Adsorption systems for cryogenic plants

摘要

This paper studies the possibility of increasing the efficiency of adsorption systems of cryogenic pilot plant for separation of tritium and deuterium. Equipment is composed of an catalyzed isotopic exchange module how the tritium is extracted from tritiated heavy water. An important process in this way is ripping extract moisture from wet hydrogen isotope exchange column. In the present configuration, the cooling is done by passing hydrogen gas through the adsorber where we find within the molecular sieve 13x. Tests were made for both heating phase (adsorption) and for the regeneration (desorption). The conclusions presented in this study show the possibility of using nitrogen cold for the stage of adsorber regeneration. Cold nitrogen derived from liquid nitrogen station, which has a daily rate of loss of cold gas, thus making the recovery of energy dissipated into the environment and an important environmental factor. Monitoring of process parameters was done by two methods, infrared thermography and thermocouple type k with the computer data acquisition system via USB 3.0 interfaces.
