Definitions

  • the present invention relates to chemical or biological reactors generally, and in particular to an apparatus for controlling the temperature within a chemical reactor.
  • Temperature control of a chemical reaction is often the key to obtaining desired products. Where the temperature is controlled, generally the reaction kinetics are controlled. Where the reaction kinetics are controlled, undesired intermediates and byproducts can be diminished or avoided.
  • Traditional temperature control of industrial reactors is generally attained in one of two ways. One method is to control the temperature of the reactants as they enter the reactor. This method fails to address the heat of reaction, which is often responsible for the majority of heat produced or absorbed in a reaction. The heat of reaction can then alter the temperature of the reactants to produce undesirable products. This is especially true for tank reactors.
  • a second method of temperature control of industrial reactors involves the placement of a jacket around the outside of the reaction vessel. In such a case, a fluid of desired temperature is passed through the jacket, thereby cooling or heating the reaction medium. The effectiveness of the jacket is limited by heat transfer properties which are in turn limited by mechanical design characteristics and geometry, including specifically vessel diameter and length.
  • the temperature of the jacket fluid is calculated based on heat transfer requirements for a given reaction medium and reactor design.
  • the required jacket fluid temperature is often below the freezing point of the reactor medium.
  • the reactor contents can freeze along the inside of the reactor wall.
  • the formation of "ice” results in a thicker wall overall and decreased heat transfer efficiency, as well as potentially inconsistent reactor medium composition, and in some cases, destruction of some reactants or products through freezing.
  • the present invention is an insulated chemical or biological reactor (such as a fermenter) system comprising a reaction vessel, an evacuated insulation shell, a plurality of temperature controlling mixing baffles immersed in the reactor contents and a temperature controlling helical channel coil outside of the reactor but inside the evacuated shell.
  • a device designed to control the separation of phases of the working fluid chosen is required and may be external to the reactor. This device is referred to as the phase separator and has two outlets, one for each phase of the working fluid.
  • the temperature controlling mixing baffles are designed to accept the working fluid in a single phase proceeding from one outlet of the phase separator and to, in turn, cause this fluid to change phase therein without carryover of any of the inlet fluid in the evolved phase.
  • the changing of phase of the working fluid in the temperature controlling mixing baffles takes place at a uniform temperature, the level of which is dictated by the thermodynamic properties of the working fluid selected.
  • the temperature controlling mixing baffles are referred to as isothermal mixing baffles.
  • the channel coil is adapted to accept a circulating fluid, specifically of a single phase evolved by the mixing baffles and the other outlet of the phase separator.
  • the particular working fluid selected depends on the intended temperature control purposes, that is whether heating or cooling is desired and the degree of heating or cooling needed.
  • the channel coil is affixed to the outside wall of the reactor in a helical configuration and adapted to receive the single phase of the working fluid evolved by the mixing baffles and the other outlet of the phase separator which flows spirally upward or downward around the outside of the reactor.
  • the channel coil is shaped to have two straight, parallel sides of the coil in contact with the reactor, normal to the surface of the outside wall of the reactor. This right angle contact between the channel coil and reactor wall increases the section modulus of the vessel wall, and thereby increases the mechanical strength of the reactor wall under external pressure. The wall can thus be made thinner to promote better heat transfer across the wall.
  • the reactor, including the mixing baffles and the affixed coil are together enclosed within an evacuated jacket.
  • the separation of the phases of the working fluid is very important for the optimal and predictable operation of the present invention, particularly when cooling of the reactor contents is anticipated.
  • the isothermal cooling baffles are intended to boil the working fluids which enter as a liquid and evolve only a saturated vapor with no liquid carryover in the form of droplets or mist.
  • the isothermal mixing baffles therefore, operate in the boiling heat transfer regime exchanging the latent energy of vaporization (at constant temperature) with the reactor contents.
  • the vapor evolved from the isothermal mixing baffles, as well as the vapor evolved from the phase separator upstream therefrom is commingled and directed to enter the helical channel coil that serves as the reactor external jacket, wherein it exchanges sensible thermal energy with the reactor contents, gaining temperature to approach that of the reactor contents as it travels further along the inside of the coil.
  • the present invention thus controls heat transfer regimes by assuring that distinct single phases will exist in the isothermal mixing baffles (boiling liquid for cooling mode; condensing vapor for heating mode) and helical channel coil (vapor increasing in temperature for cooling mode; liquid decreasing in temperature for the heating mode).
  • the isothermal mixing baffles are vertically oriented, elongated, generally cylindrical devices with an inlet and an outlet.
  • the isothermal mixing baffles may be used for heating or cooling the contents of the reaction vessel. Where heating is desired, a hot liquid or gas can be introduced into the isothermal mixing baffles through the inlet. The resultant cooler liquid or condensed vapor or liquid can be removed via the outlet. Where cooling is desired, upstream of the isothermal mixing baffles inlet there is provided a phase separator to insure only a liquid stream enters the isothermal mixing baffles.
  • the inlet to the isothermal mixing baffles is typically placed into the top of the reactor and a liquid of desired boiling point is allowed to enter the isothermal mixing baffles while the reactor is in use. Where cooling is desired, the liquid selected would have a boiling point at or below the desired reaction temperature.
  • the heating and boiling of the liquid introduced into the isothermal mixing baffles provides for the removal of heat from the reactor contents.
  • the vapor produced from the boiling of the isothermal mixing baffles contents may be taken from the top of the isothermal mixing baffles, comingled with gas emanating from the phase separator and passed through the channel coil surrounding the outside of the reaction vessel.
  • the isothermal mixing baffles are designed and arranged so that their combined cross- sectional area will be such that the velocity of the vapor evolved from the liquid phase boiling therein will be below a critical value, Uc, above which droplets or slugs of the liquid phase will be entrained in the evolved gas and expelled from the isothermal mixing baffles.
  • Uc a critical value
  • the inlets and outlets of the isothermal mixing baffles will be piped in parallel.

Abstract

L'invention concerne une cuve de réaction contenant des déflecteurs de brassage de régulation de température placés à l'intérieur de la cuve servant à l'ébullition d'un liquide. Cette cuve consiste en un puits thermique isotherme. L'énergie de la vaporisation est fournie par le contenu de la cuve de réaction. La vapeur produite par l'ébullition peut être acheminée vers des serpentins de canalisation entourant l'extérieur de la paroi de ladite cuve. Les serpentins de canalisation entrent en contact, de manière perpendiculaire, avec la paroi extérieure de la cuve. Le support mécanique procuré par les serpentins de canalisation permet, d'une part, de réduire l'épaisseur de la paroi de la cuve de réaction et, d'autre part, d'obtenir un rendement de transfert thermique amélioré entre le contenu des serpentins de canalisation et le contenu de la cuve de réaction. L'ensemble du dispositif décrit dans cette invention est confiné dans une coque sous vide, afin d'obtenir une isolation supplémentaire. Le dispositif comprend un appareil actionné de manière gravitationnelle garantissant l'entrée d'un liquide saturé ou sous-refroidis dans les déflecteurs de brassage isothermes. Ceci permet de garantir le déclenchement du changement de phase isotherme.
