摘要:
Heat exchange devices and methods of using same are provided. In a general embodiment, the present disclosure provides for heat exchange devices that are cooling devices having a double helical coil in a phase-mixing-cooling section, a helical coil in a phase-separation-cooling section, and a back-pressure valve intermediate the two coils. The cooling devices provide maximum extraction of the heat content from a heated food product using a direct-injected liquid cryogen, and complete separation of the gaseous cryogen phase from the cooled product, while avoiding the formation of a stable foam. Hybrid direct-indirect cooling devices are also provided, as well as methods for using same.
摘要:
A process for heating or cooling a liquid (5) by contacting the liquid with an immiscible fluid (1), having different temperature and density, in the presence of a heat transfer enhancing media bed (7) inside a contacting chamber (4). The process including the steps of introducing the liquid into the chamber; contacting the surface film on the media bed with the liquid, whereby the surface film provides for maximum contact and heat exchange between the liquid and fluid; and removing the fluid and the liquid from the chamber.
摘要:
The present application relates to a heat recovery apparatus and a method thereof, according to the heat recovery apparatus and a method thereof according to an embodiment of the present application, steam of 120 °C or more may be generated using only one heat exchanger using waste heat of a low-grade heat source in the state of a sensible heat of 70 °C or more discharged in industrial sites or various chemical processes, for example, such as a manufacturing process of petrochemicals, and the generated steam may also be used in various processes, and thus the use of high temperature steam which is an external heat source to be used in a reactor or a distillation column may be decreased, thereby maximizing energy saving efficiency.
