Lime Kiln Dusting
In this study, the heating rate as main parameter has been investigated with its relation to particle strength and size distribution. Four different lime samples were tested; three ordinary lime muds and one lime sample from the electrostatic precipitator.
Carbon dioxide affected the degree of calcination negatively but had only a small impact on the particle size distribution. It was a tendency that a higher heating rate gave more particles in the smaller size fractions which might increase the severity of lime kiln dusting as heat is transferred further back in the oven with the sensible heat of the dust particles and thereby increase the heating rate.

Tall Oil Solubility in Industrial Liquors 2019-582
Tall oil is one of the most valuable by-products from the kraft pulping of softwood. It has a broad spectrum of applications including chemicals, detergents and fuel to combustion engines, and is partly a renewable alternative to petroleum. Even if it is just a minor part of the wood that is converted to tall oil, the volumes produced are significant due to the massive amounts of kraft pulp that is produced. The value per ton of tall oil is also relatively high. High yield of the tall oil is thus important both for economic and environmental reasons.
