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=− Webthe moles reacted from the moles accumulated in the CSTR. Consequently, we must use concentration rather than conversion as our variable in the balance equation. For liquid-phase (υ = υ 0) reactions with constant overﬂow (V = V 0), using τ = V 0 / υ 0, we can transform Equation (6-8) to (6-9) For a ﬁrst-order reaction (– r A = kC A ...
