“…Although evaporative cooling tank reactors are currently used in industry, little quantitative structural information is available regarding their dynamic behavior. Some earlier work on evaporatively cooled reactors may be found in refs – . Examples of processes using evaporatively cooled tank reactors include alkylation, oxidation, and polymerization processes.…”

This work characterizes the dynamic behavior of reactors with evaporative cooling. The process under consideration is a continuous stirred tank reactor used to carry out an exothermic irreversible first-order reaction with heat removal through the wall as well as by partial evaporation of the reacting liquid followed by return of the condensate to the reactor. Bifurcation analysis is used to classify the stability character and the types of multiplicity and oscillatory behavior to be expected. A variety of practical situations is examined, including cases of volatile reactant, volatile or nonvolatile product (liquid or solid), and volatile solvent. For a fixed vapor flowrate to the condenser, the dynamic structure of reactors with evaporative cooling is qualitatively similar to the case with wall cooling alone. Other cases show significantly different structures. Cases with five steady states and two regions of three steady states are found with evaporative cooling operation, and for some conditions even seven steady states may be possible. A rich variety of dynamic behavior is predicted.

“…Our simulations indicate that for some sets of parameters either two fill-up states or a fillup, a dry-up, and a steady state may coexist at the same operating conditions. It is worth noting that an experimental observation of fill-up and dry-up states was reported by Hancock and Kenney (1977) for the isothermal reaction between gaseous methanol and HCI in the presence of a concentrated aqueous solution of zinc chloride. While their reaction system and reactor differ from ours, their article underscores the pitfalls that need to be avoided in the start-up of this reactor.…”

“…Huang and Varma (1981b) have determined numerically that oscillatory behavior is possible-but not highly probable-in nonadiabatic reactors in which a fast pseudo-first-order reaction occurs in the liquid. Hancock and Kenney (1977) have reported oscillations in the formation of methyl chloride from hydrochloric acid and methanol in a two-phase reactor in which the reactants enter and the products leave in the gas phase, but reaction occurs in the liquid phase. In this case, the oscillatory behavior resulted mainly from a complex interaction between the product vapor pressure and the reactant partial pressure.…”
