WebAn ideal CSTR shows optimal mixing and well-defined flow behavior that can be characterized by the residence time, or exit age distribution and comparatively higher conversion. WebThe continuous-stirred tank reactor (CSTR) has an inlet and outlet flow of chemicals. CSTRs are operated at steady state (such that the accumulation term is zero) and are assumed to be perfectly mixed. As such, the mole balance for the CSTR can be written as 𝑖0− 𝑖+𝑟𝑖 =0 Solving for the reaction rate yields 𝑟𝑖=− iphone call waiting option
