Projektbereich Z - Zentralprojekte

Der Projektbereich Z hat sich im bisherigen Verlauf des SPP als übergreifende zentrale Aufgabe erwiesen. Hier werden Methoden zur mehrdimensionalen Charakterisierung der Partikelsysteme entwickelt. Denn nur, wenn die mehrdimensional-verteilten Eigenschaften hinreichend genau beschrieben werden können, ist es möglich das Trennergebnis zu quantifizieren. Eine weitere Herausforderung stellen die z.T. breiten Größenskalen dar, in denen die mehrdimensionale Charakterisierung erfolgen muss. Der Z-Bereich des SPP 2045 stellt mit seinen innovativen Methoden einmalige Partikeldatensätze bereit, die auch über das SPP hinaus in der Wissenschaft bspw. für Simulationen genutzt werden.

The central project Z1 will provide methods and estimations for the determination of multidimensional particle properties and acts as service partner for measuring tasks from the SPP-members.

Projektbereich A – Beeinflussung des Trennmerkmals

Dieser Bereich befasst sich mit der Fragestellung, wie ein Trennmerkmal so beeinflusst werden kann, dass eine Trennung nach mehrdimensionalen Spezifikationen möglich wird?

Neue, hochspezifische Klassierverfahren für Feinpartikelsysteme erfordern ausgeprägte Trennmerkmale, eine mehrdimensionale Trennung erfordert mehr als nur ein Trennmerkmal. Wichtige Fragestellungen sind:

  • Verständnis der Mikroprozesse (Strömungskräfte, Wechselwirkungen, Benetzung)
  • Steuerung der Trennmerkmale (Vorbehandlung, induziert im Prozess)
  • Prozessentwicklung ((Semi-)kontinuierlich, Modellierung, skalierbare Verfahren)

This specific subproject deals with the separation of particles through immiscible liquid-liquid interfaces. The entrainment of particles in liquid-liquid interfaces is chiefly controlled by their radius and their wettability.

In the field of pharmaceutical and life science products as well as for optical applications, suspensions with particle sizes in the submicron/nanometer range with the highest quality standards are required. Within the top-down synthesis in stirred media mills, for example, wear (abrasion) of the mill components, primarily the grinding media, is a major challenge.

The separation of particle fractions with highly specific physical properties from suspensions has great importance for process success in a number of process engineering processes. The physical properties of a particle collective are directly related to the particle size, particle shape, surface properties and chemical composition of the individual particles.

The agglomeration in liquids or “spherical agglomeration” is based on a three-phase system consisting of two liquids with a miscibility gap and a heterogeneous suspended solid phase. Essential for this process are the surface energies resulting in wetting properties of the suspended particles.

This project is not included in the second funding period, however will run as an associated project.

Projektbereich B - Verständnis der Mikroprozesse der Trennung

Welche neuen Mikroprozesse der Partikeltechnologie (Konzepte, Quantifizierung, Einflussparameter, Betriebsfenster, Kombination) sind geeignet, eine hochspezifische und mehrdimensionale Trennung zu erreichen?

Hier geht es um das Verständnis der Mikroprozesse der Trennung. Wichtige Fragestellungen dabei sind:

  • Ausprägung des Trennmerkmale = Trennschärfe (Einschritt-Prozess oder Kaskade von Prozessen)
  • Orthogonalität der Trennmerkmale = Mehrdimensionalität (nötig für Entkopplung der Trennprozesse)
  • Querempfindlichkeiten der Mikroprozesse = Robustheit (Übergang vom idealen Laborsystem auf reale Partikelsysteme)

The main objective of this project is the development of a method for the preparative fractionation of semiconducting and metallic SWCNTs using a microfluidic system based on asymmetric field-flow fractionation (FFF) and dielectrophoresis of metallic SWCNTs on taxi particles that can be sedimented in the centrifugal field.

This project will not be included in the second funding period.

Goal of the project is to deepen the understanding of continuous microfluidic separation methods (Multi Orifice Fluid Fractioning (MOFF), Serpentine Channel and Deterministic Lateral Displacement Fractioning (DLDF)) utilized for particle separation based on multiple characteristics (size, density and shape). To enable microfluidic separation methods in an industrial context for elevated throughput operation, both enlarged Reynolds numbers and enlarged particle loadings are studied.

In this subproject, the conventional column flotation will be modified by the use of microbubbles and the coupling of ultrasound, in order to achieve a separation for particles smaller than 10 µm. Since microbubbles possess a low buoyancy and the production of high concentrations is technically complex, a bi-modal bubble system of micro- and macro bubbles will be used.

This project will not be included in the second funding period.

Contacts: TU Bergakademie Freiberg

The introduced project aimes to develop a flotation technique, which is able to realize a separation of particles below the 10 µm mark. The concept relies on the nucleation of nanobubbles during decompression on the surface of the particles themself. Surfactants may be used to stabilize the nanobubbles.

The process commonly referred to as „Magnetic-seeded filtration” aims to separate fine paramagnetic particles by agglomerating them with magnetic particles followed by a HGMS (high gradient magnetic separation) step. The aim of this project is to take a closer look at the hetero-agglomeration of ferro- and paramagnetic particles.

The main aim of this project is to develop a new technology for the efficient multidimensional separation of ultrafine particles via a combination of existing flotation techniques. Based on classic froth flotation, this innovative concept will associate the advantages of a mechanical flotation cell that comes with a high particle-bubble collision rate (thus a high recovery) with those from a flotation column with a fractionating effect due to its deep froth (thus a high grade).

In this project it is intended to shed some light on the grounds for the DPC's potential capability to fractionate particles according to their size, shape and material and in dependence of throughput. This understanding shall pave the way for scaling-up such a separation process and to evaluate its potential as a characterization technology for microparticles.

The project focuses on the multi-dimensional particle fractionation applying surface acoustic waves. In conjunction with the pinched flow method, particles will be fractioned with high selectivity in a cascaded manner, regarding their size, acoustic contrast (mechanical properties) and shape. In addition, a novel optical measurement technique based on deep neural networks is going to be developed, which allows for the measurement of the fluid flow and particle distribution as well as the identification of the particle species by determining the size and shape of the particles at the same time. In this way, design rules for such systems shall be derived, to customizable as to the sort, concentration and throughput of the particle suspensions applied.

Projektbereich C - Apparative und prozesstechnische Konzepte

In diesem Teilbereich geht es darum, neue prozesstechnische oder apparative Konzepte auf ihr Potential bezüglich der mehrdimensionalen Trennung zu untersuchen. Welches Potential liefert bei etablierten Ansätzen die Leistungssteigerung in den Betriebsparametern bzw. eine Optimierung des Prozesses? Sind fundamental neue Apparatekonzepte technisch umsetzbar und leistungsfähig?


Theorie der mehrdimensionalen Trennung:

  • Kann man mehrdimensionale Partikeleigenschaftsverteilungen aufstellen und daraus Trennmerkmale herleiten?
  • Wie können die Daten multidimensionaler Messtechnik ausgewertet werden?
  • Gibt es geeignete Optimierungsmethoden zur Lösung des Gleichfälligkeitsproblems?

Apparative Konzepte:

  • Sind neue Apparatekonzepte technisch umsetzbar und leistungsfähig?
  • Sind extreme Betriebsparameter (z.B. hohe Drehzahl, hohe Reynoldszahl, hoher Durchfluss) möglich und zielführend?
  • Können etablierte Techniken zu einem kleineren Partikelgrößenbereich verschoben werden?
  • Welche Prozessparameter sind relevant für eine spätere großtechnische Hochskalierung?

Prozesstechnische Konzepte:

  • Ist ein kontinuierlicher Betrieb durch innovative Verschaltung möglich?
  • Kann online Mess-/Regelungstechnik für gleichbleibende Trennqualität eingesetzt werden?

In this project, we model a switchable selective filter through a geometrically defined microfluidic channel with an array of insulating posts which is superimposed by an alternating electric field. Perspectively, fibreglass membranes can substitute the function of the insulating posts.

A reduction of the cut size and an improvement of the sharpness of cut are hampered by fluid dynamic phenomena around and inside the classifier wheel. At higher revolution rates, vortices are built up between the blades, which cause a remixing of the already classified material. Due to the geometry of the powder feed, streaks are formed, which cause a pre-classification with a low selectivity. These two phenomena shall be investigated in the proposed project in order to realise a high sharpness of cut in the submicron range.
