Online $$^{222}$$ 222 Rn removal by cryogenic distillation in the XENON100 experiment

European Physical Journal C: Particles and Fields, 2017
We describe the purification of xenon from traces of the radioactive noble gas radon using a cryogenic distillation column. The distillation column was integrated into the gas purification loop of the XENON100 detector for online radon removal.

The Dependence of the Feasible Separation Region on Feed Quality and Column Equipment

Chemical Engineering Transactions, 2018
For zeotropic mixtures with C- or U-shaped distillation lines, the feasible separation region is bound by two elements: a product composition multitude and a generalized distillation limit. The generalized distillation limit demarcates the sloppy splits (

Reusable surrogate models for distillation columns

Computers & Chemical Engineering
Surrogate modeling is a powerful methodology in chemical process engineering, frequently employed to accelerate optimization tasks where traditional flowsheet simulators are computationally prohibitive. However, the state-of-the-art is dominated by surrogate models trained for a narrow range of fixed chemical systems and operating conditions, limiting ...

Design of a Fully Heat-Integrated Pressure-Swing Distillation for Close-Boiling Separation

Chemical Engineering Transactions, 2018
Enlightened by recent progress in pressure-swing distillation (PSD) and double-effect heat integration, this work combines these two concepts for close-boiling separation, by using two fully heat-integrated columns operating at different pressure plus a ...

Isopropyl alcohol recovery by heteroazeotropic batch distillation [PDF]

, 2010
Solvent recovery is becoming a major issue in the pharmaceutical and specialty chemical industries. Solvent recovery by conventional batch distillation is limited by the frequent presence of azeotropes in the used solvent mixtures.
