Fixation of Oleophilic Colloidal Material in Recycling and Papermaking

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Project to be carried out at YKI, Stockholm, Sweden.

Background
Oleophilic colloidal material in papermaking can emanate from e.g. wood resinous matter or from material that enter the papermaking process together with recycled paper, especially ink particles. The oleophilic material gives process disturbances and several additives are used to combat these substances.

Project
In this thesis work we will investigate several new types of additives that can show a potential to absorb oleophilic colloidal substances. The equipment to be used is e.g. a specially designed flocculation equipment in which the shear field and contact times can be controlled in detail. The thesis work will be carried out in collaboration with paper companies and chemical supplier companies.

Requirements
Program in chemical engineering or related topics.
Start: Spring term 2007 (early). 20 credit points.
