Definitions

  • the objective of the present invention is to provide a compact heat transfer equipment, which allows heat exchange between a liquid with high fouling capacity and a fluid at a pressure (greater than 35kg / cm 2 ) significantly higher than the first liquid, without fouling problems and with heat transfer coefficients (between 1 and 8kW / (m 2 .K)) (kilowatts / (square meter kelvin)) similar on both sides of the exchange surfaces of heat
  • the shape of the heat exchanger widely used in the industry of chemical, petrochemical processes, the production and refining of oil and its derivatives consists of a cylinder with a bundle of parallel tubes inside that pass through the plates that close the ends of the cylinder to obtain a first fluid that passes into the tubes.
  • seawater is highly corrosive and prone to soil heat exchange surfaces with minerals and biological deposits.
  • heat exchangers of materials resistant to corrosion and formation of such deposits are used, such as titanium, which is a very expensive metal.
  • heat exchangers in the form of corrugated plates are used, where high turbulence does not allow the formation of biological deposits.
  • plate heat exchangers have typical pressure limitations of around thirty-five atmospheres. Heat exchangers for higher pressures, for example tubes and shell use much more material, in this case high-cost material.
  • an intermediate fluid circuit such as, for example, water demineralized with glycol for gas cooling services at pressures in excess of thirty-five atmospheres.
  • the gas is cooled with an intermediate fluid in heat exchangers that withstand high gas pressure, but made of relatively cheap materials; in turn, the intermediate fluid at low pressure is cooled in titanium plate type heat exchangers, with seawater.
  • the disadvantages of this way of using seawater as a cooling medium are: the double temperature difference, between seawater and intermediate fluid and between intermediate fluid and gas; and the double weight and volume of heat exchangers. If there is a form of heat exchangers that will allow direct use of seawater to cool gases at high pressure with high heat transfer coefficients; both on the water side and on the gas side, which does not get dirty with mineral and biological deposits.
  • a further object of the invention is to have a device that allows to obtain a better heat transfer coefficient, with the same pressure drop, by combining high heat transfer coefficients of fluidized particle equipment with high coefficients. of heat transfer of screen arrangements that induce helical flow in tube and shell heat exchangers; on the side of the shell, achieving a multiplier effect.

Abstract

L'invention concerne un équipement amélioré échangeur de chaleur entre un liquide et divers fluides en phase liquide ou gazeuse, qui comprend un équipement permettant d'obtenir un transfert de chaleur plus efficace entre un liquide et un autre fluide, le liquide pouvant contenir des matières qui dans d'autres circonstances entraînent des dépôts sur la surface d'échange de chaleur et son arrangement produit une efficacité de transfert de chaleur équilibrée entre les deux fluides et permettent des différences de pression substantielles entre eux. Le liquide circule à travers des tubes sensiblement verticaux avec une masse de particules fluidisables et qui se fluidisent. Le second fluide circule à travers une chambre avec un système d'écrans qui applique un chemin de flux hélicoïdal au second fluide. Le trajet hélicoïdal du second fluide réduit la chute de pression, évite les points de stagnation de flux, évite les remous de flux, réduit l'induction de vibrations des tubes, réduit l'encrassement et augmente le transfert de chaleur. L'équipement entraîne l'utilisation de surfaces augmentées à l'intérieur des tubes, afin d'obtenir des coefficients d'échange de chaleur équilibrés entre l'intérieur et l'extérieur des tubes.
