation and the energy balance equation. 1. Mole balance equation Let's consider the axial dispersion model. Next, we analytically solve the mole balance equation for specific condition..

For nonisothermal, steady-state reactor design, we need to consider energy balance equation plus design equation. 1. Energy balance equation For a closed system, the energy balance equation is For continuous flow reactors, well-mixed open system, the energy balance euqation is 2. adiabatic system (Q =0) We will now consider open systems operated at steady state. Assume Ws = 0, constant CP , ∆Cp=..

For isothermal reactor design, we need to consider mole balance equation, rate law, and stoichiometry in a collective way. Let’s look at each component in the isothermal reactor design. 1. Mole balance equation We shall perform a mole balance on species j in a system volume, where species j represents the particular chemical species of interest. From this equation, we can develop the design equa..

생명공학 기술이 나날이 발전함에 따라 여러 산업분야에서 그의 중요성이 부각되고 있습니다. 1976년 제넨텍사 재조합 인슐린을 대량합성한 것을 필두로 현재 생명공학은 백신개발, 폐수처리, 바이오디젤 생산 등으로 한계를 넘어 새로운 산업분야를 창조하고 있습니다. 반응공학은 생물제품의 산업화에서 생길 수 있는 여러 문제들을 다루는 과목입니다. 따라서 생명공학 기술을 실제 공정에 접목하기 위해서는 반응공학을 필히 습득해야만 합니다. 예를 들면, 당신은 신약을 개발한 A사의 책임자로서 대량생산에 관여하고 있습니다. 그런데 어느 날 갑자기 수율이 낮아져 단가를 맞출 수 없는 문제가 생겼습니다. 이런 급박한 상황에 엔지니어에게 어떤 지시를 내려야만 할까요? 우선적으로 책임자는 정확한 질문을 하여 문제를 파악할 수 있..
