Device for continuous annular electrochromatography

Inventor: Hans-Jörg Bart

Pub. No.: WO/2010/105841
PCT Int. Appl. (2010), EP2010/001741

An annular gap apparatus (110) for performing a capillary electrochromatography is disclosed. The annular gap apparatus (110) has at least one separator (112) with at least one fixed annular gap (114), wherein the annular gap (114) is at least partially filled with at least one stationary phase (204) and can be filled with at least one electrolyte (136). The annular gap apparatus (110) has at least one feeding system (138) for feeding a starting substance (140) into the annular gap (114). The annular gap apparatus (110) further has a discharge system (162) for collecting at least one component (168) of the starting substance (140) and/or the electrolyte (136) separated in the separator (112). The feeding system (138) is designed to rotate around an axis (144) of the separator (112). The annular gap apparatus (110) is further designed to impinge the annular gap (114) with an electric field with at least one axial component.

System and Method for Simulating and Modeling the Distribution of Discrete Systems

United States Patent Application Publication

Inventor: Menwer Attarakih

Pub. No.: US 2010/0106467 A1

This invention is accomplished, tested and applied through many summer research stay at the Institute of Prcoess Engineering / TU Kaiserslautern

The invention is related generally to the field of mathematical modelling of population balances as a framework for modelling discrete systems. The invention provides an accurate framework for numerical modelling of such discrete systems, which arise naturally in chemical, physical and biological systems. Particular examples are the two-phase chemical reactors (polymer, two-liquid extraction, crystallization & gas absorption), biological systems and aerosol formation. The invented numerical framework introduces the idea of two types of particles: secondary and primary particles, which can fully describe the moments and the shape of the distribution. The interaction of secondary particles can capture discontinuous jumps in the population states as a result of particle splitting, aggregation and nucleation events. The invention provides a hierarchy and evolution in the numerical modelling of discrete systems, which starts by simple one primary and one secondary particles and evolves to the more complex and rich numerical presentation of the discrete system properties.
