“…Bartlit et al (2) ' 3 ' reported that the overall HETP value (-5 em) for Heli-Pak was almost equal to that for Eglin from their experiment using a hydrogen isotope distillation column. But no detailed information concerning the experimental conditions and results obtained was given in their reports.…”

Characteristics of a cryogenic distillation column having a small inner diameter (-2 em) were studied by separating N 2 and Ar for Dixon Ring, Coil Pack, Helix and Heli-Pak. The size of the packings was -1/6 of the inner diameter of the column. The overall HETP value represented no dependence on the vapor flow rate regardless of the packing species used. A tendency common in the four packing species was that the discrepancy between the calculated and experimentally observed Ar concentrations at the middle of the column was enhanced by the decrease in the vapor velocity. This result is ascribed to the phenomenon that the effective vapor/liquid interface area of a portion near the large condenser differs from that near the wire holding the packings. Packings having small void fractions and densely-coiled structure like Coil Pack made this problem more serious. Dixon Ring has an exceptionally large void fraction, nevertheless it presents an adequately large vapor /liquid interface area. In fact, it presented the best set of results of the lower pressure drop, smaller HETP and more readiness in predicting column behavior by the stage model.

“…The secondary function of the ISS is to recover and recycle D 2 to be sent towards storage. The ISS is expected to be based upon one or more of the following technologies: thermal cycling absorption process (TCAP) [6], other chromatographic techniques [7], and/or cryogenic distillation [8]. Although TCAP currently appears as a promising option for LIFE, ongoing work is being devoted to refine the system requirements and identify possible interface issues.…”

Abstract. The Laser Inertial Fusion Energy (LIFE) engine is a laser-driven inertial fusion energy system being developed with the goal to deliver fusion power in the next decade. A pre-conceptual design is being developed for the LIFE fuel cycle, with the purpose of maximizing the potential safety advantages of fusion energy. Some key features of the LIFE fuel cycle include a high tritium fuel burn-up fraction, a relatively high tritium breeding ratio, low tritium permeation from the coolant/breeder, and limited tritium inventories throughout the facility. The present paper offers an overview the pre-conceptual design of the LIFE fuel cycle, including a summary of the development plan for the delivery of the related tritium processing equipment.

A computer code is developed for analysis of dynamic behavior of a single cryogenic distillation column. A dynamic simulation study is performed for the lead column in a typical column cascade which consists of four columns and two catalytic equilibrators.The atom fraction of protium in the bottom product and the reflux ratio are regarded a s the controlled variable and the manipulated variable, respectively. Fluctuation or change of the feed composition is considered a s the disturbance and the PI control scheme is introduced for a constant value control.The criteria are derived, which can be used in setting the choice of the two PI controller parameters. Investigated are the effects of the controller parameters on the response of the controlled variable to a step change in the feed composition, and the validity of the criteria is verified. The parameter setting method proposed in the present study has two advantages : it accounts for the strong nonlinearity of the column and it predicts the unstable region which must be avoided in the actual operation.
