Abstract
A process by which heat is removed from a reactant fluid to reach the operating temperature of a known pollutant removal method and said heat is recirculated to raise the temperature of the product fluid. The process can be utilized whenever an intermediate step reaction requires a lower reaction temperature than the prior and next steps. The benefits of a heat-recirculating cooler include the ability to use known pollutant removal methods and increased thermal efficiency of the system.
Claims10
A process for performing an intermediate reaction process on a fluid at a lower temperature than the prior and next steps, the process comprising:
- a) providing a first conduit and a second conduit adjacent to the first conduit, wherein the first conduit and the second conduit are separated by a substrate which is common to both the first conduit and the second conduit and permits the transfer of heat between the first conduit and the second conduit;
- b) passing the fluid through a first conduit and into a reaction chamber, whereby heat is removed from the reactant fluid as the reactant fluid passes through the first conduit and the heat is transferred through the substrate to the second conduit;
- c) lowering the temperature of the reactant fluid;
- d) performing the intermediate reaction with the reactant fluid in the reaction chamber to create a product fluid;
- e) passing the product fluid out of the reaction chamber and through a second conduit in fluid communication with the reaction chamber;
- and
- f) applying heat transferred from the reactant fluid in the first conduit through the substrate to the product fluid as the product fluid passes through the second conduit, wherein the first conduit is positioned adjacent to the second conduit with a substrate intermediate the conduits.
